Nylon membrane filters can be wet by water easily because they are naturally hydrophilic, providing an high flow rate. It also provides high strength and broad drug compatibility. Cobetter nylon membrane filters do not contain any wetting agents, detergents or surfactants, so they have low extractables, and low protein binding characteristics, often used for filtering aqueous solutions and most organic solutions, especially alkaline solutions and alcohol solutions. It is recommended for filtering DMSO.
Features
• Naturally strongly hydrophilic
• High mechanical strength.
• Chemical compatibility pH 3-14
• Low extractables
• Low protein binding
Applications
• Filtration of aqueous solutions and most organic solutions, especially alkaline and alcoholic solutions.
• Recommended for DMSO.
How to Use a Nylon 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
