Interesting addition funnel
« on: February 21, 2004, 02:59:00 PM »
Baal was visiting another chemhack, and he was showing off his "chem lair" and some of his improvised handiwork. For those drip additions that many reactions require, he uses these chem-resistant IV bags. They come complete with a drip-rate adjustment valve attached, that is just too cool. 8)

That is interesting, but seems a bit overboard. Wouldn't those be expensive or hard to clean? You can get addition funnels with threaded teflon drip valves and they are a hell of a lot easier to clean. Even regular press. equ. addition funnels have good adjustable rates. Personally I wouldn't like having to reorder equipment for purposes like that. I just see repeated orders of things to be diverted for illegal work as a liability. Even if they are cheap and disposable, it would add to the incriminating trash pile. I would prefer to just rinse a glass funnel out with some solvent and pop it into the ultrasonic cleaner. Bam, evidence gone in five minutes.

Just personal preference. It is cool though, because those things have a killer drip adjustment. If I had the means to acquire them without suspicion or ebing looked upon as a junkie and had an incinerator I'd consider it.

What are those bags made of that you speak of? I just don't see them being able to hold some of the oxidising mixtures, solvents, methylating agents, etc, that one might want to introduce by drip addition.

I guess another great thing is that some IV bags hold several liters of fluid. In that case it makes for a cheap addition funnel compared to buying a 4l funnel and trying to transport/store it, making a great addition to a   porto-lab/disposa-lab.

They were acquired cheaply at an auction of a surplus-goods/second-hand goods wholesaler. There are quite an array of materials that they can be composed of depending on intended application obviously. His sole intention was to eliminate the possiblity of another broken piece of glassware added to the pile.
