Sartorius Stedim Biotech, a supplier of products and services for the biopharmaceutical industry, has expanded its range of quality assurance products for laboratory use.
The Microsart Avance line joins the established Microsart portfolio and has been specifically designed for microbiological quality control in the pharmaceutical and biopharmaceutical industries.
Microsart Avance enables efficient, advanced workflows in quality assurance laboratories and meets high safety standards.
The single-use filter units, Microsart Afilter 100 and 250, have been specifically developed for the detection and enumeration of micro-organisms in pharmaceuticals and cosmetics.
Just a few steps are all it takes to go from sampling to incubation using Microsart Afilter and to obtain reliable analytical results, according to the company.
The filter units are sterile packaged, ready to connect and can be used right out of the box in the quality assurance laboratory.
Thanks to the optimised 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 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 in 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 an appropriate version for a variety of laboratory situations.
Microsart Afilter can be used in combination with all products in the Microsart and Combisart series, without any additional investment.
