Membrane Solutions - high quality bottletop & syringe filters

Membrane Solutions is a premier manufacturer of sterile filtering solutions, including sterile syringe filters and bottletop filters for laboratory use. Filters include:

  • 0.22 um and 0.45 um standard syringe filters
  • Bottletop filters with and without receiver bottle

All filters are CE marked and manufactured in a ISO 9001 certified facility. All filters are sterilized by gamma irradiation and sterile-packaged.

Syringe filters

Sterile syringe filters are made from PES membranes with a polypropylene (PP) housing. PES filters feature high flow rates and low protein adsorption and are compatible with a wide range of applications, including filtration of protein solutions, culture media or additive solutions.

Features

  • Reliable sterile filtration, LRV>7 for Brevundimonas diminuta, ATCC19146 Pyrogen-free
  • Large effective filtration area (EFA) of 4.9 cm2
  • Low protein adsorption, excellent flow rates
  • Hold-up volume of less than 120 μl
  • Individually packaged and sterilized by gamma radiation

Applications

  • Ideal for fast filtration of serum-based tissue culture media, biological fluids, fixation buffers and other “hard to filter” solutions
  • Fast sterilization of buffers, culture media or other solutions (PES 0.22)
  • Clarification and prefiltration of aqueous solutions (PES 0.45)
