Sartorius Hydrophobic Edged Nonsterile Cellulose Nitrate and Acetate Membrane Filters
The non-sterile membrane filters are made of cellulose nitrate (cellulose mixed ester), cellulose acetate or regenerated cellulose. They can be used for colony counting, particle testing and microscopy. Choose between gridded or non-gridded, membranes, either with or without hydrophobic edge.
Supplier: Sartorius 1310147N
Description
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.
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
