    Hydrophobic edge membranes are used mainly for colony count and sterility testing of solutions containing substances with antibiotic characteristics. The hydrophobic edge avoids the penetration of any growth-inhibitory substance into the membrane clamp zone wherefrom it could not be rinsed out and the substance could inhibit microbial growth during incubation.

    • outstanding retention rates for microorganisms
    • 0.45µm are acc. to ISO 7704
    • 0.2µm are validated by BCT
    • certified quality
    • Individually, sterile packaged
    The membranes are available in three different materials:
    • Cellulose nitrate (cellulose ester), a material which assures effective retention with high flow rates and optimum colony growth
    • Cellulose acetate, a material which combines high flow rates and thermal stability with very low adsorption characteristics
    • Regenerated Cellulose, a material which combines excellent chemical and thermal stability with very low adsorption characteristics
