Biosart® 250 Funnels
The major area of application for Biosart® 250 Funnels is the microbiological analysis of relatively large sample volumes that have a low number of microbes, with membrane filtration being an essential step. In addition, the Biosart® 250 Funnels are also suitable for testing smaller volumes by placing the sample in a few ml of sterile physiological NaCl solution.
Biosart® 250 Funnels have been specifically designed for microbiological testing of pharmaceuticals, food, beverages, water and other liquids. They are sterile, ready to use 250 ml plastic funnels and are designed to be placed onto the bases of a vacuum manifold. A Sartorius gridded membrane filter is placed on a stainless steel filter support. A Biosart® 250 Funnels is simply mounted and the sample is filtered. The funnel is made of polypropylene and is sufficiently elastic for optimal sealing with a bayonet-type closure. Graduations are marked at 50, 100, 150 and 200 ml for easy measurement of exact sample volumes. The large inner diameter ensures a high flow rate. The conical form allows a thorough rinsing of the system subsequent to filtration. No liquid is retained in the filter funnel. Biosart® 250 Funnels allow quick performance of the filtration steps required in the routine.
Microsart® Funnels are sterile plastic funnels. They allow quick performance of the filtrations required in the routine testing of water, food and beverages, pharmaceutical and cosmetic products. A Sartorius Stedim Biotech gridded membrane is placed on a stainless steel filter support and a Microsart® Funnel is simply and practically fitted on. The sample is filtered. The funnel is made of polypropylene and thus is elastic enough for optimal sealing with a click-fit closure. Graduations are marked for sufficiently exact sample volumes. The large inner diameter ensures a high flow rate. The optimized shape allows a thorough rinsing of the system subsequent to filtration.
Biosart® 100 Monitors
The major area of application for Biosart® 100 Monitors is the microbiological analysis of relatively large sample volumes that have a low number of microbes, with membrane filtration being an essential step. In addition, the Biosart® 100 Monitors are also suitable for testing smaller volumes by placing a sample in a few ml of sterile physiological NaCl solution.
Biosart® 100 Monitors have been specifically designed for microbiological testing of pharmaceuticals, food, beverages, water and other liquids. These sterile disposables with an incorporated membrane filter and cellulose pad are ready to use. After filtration, just remove the 100 ml funnel to convert the Monitor into a petri dish. Culture media for wetting the pad is available in individually sterilized, convenient plastic ampoules.
Biosart® 100 Monitors are ready to use filter units designed to be placed onto the bases of a vacuum manifold. Biosart® 100 Monitors ensures the identification of all colonies. The monitors are available in a variety of different types: Monitors with cellulose nitrate (cellulose ester) membranes, a material which assures effective retention with high flow rates and optimum colony growth. The printed grid lines make the counting easier, especially for higher bacteria counts and for micro-colonies, but do not influence the growth. The three various filter colors, green, white and gray (after wetting black), allow the best contrast to the colonies. Monitors with regenerate cellulose membranes, a material which combines high flow rates with high chemical stability, are ideal for bioburden-testing in the veterinary sector, where a lot of products are based on solvents.
Microsart® @filter 100 and 250 filter units are a sterile and ready-to-use combination of funnel, filter base and gridded membrane in one unit. They have been specifically developed for the detection and enumeration of microorganisms in pharmaceuticals, cosmetics, food, beverages, water and other liquids.
The Microsart® @filter range has been tailored to meet individual needs. There are two volume sizes to choose from, 100 ml and 250 ml, different pore sizes and different filter colors for constrasting backgrounds during evaluation. Marked graduations allow accurate sample volumes.The optimal design permits a thorough rinsing of the system following filtration. No liquid is retained in the filter funnel. Optimal sealing to the Microsart® Base 47 mm is guaranteed by the Click-Fit closure. The filter units are available as tray versions with lids, or are stacked in bags for safe removal using the Microsart® Funnel Dispenser.
Microsart® @vance is an entire product family and stands for innovative products for microbiological analyses based on colony count determination. From taking the sample until incubation in just a few easy steps, whilst at the same time minimizing the risk of secondary contamination.All Microsart® products meet the most stringent quality assurance standards, providing reliable results and offering simple, time-saving handling.
Microsart® @vance is advanced colony counting by Sartorius Microsart® Base and Funnel DispenserMicrosart® Base 47 mm is the perfect addition to existing Combisart® and Microsart® Combi.jet stainless steel manifolds. The Microsart® Funnel Dispenser guarantees secure removal of single, sterile Microsart® @filter units. Even after opening the bag, the remaining funnels are protected from secondary contamination.
The pharmaceutical and biotech industries are driven by the need to optimize their work flows and increase efficiency without compromising their level of safety. Products and raw materials used in the pharmaceutical or biotech industry require control of microbial levels during processing and handling. All components of the filtration system must comply with international guidelines, such as USP, EP or ISO standards.
Reusable Filter Holders
Stainless Steel Filter Holders
Stainless steel holders differ in their funnel capacity (choice of 40 ml, 100 ml or 500 ml) and in their valve type (part numbers ending with CS feature sterile venting). They are specifically designed for applications in which particles or microorganisms need to be retained on the surface of membrane filters. Their stainless steel frit filter support ensures uniform distribution of the retained particles over the entire surface of the membrane filter. Special features facilitate the use of these filter holders during routine testing. Their stainless steel taps are easy to turn on and off, and only one hand is needed to use the unique clamp for secure fastening or convenient removal of the funnel.
Glass Filter Holders
These filter holders are available with a 30 ml funnel (filter dia. 25 mm) for small-volume filtration or with a 250 ml funnel (filter dia. 47|50 mm) for large-volume filtration. They can be sterilized by autoclaving (max. 134°C) or by dry heat (max. 180°C). The glass frit ensures uniform distribution of retained particles.
Polycarbonate Filter Holders
Type 16510 is complete with a receiver flask, and can be used with vacuum or low pressure (0.5 bar|7.3 psi is recommended for maximum throughput). Type 16511 is the same as 16510, but without a receiver flask. It is designed for use on a suction flask or a vacuum manifold (e.g. Combisart® systems). Both types can be sterilized by autoclaving (max. 121°C).
