Omicron 160047AXED Cellulose Nitrate Membrane Filters, 0.45 um Gridded w/ 5mm Hydrophobic Edge, Sterile, 47 mm Circle

Omicron Edge Hydrophobic Cellulose Nitrate (AXED) membrane filter features a hydrophilic center area surrounded by a 5mm width of hydrophobic edge which prevents seepage under the rim of the filter holder. In antibiotic and bacteriostatic drug sterility testing by membrane filter method, the 5mm wide non wetting edge prevents drug intrusion under sealing rim. Residue of drug in the Effective filtration area is removed completely by consistent rinsing and micro organisms grow well during incubation. This improves the sensitivity and reliability of the test.

Features:

• 5 mm hydrophobic edge
• Individually, sterile packaged
• High porosity
• Lot to lot consistency
• Low extractables

Applications:

• Microbiological testing of antibiotics
• Sterility testing of bacteriostatic drugs
• Microbial recovery with antibiotic drug samples
• Filling machine operations
• Colony Count
