Description
Nutrient cardboard discs are specialised dry culture media prepared for colony count determination with the aid of the membrane filtration method. They take the form of sterile dry nutrient media presented in Petri dishes, giving laboratories a practical alternative to traditional agar media for microbiological enumeration. Compared with agar-based approaches, this cardboard disc format is valued for its long shelf life of 24 months, which supports efficient stock holding and reduces the need for frequent media preparation. The discs are used in workflows where microorganisms retained on a membrane filter are cultivated on the nutrient medium for subsequent colony counting. Packaged as 100 pc(s) per unit, the product suits routine quality-control and research applications in microbiology. These nutrient cardboard discs from manufacturer Sartorius combine the handling convenience of a dry medium with a Petri-dish presentation familiar to laboratory staff. Net weight is 1,130 kg and gross weight is 1,280 kg for the pack. By using stable dry nutrient discs instead of freshly poured agar plates, laboratories can streamline membrane-filtration colony count procedures while keeping consistent media available for ongoing testing programmes.

Questions about Standard TTC NPS & gridded MF, 0.45m
What is this article?
Standard TTC NPS & gridded MF, 0.45m is the article on this page. Luminix Health distributes Sartorius for laboratory use. It sits in Ready-to-use culture media (plates, tubes, bottles), inside Culture media & microbiology, in Microbiologie.
A ready-to-use plate, tube or bottle is the medium already prepared and sterile. It saves the autoclave and it expires. The fill volume, the supplements and the storage temperature are the specification. A plate that has dried out or grown a colony of its own is finished.
A culture medium is the food and the solid or liquid home of a microorganism. Dehydrated media are powders the laboratory dissolves and sterilises. Ready-to-use plates and tubes are already that. A Petri dish is the plate. Selective media let one kind of organism grow and hold another back. The formulation and the supplements, not the colour of the agar, are the specification. Reference strains are at ATCC. Methods are on PubMed. Biosafety practice is the WHO laboratory biosafety topic.
