Choose between Sterile or Non-Sterile, with or without Pad & Individually Wrapped or Roll Microbiology Membranes 

Our Gridded Mixed Cellulose Ester (MCE) membranes are ideal for microbiological techniques, such as E. Coli, that require colony counting after incubation.  These Sterile and Non-Sterile white membranes are 47mm in diameter, have a mean pore size of .22um, .45um, .08um and have clearly defined black grid lines that are nontoxic and free from bacterial growth inhibitors.  Packaged individually sealed, loose or in rolls for use in all standard dispensing systems. 

Individually Packed - Sealed and Sterilized in easy-to-peel plastic envelopes.

Loose Packed - Non-Sterile membranes are stacked loose

Continuous Roll - Sterile sealed without protective paper on top of each filter, in a individual package on a band (roll).  The special pleating of each compartment ensures that the membrane is dispensed perfectly flat.  Advantages include operating convenience, speed and less risk of accidental contamination of membrane.
