CUSTOMISED TRACK-ETCHED MEMBRANE FILTERS

polycarbonate (PC), polyester (PET) and polyimide (PI)

Based on feasibility test results, and after a potential track etching process optimization, we will supply you with test samples suitable:

  • to check membrane efficiency in your applications;
  • to step-by-step further optimize membrane specifications.

After final validation of your proprietary product specifications, large scale manufacturing will be carried out in our clean rooms to supply high quality controlled products accompanied by a certificate of conformity.

Material

  • polycarbonate (PC)
  • polyester (PET)
  • polyamide (PI)

Pore size range

  • pore size from 0.01 µm to 30 µm for PC and PET membrane filters
  • pore size from 0.01 µm to 12 µm for PI membrane filters

Raw film thickness availability

  •  6, 10, 12, 15, 25 and 50 µm thick raw polycarbonate (PC) films.
  • 6, 12, 23 and 50 µm thick raw polyester (PET) films.
  • 7.6, 12, 25 and 50 µm thick raw polyamide (PI) films.

Surface property

  • PVP treated (hydrophilic)
  • PVP free (hydrophobic)
  • proprietary tissue culture (TC) surface treatment

Color

  • white (translucent)
  • colorless (transparent)
  • black, grey

Options for pore alignment

  • multi-angle pores
  • parallel pores (90°)
  • tilted parallel pores
  • buried pores

Options for high porosity

Although the maximal porosity of a standard track-etched filter is around 25%, track-etching technology can be adapted under specific conditions to the manufacture of membrane filters having a porosity above 40%.

  • good filtration selectivity
  • mechanical resistance adequate for their use in filtration device
  • very high flow rates

Other properties

  • suitability for sterilization (autoclave, EtO and gamma-rays)
  • good chemical resistance (tables), biocompatibility and low protein binding
  • maximum operating temperature: 140°C (284°F) for PC and PET membranes; up to 400 °C (752 °F) for PI membranes
