Filters are essential in research laboratories and many other industries for removing particulates and creating environments conducive to a wide array of experiments and procedures. The devices come in different forms including in-line filters, paper discs, small capsules, and large ventilation panels. Filters also purify and concentrate the liquids and gases required for testing. For air, this means removing pollution, moisture, and solid airborne particulates; for liquids, this means removing impurities and small contaminants.

Microbiological filtration system, MBS I, Whatman™
Supplier: Whatman products (Cytiva)
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.
