Description
Nutrient cardboard discs are sterile dry culture media supplied in Petri dishes for colony count determination using the membrane filtration method. They offer laboratories a practical alternative to conventional agar media, with the clear advantage of a long shelf life of 24 months. This dry-medium format supports routine microbiological workflows in which liquid samples are filtered and colonies are enumerated on nutrient media. Each pack contains 100 pieces, giving a convenient unit size for quality-control, water, beverage and environmental testing laboratories that rely on membrane filtration. Handling is simplified compared with pouring and managing fresh agar plates, while the discs remain dedicated to colony-number determination after filtration. Nutrient cardboard discs from manufacturer Sartorius fit standard membrane-filtration colony-count procedures where stable dry media and straightforward pack logistics are required. The pack has a net weight of 1,340 kg and a gross weight of 1,348 kg, reflecting the complete set of discs in Petri dishes ready for laboratory use in microbiology reagent applications.
This article is part of Ready-to-use culture media (plates, tubes, bottles), in Culture media & microbiology.

Questions about m Green NPS & gridded MF, 0.65m, 100pk
What is this article?
m Green NPS & gridded MF, 0.65m, 100pk 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 Milieux microbiologiques.
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.
