  Bottles for Nic
Posted by: P2PLeon - 07-04-2018, 11:46 PM - Forum: E-Juice Making 101 - No Replies

Just wondered if the following https://www.ampulla.co.uk/product.asp?st...Position=1 Would be suitable for Nicotine Storage.

As I have 4 Litres of PG based Nicotine 72mg/ml. They came as 2 lots of 4 bottle of 500ml each.

The reason why I am asking is that I would like to decant 1 bottle so it would be easy to use the Nic as and when I need to.

Just made a small batch up of 10ml of Flavour Arts Just Baccy. Never added any nicotine, but vapes nicely. Just do not know what they put in it but is a nice Vape.

Next time I make it I will add Nicotine and make a bigger batch than this.

You really can't go wrong with this fruity favourite from T-Juice.

Simply a one shot concentrate mix which I'd recommend you mix at 15-20%.

What they say :- The lush taste of red berries and black grape is stampeded by verbose overtones of sweet eucalyptus, aniseed and menthol in a flavour that will stay dancing on your tongue for a long time after you have exhaled.

Only £9.99 for 30ml and if mixed at 15% makes 200ml of juice  [Image: grin.png]

  Nicotine Storage
Posted by: P2PLeon - 29-03-2018, 08:53 PM - Forum: E-Juice Making 101 - No Replies

Piratevape has given a very good guide to storing Nic


With the E.U. TPD regulations just around the corner, one way to minimise their effects on your vaping is to stock up with some 7.2% Nicotine Base so you can continue to make your own e-liquid the way you like it. Piratesvape are specialists in providing Nicotine Base packaged specifically to make storing nicotine a matter of buying it, unpacking it and putting it in the freezer. BUT you say - why freeze it? how do I freeze it? how long will it last? Read on...... 



Nicotine WILL NOT degrade if it is 100% pure and nitrogen sealed in dark glass bottles and kept at a low temperature. That's how professional labs keep it so it’s as close as a fact as you will get when it comes to nicotine storage! Obviously, you aren’t going to be able to achieve all those criteria at home (you won't have 100% pure nicotine being the main one) BUT the majority of us could accomplish two of those important criteria. 





Once you add other chemicals such as PG or VG into the bottle and can't remove all the oxygen then degradation occurs. At what rate and the effect is open to question as no one has actually kept PG or VG nicotine base in a freezer for more than about 5 years so far but it will degrade to some degree even if you do keep it in your freezer. The issue really is with the oxygen either from air trapped in the bottle or through energy put into the chemical system via light (UV) breaking down the dilutant (PG or VG), which unfortunately being organic compounds have oxygen in their make up. It's fine normally because the oxygen in the dilutant is attached to a hydrogen, making a diol (O-H) and will not compete for the nicotine but if you add energy into the system the one single covalent bond between the oxygen and the hydrogen can be broken and you have the issue of the spare oxygen running around causing problems. This is the reason to keep the nic base in amber glass bottles and is the same reason that nicotine is kept nitrogen sealed in labs - so there are no spare oxygen atoms. Keeping the nicotine base at low (freezer) temperatures also slows down the movement of the molecules, which obviously slows down any chemical reactions.





Oxygen is nicotine’s main enemy, it converts it to nicotine oxide in an oxidation reaction and nicotine oxide being a charged molecule has free electrons, this is why the colour change occurs (free electron movement between the atomic energy levels). These free electrons can also target other substances in e-liquid such as flavourings and changes their chemical structure, which coincidentally is the reason why e-liquid has a shelf life.



Storage Basics



Always buy the highest % nicotine base you can buy (currently 7.2% legally in the UK) as the less PG/VG you have in the bottle the better and always buy the best quality, the freshest base you can find to start off with.



What to store it in?



Nicotine base should be stored in dark amber glass bottles to stop UV degradation and potential chemical leaching caused by plastic bottles.



How to store it?



Depending on your usage if you bought 1 litre+ bottles then you should decant it into smaller quantity bottles containing the amount you would probably use in 3 or 4 months so that you aren't exposing the majority of the nicotine base to more oxygen every time you want to use it. Once you open a bottle it’s best to store it in a fridge if possible rather than just a shelf at room temperature and ALWAYS out of sunlight. It is worth noting that PG nicotine base remains fairly free-flowing even straight out of the freezer but VG base turns into a gel and will need several hours at room temperature to be useable.





Where in the freezer to store it?



Purely from a safety point of view, it is best to store it at the bottom of the freezer so that if it does leak it doesn't contaminate anything else in the freezer. I know that some people have a separate freezer for their nicotine base but plenty just stick it in with rest of the families shopping! Make sure that the bottle is clearly labelled, not for you but for the other people using the freezer. If you have young children it would be very wise, if not essential, to buy a small freezer to keep in the garage or similar just for your nicotine stocks.





What's better, PG or VG as the Dilutant?



A personal preference really but with regards to degradation then VG has an extra O-H functional group (3 compared to 2 in PG) so it is possible that if degradation did take place it would be quicker in the VG. However VG has a better shelf life than PG, 2 years compared to 1 year generally AND VG’s viscosity works in its favour for once as the more viscous a liquid the less the molecules move about …… so it’s probably 6 of one half a dozen of the other really as to which is best!  



How long will it last?



It would be expected to possibly see and experience noticeable degradation after 5 -10 years storage either in taste or colour. Strength drop would need chemical analysis once someone has stored it for that long to determine but it is believed by many that it won't be anywhere near half.



What not to do



Leave the bottles alone! The less they are disturbed the better. DO NOT open the bottles if you don't need to and never shake them as this introduces oxygen to more of the nicotine base rather than just the surface.

  VG Properties
Posted by: P2PLeon - 29-03-2018, 08:49 PM - Forum: E-Juice Making 101 - No Replies

Vegetable Glycerin (VG):


VG is a colourless (or VERY light tan-opaque), odourless, very viscous liquid, the other common solvent used in eliquid (along with PG). When stored properly, in a cool (<40C), dry environment, VG will remain free from oxidation or degradation for one year. Most highly regard VG for its smoothness and large vapour production, and it is excellent in these two areas. However, VG lacks the robust flavour solubility that PG possesses, and has a quicker expiration date. 


Vegetable glycerin is made directly from vegetable oil — often coconut or palm oil — by heating it to a high temperature under pressure with water. The glycerin backbone splits off from the fatty acids and is absorbed by the water, from which it is then isolated and distilled to obtain the pure product.



Glycerol forms the “backbone” of many lipids, or oils and fats, and there are various processes that can be used to extract it from these substances. Most glycerin is made as a by-product of the manufacture of soap. In this process, either animal fat or vegetable oil can be used. It is heated with a strong alkali, usually caustic soda (sodium hydroxide), which produces soap and a solution of glycerin in water. This solution is then purified by distillation. So when you are reading negative properties of vaping its half-ass research that finds this process then makes assumptions.



Vegetable Glycerin is widely used in the food industry for two main reasons: it has a sweet taste, but has fewer calories than sugar; and it is hygroscopic, that is, it absorbs moisture from the air. It is therefore used both to sweeten foods and to keep them moist. The compound is metabolized more slowly than sucrose — the type of sugar most commonly found in candy and in processed foods — and therefore does not have such a dramatic effect on blood sugar levels. It also does not contribute to bacterial tooth decay. Foods marketed as being low in carbohydrates are often sweetened with glycerin.



There are also medical uses for vegetable glycerin. It is a common ingredient in cough mixtures, due to its soothing properties. Other applications are as a topical remedy for a number of skin problems, including psoriasis, rashes, burns, bedsores and cuts; as a laxative, in the form of suppositories; and to treat gum disease, as it inactivates the associated bacterial colonies.



Glycerin, also known as glycerol, is an organic compound of carbon, hydrogen and oxygen with the chemical formula C3H8O3. It can be made from animal fat or, in the case of vegetable glycerin, vegetable oil. The source of the raw material does not affect the chemistry of the final product, but, since glycerin is widely used in foods and medications, this distinction is important for vegetarians. It is also used as a sweetener and as an ingredient in a number of cosmetic products.



The compound consists of a chain of three carbon atoms, to which are attached hydrogen atoms on one side and hydroxyl (OH) groups on the other. The three OH groups form hydrogen bonds between molecules, giving the compound a syrup-like viscosity and allowing it to dissolve easily in water. Chemically speaking, glycerin is an alcohol, but for food purposes, it is classed — in the USA — as a carbohydrate by the Federal Food and Drug Administration (FDA), because it provides calories and is not a fat or a protein.

  PG Properties
Posted by: P2PLeon - 29-03-2018, 08:47 PM - Forum: E-Juice Making 101 - No Replies

Propylene Glycol (PG):

Propylene glycol (PG) is a mostly inert organic compound. It is clear, colourless and highly miscible with water. It is used in electronic cigarettes as a carrier base to carry the nicotine and food flavours into vapour form with the application of heat from the atomizer coil. Propylene glycol carries flavour better than vegetable glycerine but produces less vapour.



Propylene glycol is, in effect an alcohol, but not in the sense of “get me tipsy” alcohol. It contains two alcohol groups which enable it to be so water soluble. The molecule contains carbon, hydrogen and oxygen with the chemical formula C3H8O2.



Propylene glycol is both odourless and tasteless and has been approved by the FDA as a solubilizing agent for different types of medications. It is also used in the food, cosmetic, pharmaceutical and chemical industries, and is used to generate theatre fog! Its wide use means much is known about the safety of this material.

  Mixing Guide
Posted by: P2PLeon - 29-03-2018, 08:44 PM - Forum: E-Juice Making 101 - No Replies

Mixing your own e-liquid flavours can be a fun, cost-effective and rewarding experience and isn’t nearly as complicated as you might think. With some unflavored nicotine, your favourite flavours and a few simple tools, you can be on your way to becoming a “mix-master” in no time.



The General Idea



All of the juices that are used in an electronic cigarette consist of at least three main ingredients. Like any recipe, these three ingredients can be adjusted to suit your tastes.



• nicotine

• propylene glycol (PG) and/or vegetable glycerin (VG)

• flavouring



Nicotine is the obvious ingredient, and you will want to make sure you mix your juice to the nicotine level that’s right for you. The level of nicotine is expressed in milligrams per milliliter or mg for short. Most vapers will stick to a level of nicotine somewhere between 3mg and 24mg. Unflavored nicotine for mixing usually comes in a higher strength so that it can be diluted to suit individual tastes. Undiluted nicotine can be extremely poisonous and is absorbed through the skin, so great care should be taken when using it. Wear protective clothing and gloves and obviously keep it out of the reach of children and pets.



Propylene Glycol (PG) or Vegetable Glycerin (VG) are used to dilute the concentrated nicotine liquid to the desired strength. PG makes the vapour and is partly responsible for the cigarette-like “hit” that e-cigarette vapour gives the user. Vegetable Glycerin (VG) is smoother and gives less of a throat hit, but creates more vapour. It is often too thick to be used by itself, however. Many vapers prefer a mix of 80% PG to 20% VG while others prefer a 50/50 mix.Most flavourings are PG based and a high VG liquid can be made without the need to add more PG. It’s all a matter of taste.



Flavouring is where a lot of trial and error comes in. While the other ingredients are mixed to exact measurements, the amount of flavour that a mixture needs varies widely depending on the strength of the flavour, the type of equipment being used and of course, personal taste. In general, starting with about 5% flavour and working your way up is a good idea. Even at 5%, though, some flavours will be overpowering and will be best when mixed with other lighter flavours. Flavourings are added by-the-drop to avoid contaminating measuring equipment. Generally, 20-30 drops are in an ml, However, the use of a measuring device ie a syringe is recommended as different bottles will provide a different sized drop and could lead to inconsistent mix when replicated.


The Ingredients and Tools



There really is very little required to get started in mixing your own juice. Here are the basics that you will need:



Nicotine

Propylene Glycol (PG)

Vegetable Glycerin

Flavouring

Measuring cup or graduated cylinder

Small funnel

Pipette or eye dropper

Empty bottles

Latex gloves

Index cards

An e-liquid calculator


E-Liquid Calculators

Mixing is where things get a little complicated. Combining the right amount of just three or four ingredients doesn’t sound too difficult, but figuring out just how much of the concentrated nicotine will be needed can be a challenge. Luckily, there are a number of great people who have taken the guesswork (not to mention the math!) out of it for us. A simple e-liquid calculator is available online and a more elaborate Excel version can be downloaded.



Before we go any further, here are some examples to try out:



Scubabatdan’s excel e-liquid calculator.


eJuice Me Up – a free downloadable program


E-Liquid Recipe Mixing Calculator – an online calculator with flavouring options and costs


eliquidcalculator.com – an online calculator with a number of options


ejuice – and one for your iPhone


Mixing



The calculators will help you to determine just how much of each ingredient is needed to deliver the expected result at the right nicotine level. Let’s start with an example using unflavored concentrated nicotine in PG at 36mg and have as our goal an 18mg solution with an 80/20 PG/VG mixture and 10% flavour. We’ll make 10ml.



A calculator will show that we need the following amounts of ingredients:



• 5ml 36mg Unflavored nicotine

• 2ml PG

• 2ml VG

• 1ml Flavoring (20-30 drops)



Notice that half of the mixture is 36mg nicotine. That’s because we want to reduce the concentration by half to equal an 18mg strength. We wanted 20% VG in the mixture, so 2ml out of the 10ml will be VG. 1ml of one or more flavours will be added to equal 10% and 2ml of PG will make up the rest of our 10ml.



Now is a great time to write down exactly what you have decided to mix. I like to use numbered index cards for each recipe and label the bottle with the corresponding number. The important thing is to know what is in each bottle so that you can repeat the mix exactly. Nothing is worse than discovering that you really like a flavour made a week ago and having no idea of what you put in it.



Use pipettes, a graduated cylinder or measuring cup to measure out the ingredients as exactly as possible so that your nicotine strength stays consistent. The use of latex gloves is recommended when handling any nicotine solution, especially at higher concentration. Flavourings will often be added by the drop rather than measuring because it takes so little of each flavour.



Now it’s time to vigorously shake the bottle and enjoy vaping your new creation! Some flavours will take a little time to fully mix and develop, so don't toss a flavor right away. Try going back to it after a week or so to see if it is any more enjoyable. This is where that note card becomes especially important!

The Kanger Subtank Mini Build Guide

What you get:


.jpg   SubT 1.jpg (Size: 15.01 KB / Downloads: 19)
.jpg   SubT 2.jpg (Size: 14 KB / Downloads: 20)

Inside the box:

The Tank, this comes with a 0.5 ohm OCC stock coil installed.

   


Underneath are the Accessories consisting of a spare glass tank, a full set of replacement O-rings, Muji cotton wick, a spare spaced 0.5 RBA deck coil, spare terminal screws, a 1.2 ohm OCC stock head, the important wee blue screwdriver and the RBA deck with a 0.5 ohm spaced coil installed.

   

First up building the RBA deck with a 0.5 ohm spaced coil wicked with Muji cotton.

Tools and equipment required:

An ohmmeter or a suitable mod
The blue wee screwdriver
A flat bladed jewellers screwdriver
Muji Cotton Wick
A Phillips screwdriver
Scissors
0.4mm Kanthal A1 wire http://www.cloud9vaping.co.uk/epages/yxv.../DIY-WIRE-
A straightened paper clip

   

Making the coil:

Cut off approximately 4" of 0.4mm Kanthal and wrap around the shaft of the small blue screwdriver, keep the wire taught to the shaft as you wrap and you need 5 wraps spacing each wrap an mm or 2 apart, try and keep the wraps spacing relatively even. Each end of the wire should point in opposite directions.
It should now look something like this :

   

Next up with the coil still on the driver compress the coil against the shoulder of the screwdriver so all the wraps are touching then release, you do this easily with your fingers and may have to repeat once or twice. On release, your looking for all the coils to equally spaced and not touching.

Here's the coil compressed, I'm only using pliers as it's easier to get a clear pic.

   

And after releasing straighten the legs with your fingers.

   

Here's the atty and an RBA section

   

The RBA breaks down into 3 parts, the base, chimney and top cap. The base can be difficult to separate from the chimney, if you find this use the points of the scissors to locate in the juice channels from below and then twist off the chimney, remove the top cap from the chimney.

   

Screw the base of the RBA into the base of the atty securely.

   

And then screw the atty base into an ohm meter for stability.

   

Position the coil over the air hole whilst still on the blue screwdriver & ensuring the coils legs are at the bottom.
With the screws loose position the first leg down the side of the first screw and tighten the screw down then secure the other leg. Once secure you can make minor adjustments to the coil position to ensure its central and directly over the air hole by moving the screwdriver.

   

Wiggle the spare Kanthal legs to ensure a neat break, remove the screwdriver and then check the resistance of your coil, you should get 0.5 ohms. You may wish to fire the coil on a mod at this point to check for hot spots and even heating of the coil.

   

Cut a strip of the Muji cotton about 5mm wide for highish VG juice or 7mm wide if you use high PG juice.

   

Moisten one end of the cotton and screw to a point.

   

Place the pointed tip of the cotton into the coil.

   

Then pull it gently through the coil trying not to distort the coil, you need to be gentle here. If you notice the coils are now touching you can ease then apart again to ensure they are evenly spaced and not touching with a flat bladed jewellers screwdriver.

   

Pull the two tails of the wick up vertically and slide the chimney over the wicks and screw the chimney down firmly.

   

Cut the wicks to length at about 5mm above the top of the chimney.

   

Using the jeweller's screwdriver curve the end of each wick down against the inside wall of the chimney until the end of each wick is down on the RBA deck. Try and keep the wick fluffy and spread it out across the whole width of the deck.

   

Now juice up the wick ensuring you soak the whole of the wick including and especially under the coil.
using the end of a straightened paperclip ease the wick on the deck either side away from the juice channels so you can see the juice channels clearly. This is important.

   

Here you can clearly see the exposed juice channels either side.

   

Screw on the RBA section top cap securely.

   

Juice time, invert the tank and squeeze juice in between the Central air tube and the the glass tank until the juice level is just below the top of the air tube.

       

With the tank still inverted, invert the base complete with the RBA section and after locating the RBA hole on the tank air tube screw the two parts together securely.

   

Full tank, leave it to stand upright for 5 minutes, set the airflow to your preferred position, single hole, dual hole or full bore open and you're ready to go.

Here's a Riptrippers video of the above method.





Don't really see the point in rebuilding the OCC heads given the RBA deck gives a better vape and is less fiddly to coil but for those who wish to here's another video on the OCC head rebuild.
