where to get PG

[kingofswords]

anyone know where to get (cheap) PG ? guess i need pharma grade....around 200mls.

Lloyds chemist do it but you need a prescription which seems a little odd..although it is only 1p.

whats difference between pharma and di-propyl stuff?

[tommk3cab]

The ''di-propyl'' stuff you mention (I assume you mean propane-1,2-diol or monopropylene glycol) is just the chemical name for it, the ''grade'' has nothing to do with this. EDIT: or you could mean Dipropylene glycol which is a different chemical all together (in fact a mixture of chemicals) which is AFAIK no use in vaping (but can be a byproduct in PG production).

The mistral stuff from ebay is apparently all good, www.ebay.co.uk/itm/500ml-PG-MPG-Propylene-Glycol-USP-EP-FCC-grade-99-9-/330373494079?pt=UK_Carfts_Candle_SoapMaking_EH&hash=item4cebcb753f
or this www.ebay.co.uk/itm/500ml-MPG-Propylene-glycol-USP-EP-99-Pharma-grade-better-then-food-grade-/140608454423?pt=UK_BOI_Medical_Lab_Equipment_Lab_Supplies_ET&hash=item20bceabf17

EDIT:The price for the mistral stuff is way out, I think a mistake may have been made, I don't have time ATM to look into it.

RE:EDIT: yeah, if you look here... the prices of the mistal stuff is inconstant to say the least... stores.ebay.co.uk/Mistral-Cleaning-Products/_i.html?_nkw=Propylene+Glycol&submit=Search&LH_TitleDesc=1&_sid=220321476

I've bought my PG from Mistral King . . . there was a time when it was cheaper on Ebay, than on their own website . . . whether that's still true I don't know as I've not bought any for a while.

Cige also does PG.

is the mistral stuff good? can it make a difference which brand or where you get it from?
also can the same be said about nic base?

[tommk3cab]

as long as it is BP grade it should all be near as damn it the same stuff... in theory all PG should be the same stuff no matter what grade it is... Unfortunately some contains impurities... this may or may not make much difference.

The mistral stuff should be ok (but the other link is considerably cheaper for the quantity you want and would/should be equally as good)

Some nic bases can be a bit dodgy and smell funny or be a bit orange/yellow... I have had some which is pretty stinky and yellow but it vaped fine @18mg.

i thought bp just meant boot pharmacist.....as in the vg they sell

does pharma grade mean its been mixed and transported in containers that wont react badly to it and its basicly sterilised or clean?

It means it has gone through further purification processes which then allow it to be used as a pharmaceutical product, food grade being the next step down on the ladder followed by industry grade.

Personally in the case of PG (and any other chemical/compound) I find the grading system abhorrent. PG is a noun not an adjective, if it was called ''vaping fluid'' then it could contain all manner of things but PG shouldn't be anything else other than PG, what I mean is, BP grade (or pure)should be the only one which exists, IMO of course. I studied chemistry for a while, this is the only reason why this bothers me I think.

British Pharmacopoeia (BP),
Is the official British reference work setting forth standards of strength and purity of medications and containing directions for their preparation to ensure that the same prescription written by different doctors and filled by different pharmacists will contain exactly the same ingredients in the same proportions. The first British Pharmacopoeia was published in 1864 by the General Medical Council; it superseded the London Pharmacopoeia, which had been published since 1618.

I was going to suggest cige myself but beaten to it , I've had some quality PG and VG from him at what I would consider a fair price

[farzooks]

The same grading system applies to many other chemical reagents, as I came across when I was making biodiesel (I'd known this from years ago, and forgotten it).
During the testing phase I had need of some indicator chemicals, so hied off to a lab stockist and was stunned at the cost of lab-grade reagents. It turned out the need for dead - on accuracy wasn't really required, so I was able to buy less highly-graded chems for considerably less money. The actual processing chemicals involved in the making of biodiesel, sodium hydroxide and methanol, were available in bulk and were cheap industrial grades.

In the case of PG, food grade would be more than adequate and I suspect the ebay listing showing £18 for 0.5L is for lab or BP grade.

Some one found a great deal a few weeks ago for BP grade PG. I am sure it was Johanino:

That's the one Macca and I was so uncertain about it I blagged myself a bottle free

Worth getting at that price ...prompt delivery in secure packaging.
