PTFE Filter

The company is a highly reliable Manufacturer & Supplier of PTFE Filter. The PTFE Filter is a new device with high purity and strong chemical resistance. The thin PTFE membrane (Microsep) in a sequentially numbered poly propylene support rings is ideal for PM 2.5 ambient air monitoring and sampling in aggressive environment. The company offers the best PTFE Filter at the best prices to the clients.

Key Features

  • Convenient : Each filter is individually numbered for easy sample tracking. Each box of 50 filters is sequentially leveled for easy control
  • Precise : Low tare mass provide for accurate gravimetric determination. The unique thermally stable design eliminates curling, keeps the membrane flat, and makes the filter robot friendly.
  • Clean : Manufacture under clean room conditions, these chemically resistant, low chemical background filters permit sensitive interference free determinations.


Applications

  • For air monitoring and sampling in aggressive environment
  • Supported membrane offer increased durability for hostile testing environment or acid aerosol monitoring


Ordering Information
