Cobetter GF Membrane Filters are made of borosilicate fiberglass, suitable for filtration of coarse particles or viscous solutions. They have high compatibility with organic solvents, as well as strong acids and alkalis. Widely used in water pollution monitoring, cell collection and liquid scintillation counting.

Features

• Chemical Compatibility pH 1-14.

• Contains binder, high mechanical strength.

• Fast flow rate, large load capacity, good interception effect

• High dirt holding capacity and high temperature resistance

Applications

• Pre-filtering before final filtering

• Protein, nucleic acid or serum sediment filtration

• Air purification filtration and air pollution detection

How to Use a Glass Fiber 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
