How to Use a PVDF Membrane Filter

1. Take one filter paper (not the blue backing paper) out of the box.

2. Place the membrane filter on the funnel assembly.

3. Adjust the sample container on the proper position.

4. Fix with a locker clip or clamp.

5. Attach the vacuum pump to the filtration set.

6. Pour the sample into the sample container and turn on the vacuum.

How to Choose a Membrane Filter

Medium, buffer filtration -- PES membrane

Low protein adsorption filtration -- PVDF membrane

Solvent mixture -- Nylon or Hydrophilic PTFE membrane

Non-polar (hydrophobic) solution -- Hydrophobic PTFE membrane

Polar (hydrophilic) solution -- Nylon membrane

Corrosive solution -- Hydrophobic PTFE membrane

Gas filtration -- Hydrophobic PTFE memberane
