MBS I
Microbiological filtration system
MBS I is the ideal system for optimal microbiological control using membranes. The overall procedure time is reduced to a minimum. The design of the system that consists of an electrical membrane-dispenser, a funnel dispenser and a vacuum manifold, leads to more reproducible results.
  

 

Microbiological filtration systems

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

Features and Benefits
 

  • Simple to use
  • Safe sealing mechanism
  • Shorter preparation time
  • High reproducibility
  • Less waste and better economy due to 50 autoclave cycles
  • Large funnel capacity for foaming liquids
  • Easier to validate
  • Risk of cross contamination is minimised

 

A unique 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 out of the dispenser, the butler automatically makes a membrane available which it has removed from the sterile pack ready for use.

Find the right funnel

The autoclavable plastic funnel for the MBS I is a true innovation. Unlike tedious flame scarfing of stainless steel filtration equipment for sterilization, the new funnel is simple to use and ensures perfect sterility. The new funnels maintain sterility even 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 funnel are only used once, the system offers another solution: a 100 ml funnel which is pre-sterilised and supplied ready for immediate use. A special closure mechanism at the extraction edge ensures that the funnel closes tightly with the membrane.

MBS I Workflow

 

Microbiological filtration systems

1. When taking a new pre-sterilized funnel, the membrane is dispensed automatically.

2. Membrane is placed onto the filter base and the funnel installed.

3. Liquid is poured into the funnel and vacuum is applied.

4. Easy removal of the membrane after filtration.

MicroPlus membrane filter - the plus for stability

MicroPlus membrane filters from Whatman are the ideal addition to the MBS I for the beverage industry. Wherever viscous or particle loaded solutions are being filtered, MicroPlus filters with their matchless stability and non blocking design are the best choice. Filtration speed due to optimised through-flow, ease of use and high reproducibility contribute to the unmatched quality of MicroPlus.

MBS II
Microbiological filtration system
Membrane filtration is a common method of quantifying microorganisms in liquids. However in other filtration systems, the handling is not always easy. The ready-to-use MBS II from Whatman is easy to use and reduces the risk of cross-contamination.
  

 

Microbiological filtration systems
> MBS II - Filtration unit with sterile vent.

MBS II has been specifically developed for microbiological quality control in the pharmaceutical industry. This means that the filtration system is perfectly suited for bio burden tests on raw materials, preparations and non-sterile end products that are carried out by the membrane filtration method. Drinking water investigations and checks on water for injection purposes are also preferred applications for MBS II.

MBS II saves valuable laboratory time, allowing for increased dedication to more demanding laboratory tasks and to an increase in laboratory productivity. The filtration unit allows for variable vacuum arrangement with high filtration speed and consistent high recovery rates.

Features and Benefits
 

  • Rapidity - ready-to-use filtration unit shortens the preparation time
  • Sterility - minimizes the risk of cross-contamination
  • Reliability - easier handling means more reliable usage
  • Compatibility - used with all agar and Petri dish formats
  • Security - in accordance with EP and USP requirements
  • Safety - sterile venting during filtration

 

MBS II Workflow

 

Microbiological filtration systems

1. Filtration of the sample with the MBS II filtration funnel.
 

 

Microbiological filtration systems

2. Detach the filtration unit.

3. Remove the membrane from the filtration unit.

4. Transfer the membrane onto the appropriate media.

The handling of the system is particularly practical with the filtration funnel and membrane combined to form a sterile filtration unit. When filtration is finished, the membrane is transferred to an agar plate or a Petri dish with a simple double-click, ensuring reproducible results. The MBS II system also offers less danger of cross-contamination in comparison to other filtration methods.
