Nupore Edge Hydrophobic Membrane Disc Filter - Type EHCN

 

EHCN Membrane are used for sterility testing of antibiotics & drugs containing bacteriostats .6 mm rim is hydrophobic & rest of the membrane is hydrophilic. The Hydrophobic edge does not allow drug to seep under the rim of the filter holder. This ensures complete removal of the drug during flushing so that growth of any micro-organisms which have been retained on the membrane is not inhibited due to the residual drug, improving the sensitivity and reliability of the test.
