Description
Nutrient cardboard discs are dry culture media for colony count determination using the membrane filtration method. Presented as sterile dry nutrient media in Petri dishes, they provide a practical alternative to traditional agar media for microbiological testing. Their main handling benefit is a long shelf life of 24 months at room temperature, reducing the need for frequent media preparation or cold-chain storage of poured plates. Laboratories apply these discs in membrane-filtration workflows to enumerate colonies and monitor microbial contamination in samples. The unit is supplied as 100 pieces with a net weight of 1,340 kg, suitable for regular quality-control and research use. As microbiology reagents from manufacturer Sartorius, the discs are produced in Germany and support standardized colony-count procedures where dry nutrient cardboard media are preferred. This format simplifies storage and readiness compared with conventional agar while remaining aligned with established membrane-filtration practice.
This article is part of Ready-to-use culture media (plates, tubes, bottles), in Culture media & microbiology.

Questions about Endo NPS & gridded MF, 0.45m High Flow
What is this article?
Endo NPS & gridded MF, 0.45m High Flow 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 Life Science & Microbiology.
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.
