Sartorius Stedim Biotech has added a range of filters to its Microsart range, which is designed to ensure microbiological quality control in the pharmaceutical and biopharmaceutical industries.
Microsart Avance enables efficient, advanced workflows in quality assurance laboratories and meets high safety standards, according to the company.
As a result, the new product line meets the demanding requirements of the pharmaceutical and biopharmaceutical industries.
The single-use filter units, the Microsart Afilter 100 and 250, have been specifically developed for the detection and enumeration of micro-organisms in pharmaceuticals and cosmetics.
It only requires a few steps to go from sampling to incubation using Microsart Afilter and to obtain reliable analytical results.
The filter units are sterile packaged and ready to connect and can be used right out of the box in quality assurance laboratories.
Thanks to the design of the filter unit, the entire sample is filtered, without any liquid retained on the funnel walls.
This eliminates the need for rinsing after filtration, unless required by specific regulations.
The filter and funnel form an all-in-one sterile unit and thus minimise the risk of secondary contamination.
The cellulose nitrate (cellulose ester) membrane combines the effective retention of micro-organisms with high flow rates and optimal colony growth.
Its printed grid facilitates colony counting, especially in the case of microcolonies and relatively high numbers of colony-forming units.
Microbiological analysis using the Microsart Afilter is straightforward; after samples are taken, the sterile filter unit is removed from the package and attached to a filter station.
The transparent filter units with graduated marks on their funnels enable users to readily check the filling volume and the progress of filtration.
The Click-Fit closure on the filter unit can be easily opened and the funnel quickly removed.
In addition, the membrane can be removed as the filter base has notches for the forceps.
After filtration, the membrane filter is placed on a Petri dish with an agar culture medium that is specifically formulated for the micro-organisms to detect, and the colony-forming units are later counted.
Microsart Afilter products are suitable for sample volumes of up to 100ml and 250ml and their membranes are available in a choice of pore sizes and filter colours.
Packaged in trays with lids for use in clean benches or stacked for secure removal using a Microsart funnel dispenser, they offer the most suitable version for any laboratory situation.
Microsart Afilter can be used in combination with all products of the Microsart and Combisart series, without any additional investment.
