Ready-to-use, ultra-thin 100 or 250 mL Microfi l® funnels eliminate the need for washing and sterilizing after each test and make equipment handling easy. Packaged in convenient stacks of 25 or 30, the funnels are removed as needed from the custom designed funnel dispenser. Such vertical stacking of the funnels also optimizes lab space.
A range of pre-sterilized 47 mm diameter gridded membranes are available with the Microfi l® funnels. Each membrane is individually sealed in pleated band (EZ-Pak® membranes) or in peel back envelopes (S-Pak® membranes). Polycarbonate membranes are also available.
The push-fi t design of the Microfi l® funnels seals tightly to manifold supports without the need for clamps or O-rings. This ensures leak-free operation and uniform microorganism recoveries.
Unlike with conventional fi lter holders, incomplete sealing at the membrane/funnel interface is eliminated resulting in uniform recovery of organisms. The smooth hydrophobic funnel surface repels sample residues and microorganisms to ensure that any microorganisms in your sample are collected on the membrane and not lost on the funnels walls. Pleating and distortion of the wet membrane due to expansion is avoided by the design of the support. As a result, uniform contact between the membrane and the medium is achieved.
Due to the membrane support, fi ltration rates with the Microfi l® fi ltration system are faster when compared to traditional fi ltration equipment.

The Microfi l® fi ltration system method has been established with reference to International Standards allowing biological analysis to be conducted under optimum conditions and conforms to International Standards for drinking water and mineral water.
