Good Day all, I am new to this place but I am not new to some people, Some may know me form E&W or xinventions or some other board, But wile reading and surfing this palce for months now I knew it was time to join, There are some seriously smart people in here with some great ideas, One of them would be madog hehe, Any who I wanted to throw this topic out to you guys, I seen it referred to a few times in an aspirator thread not long ago, Any ideas thoughts inputs any thing at all would help me out a lot, I am not made of gold and a good vacuume is close to golds price LOL. Sorry If i reposted a thread thats here before But I searched and found nothing!

Thanx ;)

sorry, maybe I am just drunk :D but what exactly is your question?????

VooDooMan - 27-11-2003 at 20:52

Humm, I need ideas on how to turn a fridge pump/compressor into a vacuum for my glassware setup, Maybe I was drunk when I wrote that thread?

thanx

I once ripped the compressor out of an old dehumidifier for use as a vacuum pump. It pulled about 50mm Hg.

Fridge compressors work (I am told)

no

fridge compressors only work for an amplified fluxcompressor to exaggerate the hermitic closed garage-streamings in a twarped vortex setup.

Never use the search function of this board - it is poisoned and delivers your soul directly to hell - your body goes to belgium for vultures experiments.


but except this:
welcome.


hint:
"how to turn a fridge pump/compressor into a vacuum for my glassware setup"
1. put compressor into glassware
2. make compressor vanish by magic spell
3. where was compressor now is vacuum
(if the wrong spell was used there maybe a frog or a princess or some gems instead of the vacuum - try again)

I am given to understand that 2 in tandem produce a very good vacuum but they arnt designed for continuus use and get attacked by fumes so they dont last long. Assuming that is a solvent doesnt get dissolved into the pump oil and kill the vacuum first like with most mechanical pumps without traps.

Is an aspirator with or without seperate water pump not an option? The fact you dont need a cold trap is a big help itself provided you dont mind a little water vapour.

you have to blow a fan at them against overheating and change oil from time to time. (mineral oil is fine, just fill in at the sucking side - old oil is spewn out at the blowing side).

High quality fridges provide high quality compressors, the older the better they are (in times of no energysaving oversized compressors were usual).
I love ELECTROLUX.
For european experimentors probably the first choice in householdware.
