Vaper stuff nic good? I have an experience bought nic from a random shop, which i end up toss it away bcoz scared to use, it looks yellowish and when i think back, those guys selling are just random guy, how do they do dilution

so after that i kinda be careful when buying nic
I don't think the color of nicotine is too much of a big deal, it turns slightly pale yellowish color or even darker yellowish when oxidized depending on how the supplier, seller, stores them.
Fresh nic should be colorless iinm. If the supplier, seller bought in large volume and then they rebottled it in a smaller volume to be sell here there is high chance the nic had been introduce with oxygen thus change the color a bit unless they have a sophisticated lab equipment to eliminates the oxygen completely when rebottling, which I doubt it.
I'm not sure if there is any seller over here that bought a pure nic (which is expensive) and diluted it themselves in PG/VG mix but I highly doubt it. I think mostly bought 100mg in large volume and just do rebottle.
Link below is not anything scientific, but have read anyway:

Don't get TFA ripe banana. If im not mistaken there's oil substance in it and it will expand your rubbers. Hence spoiling syringes and tank O rings.
Ingredients like Key Lime and Ripe Banana always screw up my equipments
I wanna learn more about extracting flavors also. So far I've tried coffee bean with PG as well. But for fruits, there's a need for dehydration machine

There has been a report that the flavor might crack certain plastics, o-rings I'm not sure. Could be though.

I luv u man. thx for the links.
I plan to get a similar scale like your avatar.

No problem. Find some scale that has 0.01 resolution and has "TARE" function. Make sure it has long cut off time as well so you could take your time while mixing.
If you can afford it buy some high quality like American Weigh scales on Amazon, but it is expensive lol.
Mine is nothing fancy but gets the job done just fine, you can find it on Lelong or Fasttech.

Wait, where did you find TFA Key Lime? I haven't been in the loop much nowadays, my buddy just closed his vape shop so I don't get free toys to test and share with you guys.
Got mine from lelong as well. Just make sure it has a 'Tare' button and long cut-off time.
Apparently sex sells plus, it's Malaysia. *shrugs*
Agreed and I might add a bit, go for 0.01 resolution as well.
I found 2 places for your TFA Key Lime:

Err...I'm pretty sure I used the phrase "failed pisang mas extract". Failed...kaput...hangkang...down the drainhole! It was vapable with very good flavor (better than any of the chemical-tasting and scented flavorings out there), but the coil would clog up superfast with banana-scented carbon. Extracts of coffee, tea, star anise, cengkih all ok, and hella lot cheaper than buying flavorings.
And you're absolutely right. Ripe bananas smell like marker pens, and the common chemical responsible for that is ethylene; that's the gas which is produced by fruits to bring on ripening. The riper it gets, the more ethylene there is wafting around it.
I started extracting banana cos I hated the very artificial chemical taste of banana flavorings. There is a partially good workaround that problem though but I can only pass it to you tomorrow. Today's my last day mixing for a certain organization, but I'm still honor-bound by a gentleman's agreement to keep quiet about certain things till 1st March. Not long to go!

Here is the chemical substances found in TFA Ripe Banana they're using to "mimic" the smell and taste of a ripe bananas. Found it on their site.
NOTE - All concentrated flavors are made from these types of molecules, even "natural" flavors
contain the types of items you will see listed in this section.
For example, natural cinnamon that you bake with contains cinnamic aldehyde.
Natural vanilla extract contains vanillin.
* PRELIMINARY DATA *
We will post new data as it becomes available - these are approximations only and are not definitive.| COMPONENT | Percentage | Description |
| Isoamyl Isovalerate | >= 10% | green, fruity apple |
| Propylene Glycol | >= 10% | no taste |
| Isoamyl acetate | >= 10% | sweet fruity, banana-like with a green ripe nuance |
| Eugenol | >= 1% and < 10% | sweet, warm spicy clove with phenolic and woody nuances |
| Limonene | >= 1% and < 10% | citrus herbal terpene camphor |
| Butanoic acid, 2-methyl-, 3-methylbutyl ester | >= 1% and < 10% | fresh green apple and pear with a waxy skin like nuance |
| Neryl acetate | < 1% | floral, rosy, soapy, fruity, pear and tropical |
| Vanillin | < 1% | vanilla, vanillin, sweet, creamy, spicy, phenolic and milky |
| Pinene <beta-> | < .5% | appears in this flavor as a component of a natural extract - piney,minty with spicy nuance |
| Geranial | < .5% | found in natural plant material |
| 3-Hexen-1-ol, (Z)- | < .5% | fresh, green, raw fruity with a pungent depth |
| Citronellyl acetate | < .5% | floral, waxy, aldehydic, with green fruity nuances. fruity pear and apple like |
| Neral | < .5% | found in natural plant materials |
| Propanoate <isopentyl-> | < .5% | sweet, banana, fruity, tutti frutti, apple, melon, tropical and pineapple-like |
The exact percentage of each substances is the property of TPA, but you get the rough "idea" what they're using to get the flavor profile. Some of the flavors they carry might not have a break down list of components like above (mostly their DX version or newer flavors), perhaps they're not ready to make it public just yet but most of their flavors data are out there on their site.
Anyway,
andyng38 you must have a very sophisticated lab equip. to be able to extract your own banana flavor from a raw banana. I find it too much of a variables at play to get it right, for example like you said the sugar content in the raw bananas itself.
I mean who would've thought, while we were mixing our own liquid, they're mixing their own more advance chemical substances just to nailed certain flavors down. lol

The chemists at these flavorings company is impressive.
