As far as filtration units there are several different options. Millipore offers complete filtration units under the Stericup name. The Stericup vacuum filtration system combines a Steritop filter unit with a receiver flask for processing and storing amounts from 150 to 1,000ml. These are great when filtering things things that aren't heavy in the solvent department. You can pick up cases of 12 from $100-$215 depending on size.

You will need at least a basic hand held vacuum pump to create the vacuum needed to operate these units which can be found for $35 here.

Im guessing by the questions your asking that PG stands for Propylene Glycol. I dont know of a product called PG80, but theres a product called Polysorbate 80 that you will find being sold at places selling products of the nature your asking about. The difference PEG300/polyethylene glycol 300 and PEG400 I believe (its been a long time since Ive worked with liquid orals) is the molecular weight. With the higher the number following PEG the closer it becomes to a solid. I always used PEG300 when using PEG before deciding to just switch to capsules because I didnt care for the ever clear, or PEG I was using in most.

The half life of Anadrol and Winstrol is about 9 hours. I hope this is helpful.

Wow very helpful, thanks alot.
So why did you switch to capsules?

But I know about the Stericup system, but in the video it looks like he has taped the filter unit with the flask? Do you have to do this?

And (sorry for all the questions..) but can you filter eo solutions with the pvdf filter membrane?
