Nutrient Pad Sets
Sartorius Nutrient Pad Sets have been used successfully in the membrane filter method for more than 30 years. Practical and easy to handle, Nutrient Pads reduce labor and simplify many microbiological testing procedures. Microorganisms require the appropriate culture media for optimal growth. Nutrient Pad Sets are sterile, dehydrated culture media. Once they are moistened with 3.0 – 3.5 ml of sterile and demineralized (or pure ) water they are ready-to-use immediately. The level of moisture is optimal when an excess ring of water surrounding the NPS is visible.
The standard NPS box contains 100 sterile Nutrient Pads, each of which is individually inserted in a petri dish and sterilized. Ten each of these petri dishes are sealed in an aluminum bag. This special packaging in bags protects the sensitive formula constituents of the Nutrient Pad during transport and storage from fluctuations in humidity and temperature. As a result, it guarantees the high quality of our NPS throughout their entire shelf life up to 24 months. This makes the Sartorius Nutrient Pads Sets unique: No other ready-to-use culture media around the globe assures such consistently high quality and reproducible results up to 24 months.
Compliance with International Standards: Currently, Sartorius offers more than 30 different Nutrient Pad Set types to meet the diverse requirements of microbiological analysis. Aside from the European drinking water directive, they comply with other international regulations and recommendations: international pharmacopoeias, DIN and ISO standards, the American Standards for Water and Foods, mineral water regulations, brewery guidelines, such as MEBAC or EBC, and recommendations of the food industry, such as LMBG, NCA and ICUMSA, etc.
Includes Membrane Filters: All Nutrient Pad Set types are supplied with the appropriate membrane filters, which are also individually sterile packaged. Nutrient Pad Sets are also available with Microsart® e.motion Membrane Filters which are specially designed for the Microsart® e.motion Dispenser and can be conveniently inserted. The membrane filters are then automatically removed from their sterile package. All membrane filters, tailored to meet the special requirements of microbial detection, are available with 47 or 50 mm diameter.
Biosart® 100 Nutrient Media
Biosart® 100 Monitors have been specifically designed for microbiological testing of pharmaceuticals, food, beverages, water and other liquids. These sterile monitors with an incorporated membrane filter and cellulose pad are ready to use. Biosart® 100 Nutrient Media for wetting the pad are available in individually sterilised, convenient plastic ampoules. Each box of Biosart® 100 Nutrient Media contains 50 ampoules with sterile media, each with 2.5 ml and a lot certificate. If stored under proper conditions ( 4°C), the culture media have a shelf life of 12 months (except for Endo, KF Strep, Lauryl Sulfate and Tergitol which have a 9-month shelf life). Biosart® 100 Nutrient Media comply with international regulations and recommendations: International pharmacopoeias, DIN and ISO standards, the American Standards for Water and Foods, mineral water regulations, guidelines of the food and beverage industries. Within the scope of the quality assurance procedure and stringent quality control standards, every batch has passed Sartorius in-house tests for growth promotion and sterility. Tests also include physical and technical parameters. Biosart® 100 Nutrient Media are convenient to use and eliminate the need to handle glass ampoules.
Microorganisms in liquids are quantified by the membrane filtration method. The advantage of this method is that it allows accurate detection of bacteria, yeasts and molds when low counts in a high sample volume are anticipated. Transferring a membrane filter onto an agar medium is a critical step that can be a source of secondary contamination, especially if tweezers are used. Therefore, it is essential to reduce this risk.
The Microsart® @media product line excels in minimizing the risk of secondary contamination as touch-free membrane transfer rules out membrane manipulation. Moreover, these products accelerate your workflow as just a few work-saving steps are all it takes to use them. Microsart® @media products impressively meet the most stringent quality assurance standards, providing consistently reliable, results and time-saving convenience.
As a result of the combined development , the active lid of @media fits perfectly onto the Microsart® @filter base for an effortless and reliable transfer of a membrane filter onto an agar medium.
In addition, the liftable interior lid provides convenient access to select colonies after incubation for further analysis.
Easy to Use
Fits perfectly onto the Microsart® @filter base, thus permitting easy and reliable transfer of a membrane filter onto an agar medium. No force is needed to snap off the funnel from the base!
Safe and Reliable
Touch-free membrane transfer rules out manipulation, minimizing major sources of secondary contamination. This results in the best growth conditions for reliable results.
Innovative click-fit closure permits fast and easy removal of the funnel after filtration.
Culture Media Bottles and Tubes
The traditional culture media for microorganisms is agar media . The media are available in two formats. Agar media in tubes are for pouring agar plates. The content of one tube is sufficient for two 90 mm or three 60 mm petri dishes. Agar media in bottles are the cost-effective alternative for casting plates.
Colony Counter, battery-operated
Compact, handy battery operated colony counter, is as simple to use as a ball-point pen, and has a 4-digit LCD-display. The counter is supplied with an additional marker refill.
