A wide variety of membranes is available to meet the requirements of different tests. These membranes are directly cast on a transparent polyester backing to improve the handling strength. Standard polyester film is 100 μm thick, although other thickness can be available on order.
- Type CNPF - Lower protein binding
- Type CNPC - Higher protein binding
- Type CNPH-N - Highest protein binding
mdi recommends storage of membrane rolls in original foil packing at 15 °C to 20 °C for longer shelf life. The membrane rolls should be kept away from direct sunlight and heat radiators. The membrane is inflammable when subjected to direct heat.
