Nutrient cardboard discs are sterile dry culture media supplied in Petri dishes for colony count determination using the membrane filtration method. They provide a convenient alternative to conventional agar media, with the key advantage of a long shelf life of 24 months. This dry nutrient format supports microbiological colony enumeration while reducing the need for frequent media preparation associated with traditional agar. Each unit is offered as a pack of 100 pieces, with a net weight of 1,329 kg and a gross weight of 1,340 kg. The discs from manufacturer Sartorius are produced for laboratory use in membrane-filtration-based colony count workflows. Originating from Germany, they are classified among microbiology reagents and are intended for use as ready dry nutrient media in Petri dishes. Their cardboard disc design is tailored to the membrane filtration method, enabling straightforward colony number determination after filtration. With a documented shelf life of 730 days, these nutrient cardboard discs help laboratories maintain stable stocks of culture media for routine microbiological testing.

Questions about Chromocult®* NPS & gridded MF, 0.45 m
What is this article?
Chromocult®* NPS & gridded MF, 0.45 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.
