Description
Nutrient cardboard discs are dry nutrient media supplied in Petri dishes for colony count determination using the membrane filtration method. As an alternative to traditional agar media they provide a long shelf life of 24 months at room temperature, simplifying stock management in microbiology laboratories. The ready-to-use dry format reduces preparation time while remaining compatible with standard membrane-filtration workflows for quantitative microbial enumeration. Each unit contains 100 pc(s) and is offered by manufacturer Sartorius for routine laboratory applications. Net and gross weight are both 1,332 kg, supporting straightforward handling and storage. Originating from Germany (Niedersachsen), these discs integrate into established colony-count protocols where stable, long-lasting nutrient media are required. Laboratories benefit from consistent media availability without frequent preparation of agar plates. The cardboard disc design is intended for professional microbiological use in membrane filtration procedures that demand reliable colony enumeration under controlled conditions.
This article belongs on Ready-to-use culture media (plates, tubes, bottles), in Culture media & microbiology.

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