Nutrient cardboard discs are dry nutrient media presented in Petri dishes for colony count determination by the membrane filtration method. They provide a convenient alternative to conventional agar media and feature a long shelf life of 24 months. Supplied in packs of 100 pieces with a net weight of 1,340 kg, the format supports steady throughput in everyday microbiology work. These discs from manufacturer Sartorius are used when membrane filters are placed onto nutrient media after filtration for colony enumeration. The dry cardboard presentation limits the need for freshly prepared agar plates and helps laboratories maintain ready media stocks for viable count testing. They are suited to quality control, water testing, and related membrane-filtration applications that require reliable colony-forming unit assessment. Standard Petri dish handling remains straightforward, while the extended stability profile simplifies inventory planning versus many poured agar media. Produced in Germany, the discs assist research and industrial laboratories that depend on membrane filtration for routine colony count determination and media logistics.

Questions about m Green NPS & gridded MF, 0.8 m
What is this article?
m Green NPS & gridded MF, 0.8 m 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 Media.
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.
