Title: Easy vacuum filtration without apparatus
Post by: claude on September 12, 2004, 02:29:00 AM

An easy way to do a vacuum filtration without the right apparatus is to use a bottle, on wich you place as usual your funnel and your filter. You must make a hole in the top of the bottle, and you use a simple cleaner aspirator placed on this hole to make the vacuum. Beware, the liquid must drip really down the hole if you don't want to see it enter in the aspirator. You can prolung the end of the funnel with a pipe to avoid that. Tests must be done with each home-made apparatus. I have tested it and it works.

Title: if whatever your filtering has any inclination

if whatever your filtering has any inclination at all to "clog" the filter then a vacuum cleaner will definitly not be sufficient.
refrigeration/air conditioning service pumps are cheap and have a low vacuum. (e.g. $US 250 for this

)

if this is too expensive there are pneumatic venturi vacuum pumps, for instance this for $US 14

i believe they are saying it pulls 28.3inHg below atmospheric, or about 1.6 inHg.
there is also the hand operated mityvac for about $30, but i can't find how much vacuum it is capable of pulling

(Vitus_Verdegast: "UTFSE", Chemicals & Equipment)

Vacuum cleaner motors tend to get too hot if not allowed pull air as fast as normal thoughput allows. This often leads to the motor overheating and irrepairably burning out.

Instead of vacuum, you can also use positive pressure from a foot pump or the like.  An easy alternative for some filtration procedures.
