HDPE plastic container question for STB tek MHRB 2nd time

[dimyself]

I apologize for the newb question but I've searched and dont see exactly what I/m looking for. I've only extracted 1 time before using STB 100g MHRB powder and I think it was Noman's tek I followed?

THe biggest problem I had was it was extremely hard to extract the naptha pulls from a 1 gallon jub due to the wideness. I kept pulling the other layers along with the naptha. I was using a SS turkey baster, which also is definitely NOT ideal. Any other ideas for what to use to suck the naptha up that work better than a SS turkey baster?

I know the teks mention using glass, but my reading at the time seemed to suggest that glass is more fragile or doesnt work as well as plastic? Does anyone know a better HDPE plastic container that will support at least 100g MHRB pulls and is TALLER/THINNER than traditional milk jugs?

Will a 1/2 gallon jug be enough to hold all the stuff for 100g extractions? I don't think so, I seem to remember the 1gallon jugs being more than 1/2 full with everything in there?

I liked the plasic, but need something taller/thinner so I can pull more naptha without the brown layer coming with it...Also would like to use something other than the turkey baster, that also didnt work great.

Again I'm sorry but I've searched and all i seem to find is people using mason jars, 1 gallon jugs with turkey basters

thanks everyone! I eagerly wait replies so I can begin preparing ....and I've got a GVG/torch on the way, can't wait!!

Use pipettes - takes a bit more time but it is worth it. I use 4 litre HDPE milk jugs as you can usually get the naptha in the thin handle part to suck it up easily with the plastic pipette. I normally use 2 pipettes, one for the sucking of clean naptha and the other for sucking up a mix of naptha and mimosa/NAOH and squirting it down the handle.

Hope this helps

hdpe bottles are ideal. I use 100gm in a 2 liter bottle. The bottles are good because you can squeeze the solvent up near the lid and it is alot easier to grab your pulls. I have heard of people doing 500gm extractions in a 4 liter bottle wow hey. I don't trust glass because it can become fragile.

You can also pour your solvent off into something easier for your turkey blaster to grab, like a beaker or a jar that isn't so wide. If your extremely carefull you can pour off most of the solvent without getting any base, not so easy in something Thats wide tho.

I use an awesome little hdpe squirty sucky bottle thats used for fuleing up remote control petrol cars.

Good luck

sweet!! thats exactly what I was looking for, just wanted to make sure 2ltr was big enough for the 100g + mixture...it sounds like it will work alot better than 1gallon big jugs thats for sure

Haha and thats funny you mention squirty sucky bottle... I think I may have one of those from rc gas days lol

Wow, that pic looks good, I think it's the oil on the last few extractions?

When I did my extraction, i got a thick gold yellow oil about a pyrex bottom full. But I couldnt figure out what to do with it haha

Hey thanks for you guys for your help! I like the idea of 2 liter, or maybe even a 3 litre? Have you tried a 3 litre ever I wonder if it would work well... So, those 2 litre coke bottles I'll check there hdpe compatibility

 

[dimyself]

Can you clarify which 2 liter bottles you're talking about? I'm reading about them, and it seems they are a different material than hdpe, they will not leach plastic or toxins? Which number should I be looking for on the bottom?

or maybe I should get a 1/2 gallon milk jug?? that would be hdpe

Phillips lists two major classes of chemicals that are not compatible with HDPE: aromatic hydrocarbons, and halogenated hydrocarbons. The basic aromatic hydrocarbon is benzene (a major component of gasoline); others are toluene (also called methylbenzene), and the three xylenes (o-, m-and p-xylene). Others include naphthalene (moth balls), and pdichlorobenzene (also moth balls). These aromatic hydrocarbons "permeate excessively and cause package deformation," says Phillips.

Wellm, I know hdpe is safe thats what i used last time and thats what alot of people here recommend. What I don't know is what material is 2 liter coke bottles I don't think they're hdpe are they safe to use??

Or should I use 1/2 gallon milk hdpe jug? Will that be enough to hold all material??

WHat I might do is just use the 1 gallon jug since its big enough for all the mixture, then transfer naptha each time to a tall/thin container of some sort

Wellm, I know hdpe is safe thats what i used last time

So...your evidence that it's safe is that you used it last time? On what grounds do you know it's safe (and why would you think that you know better than the company that makes the plastic you're referring to)? Did you have your product tested for plasticizing agents? This seems like an argument for something that you'd like to be true, rather than something that is true.

I've seen naphtha and xylene eat through HDPE plastic. I've seen HDPE containers significantly degrade over time when exposed to these solvents. Just because it doesn't immediately dissolve does not mean you do not wind up with plasticizers in your product.

Also, if you know you've used HDPE in the past, how do you not know what containers are HDPE?

Do they not have glass where you live?...something about a plastic milk jug and caustic chemicals makes me cringe. I had plastic pipettes once till they melted now I use glass ones. but to each his own.

You seem intent on arguing or like you're irritated that I didnt say what you want to hear

Alot people on here use hdpe plastic (uisually jugs). I never read how hdpe would leak/be unsafe to use for extractions?? So, are you right that hdpe jugs are unsafe or are the others in this thread who stated they use hdpe jugs/bottles right??

As it was mentioned that glass can be/become fragile to use for this? So how do you KNOW the glass will hold up and what kind of glass to use to ensure it doesn't crack/break?? I don't mind using glass if hdpe truly is toxic, but I don't quite understand the line of when its fragile and when it's ok to use glass... There seems to be some misinformation about this.

Is hdpe toxic immediately upon extraction or if you leave material in there for awhile?

And you say how do I not know what hdpe is again, it seems like you're a little bitter or trying to start something here? I know, (through the search function I might add) AGAIN as already stated numerous people use plastic water/milk jugs and it is common knowledge that they're hdpe. That doesn't mean I'm some kind of genie to be able to determine by looking at another plastic if it's hdpe or not lol

*EDIT I should point out honestly, the answer to your quesion is i don't know that hdpe is safe, I ASSUMED it was safe because I see so many people recommending it and never see people say it's unsafe. SO thats what I used last time. One thing for certain is my spice last time came out white/beige/yellow and smelled like plastic. I've gone through most of it, and I haven't noticed any health problems, although I don't do it all the time either

My comments were made in the spirit of harm reduction...namely reducing the risk you are putting yourself in. I'm not bitter...although I do find it tedious to repeatedly chime in on these threads only to be told that HDPE is perfectly safe, when the manufacturer says it isn't. Glass will not leach into your product, end of story. There are numerous posts around here that document the degradation of HDPE in the presence of non-polar solvents. There's no need for there to be an argument over this; it's your body, do what you will.

Glass IS chemical resistant. Sure some types of glass can be more or less durable than others same as some types of plastic, but that's mostly looking at it in an "impact resistant" way. Most people use plastic milk jugs because it's what they have laying around the house, and don't feel like going out and buying a jar. it is entirely possible that plasticizers from the plastic will leach into your final product. I would personally have an issue with that and would be thinking about it as I smoked.
Besides Naptha is a Hydrocarbon and Hydrocarons over time break down HPDE plastic.

** I got a couple PM's asking me to include the legend for the chart, but I can't seem to link it so I'll type it out below...

E: 30 Days of constant exposure causes no damage. Plastic may tolerate for years.

G: Little or no damage after 30 days of constant exposure to the reagent.

F: Some effect after 7 days of constant exposure to the reagent. The effect may be crazing, cracking, loss of strength or discoloration.

N: Not recommended for continuous use. Immediate damage may occur. Depending on the plastic, the effect may be severe crazing, cracking, loss of strength, discoloration deformation, dissolution or permeation loss.
...Hope it helps**

I'd say get some glass, better to be safe than sorry if you can get a Borosilicate glass container it's about the best inexpensive glass you could find.

You seem a bit hostile yourself and almost intent on using plastic, we're only looking out for your safety.

i've got a 1000 ml flat-bottomed Pyrex measuring cup i mix lye & water & rootbark in... for pulls i transfer it to a mason jar... the cup cost 8 bucks... the mason jars are a dozen for 15 bucks or so... & since i started mixing the lye in the pyrex, the only glass that's broken has broken because i dropped it on the floor... go glass mang, it's safer & damn sexy looking sitting on a counter...

if HDPE is unsafe what do you use as a stopper?
