Description
Nutrient cardboard discs are dry culture media supports for colony count determination by the membrane filtration method. Presented as sterile dry nutrient media in Petri dishes, they offer a convenient alternative to conventional agar plates for microbiological enumeration workflows. A key practical advantage is the long shelf life of 24 months, which simplifies stock management and reduces the need for frequent media preparation in busy laboratories. After appropriate rehydration in standard membrane-filtration practice, the discs support growth and counting of colonies retained on membrane filters. The pack comprises 100 pieces with a net weight of 1,345 kg and comes from manufacturer Sartorius for routine water, beverage and environmental microbiology testing. These nutrient cardboard discs streamline colony enumeration protocols where membrane filtration is already established, helping laboratories keep ready-to-use media on hand. Originating from Germany, they integrate into quality-control and monitoring programmes that depend on reproducible culture conditions for reliable colony counts.
This article is part of Ready-to-use culture media (plates, tubes, bottles), in Culture media & microbiology.

Questions about Azide NPS & gridded MF, 0.45m
What is this article?
Azide 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 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.
