Description
Nutrient cardboard discs are sterile dry culture media supplied in Petri dishes for colony count determination by the membrane filtration method. As an alternative to traditional agar media, they combine ready-to-use convenience with a long shelf life of 24 months at room temperature, reducing the need for frequent media preparation. Each pack contains 100 pc(s) and supports standard membrane filtration workflows in which filtered samples are incubated on nutrient media for colony development and counting. The dry cardboard nutrient format is practical for routine quality-control and monitoring laboratories that require consistent media availability without continuous agar pouring. These nutrient cardboard discs from manufacturer Sartorius are intended for microbiology applications such as water, beverage, and process testing based on membrane filtration colony counts. Net weight is 1,350 kg (gross weight 1,360 kg), with origin in Germany, offering a stable dry-media solution for colony number determination in regulated and research laboratory settings.
This article is part of Ready-to-use culture media (plates, tubes, bottles), in Culture media & microbiology.

Questions about Wort NPS & gridded MF, 0.45m
What is this article?
Wort 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 Microbiology lab supplies.
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.
