While searching for a new HDPE extraction vessel, I came across this spray pump made entirely of HDPE. The design would be an interesting way to siphon the NPS layer off the base and into a sep funnel. Using a small amount of pressure, one could seemingly regulate the transfer stopping when any base is being picked up. Just an idea. I'd appreciate any thoughts or feedback.

i thought hdpe2 was suggested for nps like xylene

Warning to those using plastic containers/instruments in extractions

Use glass, not plastic -- even HDPE.

Remember this is going into your body. It is a good idea to take every safety precaution possible.

Regarding safety, I've had a thick glass carboy break during extraction, (from lye etching) This is scary and dangerous.



Xlylene/Tolulene is the NPS I'm referring to.

No, your next best bet is to get glass that won't become brittle from the lye -- preferably lab-grade glass.

Thanks for all the info. So pyrex won't etch and break like a glass beer carboy?

One more question, could stainless steel be used for an extraction?

Are you positive it was lye etching and not thermal shock that caused your glassware to break?

I am not aware of any problems with stainless steel, but I've done zero research on using it for extractions.

I'm not entirely sure. It was only the second time I used it for extraction. (lye slowly added to water) I can't really afford a 2 gallon pyrex vessel, so I'm exploring other options. A friend was telling me about a product called Better Bottle.

In a nutshell –BetterBottle PET carboys are BPA-free, DEHP-free, plasticizer-free, light weight, and safe .

BetterBottle carboys are made from a special, scientifically tested, polyethylene terephthalate copolymer (PET), which does not have the disadvantages of other plastics.

BetterBottle carboys are: are: 1) Designed to be strong, scuff resistant, easy to handle, and essentially unbreakable, 2) Pure – Taste- and odor-free, BPA-free, DEHP-free, and plasticizer-free, 3) Virtually impermeable to oxygen, 4) Clear and colorless, and 5) Incredibly light weight. BetterBottle carboys are not at all like other plastic carboys. The special PET, used to make BetterBottle carboys, is non-absorbing, non-porous, and non-wetting (hydrophobic), so it will not carry over flavors from one batch of wine or beer to the next and it is easier to clean and sanitize than glass or other plastics.

If you need something inexpensive yet strong/thick glass look for Carlo Rossi wine at your local store. Not as good as lab glass, but it will get the job done w/o the fear of easily breaking or plastic contaminates.

^top of the line wine
lol
edit: a rossi bottle wouldn't be my choice for extraction vessel

lol - I wasn't recommending the wine.

Have any other suggestions or just naysaying?

That's why I boil it down to a sticky resin and consume it in capsules.

i used this with a good degree of success..

Found a good solution. 5000 ml Erlenmeyer Flask

This will be perfect for 500 gram extractions.

That's more like it! Borosilicate ftw.

the quickest and easiest way i have found to siphon of the nps is simply a small glass cup and a pair of gloves, press it into the top until it breaks the surface tension of the nps and it fills up, im sloppy the first time not worrying about picking up the cactus aswell as it goes into the first 1 litre pyrex jug, then i let it settle for 5 minute before i pour it through a cotton filter into the salting container. i use about 300ml size cup so takes me no time to get out a litre. i used to use a turkey baster (for my mhrb xtractions) but cup is a lot quicker. would be hard with one of those carboys though as the top is too small.....

i had another glass mason jar crack on me recently, so i used a hdpe bucket for mixing and a hdpe container that my xylene was shipped in for titrations.

if its being recrystallized i cant see a problem with plastic contamination.
I can however with spilling everything everywhere.

yup i'm just naysaying cheap glass used as extraction vessel- seen too much broken cheap glass

i use hdpe plastic- and dont personally see any evidence of it degrading. and dont understand peoples fear of hdpe plastic(lacking evidence of toxicity from the trace amounts you might possibly consume.) if people are so concerned why would they be using NPS in the first place?

dg, thank you for your feedback about HDPE.

Do you have any thoughts about this pump? Do you think it could work well to remove Xylene from the base?

i'm open to hearing arguments against hdpe. beyond irrational "plastic is bad mmkayy"
like scientific evidence that trace hdpe exposure is harmful to your health etc

I'm guessing you missed this post from Snozzleberry... unless you think he (and the manufacturer of HDPE) are full of BS. It's a little stronger than "plastic is bad mmkayy". I'm open to hearing arguments that plastic is safe, btw, other than "plastic is safe, mmkayy".
