General description

The bi-directionally supported Millex-GP50 filter is a sterilizing filter for aqueous solutions. It removes microorganisms, particles, precipitates, and undissolved powders larger than 0.22 micron (μm). The sterile Millex-GP50 filter is non-pyrogenic and non-toxic. This single-use product consists of a 0.22 μm membrane filter sealed in an acrylic housing.

Application

Sterile filtration of tissue culture media, additives,buffers, and water.

Preparation Note

  • For use with peristaltic pump, a pump drive and pump head that delivers a constant speed of 60 revolutions per minute (rpm) is recommended. This generates an average flow rate of 100 mL/min.
  • Recommended tubing: 4-9.5 mm I.D. silicone rubber or latex tubing
