Membrane filter units are versatile tools used to test samples for microbial contamination. Many units are disposable, eliminating the cleaning and sterilization required with reusable funnels. The membrane filtration units can be installed in relatively small facilities that blend into the surrounding area and can be fully automated to significantly reduce the required amount of operator attention. Sterile units are ideal for microbiological testing of water quality, food, raw material, sterility, and product quality.

Microbiological filtration system, MBS I, Whatman™
Supplier: CYTIVA WHATMAN
MBS I is an excellent system for optimal microbiological control using membranes. The overall procedure time is reduced to a minimum. The design of the system, which consists of an electrical membrane dispenser, a funnel dispenser, and a vacuum manifold, leads to more reproducible results. All components are sold separately. The modular system provides flexibility to select the hardware and accessories that best suit the unique and varied workflows of the user.
The special sealing technique ensures easy handling and high integrity of the funnel and membrane during filtration. This keeps any cross-contamination to a minimum.
