Codice prodotto. 11740626

Descrizione

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
