Filtration
HINT !
more Hints more Filtration Hints

  • Single Stage Pump Only required/needed !
    Duel stage Only relevant for large container faster pump down
  • DON’T USE a Rotary Vane pump ( normally oil lubricated ! XXX)
    too high a vacuum ( typical <10mmHg ) can fracture the membrane open the pores
    Humid air can rust-up/sieze the pump . . . eventually
  • DANGER Glass Bottles can break AND Plastic Bottle filters can collapse particularly with “oil” filtration (it softens THE plastic) & “ALL . . . use Common Sense !”

TOO
Slow ?


use YOUR
common sense

Check for leaks
use THAT Vacuum Gauge
that;s what
 it’s for !

It’s a viscosity problem !
warm the mix ! ( but 50C max!)

Sterilisatio n ?
0.2um is a must !
otherwise
4x 0.45 faster

dirty (unseen) media may clog the filter
don’t use
el cheapo “crap” media

use a Large Membrane Diameter eg
 90:47:25mm (SF)
x 12:3.5:1 Speed
 

use a more compatibe membrane material
New PES
for water and most mid- polarity “oils” vs PVDF ???

Use a
Syringe Pump
(35psi max)
 or maybe a Peristalic pump (5-7psi max ???)

Use Due Diligence

OUR DISCLAIMER Appllies !

NO returns accepted . . . for stupidity !
