is there a product commonly available that contains pure DCM? SWIM doesnt like the idea of ordering pure DCM off the internet, plus it seems a little pricey 8.69 USD per half pint. What do some of you use for your DCM solvent?

What do you use for DCM?

pure DCM would be called DCM. Its >99% pure dichloromethane if its good quality.

I think what you really should be asking is, what is the best product to distill DCM from?

i need a good distilling tek. I dont have much lab equipment and I'm wondering if it would be better to just buy the pure DCM. I found an empty bottle of it in the chem lab at school but i have no idea where a full bottle would be. Is there a way to distill it without fancy lab equipment. Any help or push in the right direction will be appreciated.
just get it pure
there's no way of safely distilling this stuff without an all-glass setup, as it will chew through most plastics.

Yeah, I agree with benzyme there. You need a professional still setup that's all glass or all metal.
If using glass, it needs to be put together with good sealing joints using PTFE joint sleeves or PTFE pipe tape. You should not use joint grease because it’s soluble in DCM. Many things are soluble in DCM, that’s why it’s such a great solvent for extracting pretty much every plant on earth.
If you use metal, it needs to be very well put together so that there are no leaks. All joints should be sealed with PTFE pip tape or welded together. A good plumper should be able to put one together. Actually this is much better than using glass in terms of safety. You can make a huge one out of steel and not worry about it ever cracking. Most large scale stills are all metal. The problem with metal is that you can’t see your solvent, so you can’t tell if the metal boiling flask is empty or not.
If you make a homemade still and it leaks, your whole room will get DCM vapor all over it. I would never enter a room with DCM vapor in it without lots of protection (goggles, gas mask, suit, etc.).
DCM is not flammable so in that way it’s one of the safer solvents to distill.

Back in swims 'hive' days, he used to cook naked.... next to a shower, after having some stuff explode and stick to his clothes etc.... Not reccomended.
But he definatly noticed a minty, tingling sensation in his balls when heating DCM as well as methanol in his nutsack.... LOL those vapors can definatly pass through thin membranes/skin. Absolutely.
He laughs now, and most certainly has a diff attitude towards his own health and safety these days.
haha

agreed with what you said earlier; dcm is a fairly commonplace chem with relatively low saftey rating (2), that most small chem supply stores would sell it without any questions.

probably the same as in the US.
not a particularly watched chem, chloroform might be. though you could probably get a liter of either from a small chem supply house (they typically deal with big distributors) without any problem.
I'll walk in and ask for it like I'm buying a Dr. Pepper. It's when you act paranoid that they may think you're using it for something illegal. the worst they can do is deny you the sale.
