Cobetter MCE membrane is composed of cellulose acetate and nitrocellulose, and the surface is smoother and more uniform. MCE membrane is widely used for biological and environmental monitoring applications. MCE membrane is suitable for filtration of water-based solvents, not resistant to strong acid, strong alkali solutions, and most organic solvents.

How to Use a MCE 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 membrane
