Description / BorsoTEF

BorsoTef is a range of superior pleated PTFE membrane filters with PFA supports. These cartridge filters are suitable for use within a number of microelectronics, process and chemical applications. This chemically inert filter range offers the removal of fine particulate from 0.05-10 micron in challenging operating conditions.

Features and Benefits:

  • Excellent flow characteristics
    Optimised up to 95% porosity, uniform pore size distribution and filtration area with low pressure drop, high flow rate and long service life.
  • Full traceability
    All BorsoTef cartridges are identified with a batch serial number and supplied with a Certificate of Quality.
  • Controlled manufacturing environment
    BorsoTef cartridges are manufactured in an ISO cleanroom environment by fully gowned staff, minimising the risk of contamination.
  • Fast rinse up time
    All filters have been flushed with ultrapure DI water (18.2 Megaohm-cm, TOC less than 10ppb).
  • Low binding and fouling
    BorsoTef filters are manufactured using surface modification agents to ensure minimal extractables and ensure purity performance is not compromised.
