Microbial Enumeration | Bioburden Testing
Effortless Membrane Transfer with Microsart®@filter and Microsart®@media
Safeguard patient safety and manufacturing process performance and count the number of microbes in your sample using touch-free membrane transfer to agar.
Assurance that pharmaceutical products are free of microbiological contaminants is a key quality control (QC) requirement for patient safety. Membrane filtration is the regulatory-preferred method for microbial enumeration/bioburden testing (USP <61>, <62> and <1231>, Ph.Eur. 2.6.12, JP 4.05), which quantifies colony-forming units (CFUs) of aerobic mesophilic bacteria and fungi on the agar plate medium. However, transferring the membrane filter to the microbiological medium is one of the most common sources of contamination and false-positive results.
Microsart® filters are ready-to-use sterile filter units that combine a funnel, filter base and gridded membrane filter into a single unit. Microsart® @media dishes are pre-filled with different types of agar medium and sterile packaged. Together, they enable a touch-free membrane transfer that reduces the risk of secondary contamination.
Microsart® @media’s patented adhesive lid transfers the filter and positions it precisely onto the agar plate to allow touch-free transfer of the membrane.
The integrated venting function of the new Microsart® Manifold minimizes the risk of cross-contamination during filtration.
Microsart® @media’s convenient, liftable interior lid provides easy access to colonies after incubation.
Media comes sterile packaged, ready-to-use, and pre-filled, according to USP (<61>) and EP (2.6.12).
Filter base and gridded membrane comes combined with ready-to-use 100 mL or 250 mL funnel.
The bayonet closure allows easy adjustments onto - and removal from - the stainless-steel manifold.
Use Microsart® @media and @filter with the Microsart® e.jet transfer pump and Microsart® manifold.
The fully autoclavable, Microsart® Manifold is made of high-grade stainless steel.
Product Highlights
Microsart e.motion Membrane Filters & & Microsart e.motion Filter Dispenser
Make Membranes Move
Sartorius membrane filters feature the widest selection, three filter colors, two diameters and a variety of pore sizes. The various filter colors and distinctly visible gridlines provide the best contrast with colonies for easy and reliable quantification and identification. The membrane filter band specially designed for the Microsart® e.motion dispenser can be conveniently inserted and easily changed as needed.
- Membrane filters for colony counting, particle testing and microscopy
- Outstanding recovery rates for microorganisms
- Individually sterile-sealed filters are packed on a special pleated band
- Convenient dispenser enables automatic, touch-free membrane filter dispensing
Microsart® Manifolds
Choose between different sizes of manifolds, from single to multi-branch. The manifold sizes are connectable with each other by quick connection for easy adaptation to daily workload. Depending on the application and criticality of product to be tested, users can choose different funnel and filtration units, from reusable to single sterile solutions.
Convenience
Tool-free assembly/disassembly facilitates handling, cleaning and sterilization of the manifolds.
Quick connectors on both sides of the manifolds improve usability and allow pump positioning on the left or right side.
Silicone feet prevent the manifold from sliding on the work bench and facilitate overall handling.
Performance
The Manifold is made of 100% stainless steel. The high quality of the material (Stainless Steel 316L - 1.4404) and the use of one material type ensures long work life of the manifolds.
Ergonomics
Low height ensures efficient and ergonomic operation under the laminar flow, especially when heavy bottles must be repeatedly lifted over the funnel.
Easy to operate valves minimize the risk of strain injuries when numerous samples must be analyzed in a short period of time.
Adaptability
Depending on the number of daily tests, users can choose between one, two, three or six-branch manifolds.
The number of filtration positions can be extended easily using the quick connectors. This facilitates adaptation of the installation to the workload.
Do you need to test samples containing aggressive chemicals and adsorptive biological substances like antibiotics for microbial limit testing?
- We have the answer for quantitative detection of microorganisms in aggressive or difficult-to-filter solutions.
