MityVac

MITYVac

Hand Operated Pump
Vacuum Piston Chamber 30cc -x 15 “pumps to evauate 500cc “sealed” Solvent Bottle
> Slow; so obviously not for
fast filtration or large bottles/chambers

Note : a Hand Pump
can “potentially” get down
to > ~ 100mm HG

 BUT ONLY use at Max Vac
of 250mm Otherwise risk “implosion” of GL45 Bottles
( Safety-coated version(s) are now available )

Use a Diaphragm Vacuum Pump for faster uninterrupted use
 (~200-300mm vacuum) ( higher vacuum may fracture polymeric membranes ) Order these separately !
PES is a more modern “Universal” type polymer for
faster filtration; mid-polarity to hydrophyllic matrixes
