General description

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.
The special sealing technique ensures easy handling and a good integrity of the funnel and membrane during filtration. This reduces any cross contamination to a minimum.

Features and Benefits
• Simple to use
• Safe sealing mechanism
• Shorter preparation time
• High reproducibility
• Funnels can be autoclaved up to 50 times
• Large funnel capacity for foaming liquids
• Easier to validate
• Risk of cross contamination is minimized
• A combination of comfort and progress

The combination of the funnel dispenser and the Membrane-Butler E in the MBS I system is unique. When a funnel is taken from the dispenser, the butler automatically dispenses a membrane from the sterile pack ready to use.

Find the right funnel
The autoclavable plastic funnel for the MBS I is a true innovation. Unlike tedious flaming of stainless steel filtration equipment for sterilization, the new funnel is simple to use and ensures sterility. The new funnels are provided sterile in a magazine and save time especially when a large number of samples need to be processed by one apparatus.
The funnels (350 mL) are of high grade polypropylene and can be autoclaved up to 50 times. For applications in which funnels are only used once, the system offers another solution: a 100 mL funnel which is presterilized and supplied ready for immediate use. A special closure mechanism at the extraction edge ensures that the funnel seals tightly with the membrane.
