Membranes for Microbiology – Introduction

• Made from Mixed Cellulose Esters (MCE) or Cellulose Acetate: MCE is a mixture of nitrocellulose and other cellulose esters.

• Available with grid lines: Contrasting grid lines facilitate counting colonies on the filter surface and are tested to assure freedom from grid line 3.1 mm squares represent 1/100 of the filtration area of a 47 mm diameter filter (9.6 cm2)
• Convenient packaging: Membranes are available individually wrapped for optimum sterility and also in 10-packs
• Specially tested for microbiology: All 0.45 μm white gridded membranes are tested for Coliform, Fecal Streptococci and Serratia marcescens. All 65 μm white gridded membranes are tested for complete retention and optimal recovery of Fecal Coliform and Saccharomyces cerevisiae. Black and Green membranes are tested for optimal recovery of yeast and total bacteria. All membranes are also tested for uniform wetting, freedom from grid line inhibition and optimal color reactions on appropriate test media
• Membrane certification for individual lot numbers is available on request
