Description
Nutrient cardboard discs are intended for colony count determination using the membrane filtration method. They are dry culture media presented in Petri dishes and provide an alternative to conventional agar media. The principal advantage of this format is a long shelf life of 24 months, supporting stable laboratory media stocks without frequent replacement. Each unit comprises 100 pc(s) of nutrient cardboard discs for microbiological colony enumeration workflows based on membrane filtration of liquid samples. These discs from manufacturer Sartorius are dry nutrient media that reduce reliance on freshly prepared agar plates for routine colony counting. With a net weight of 1,350 kg and a gross weight of 1,350 kg per pack, they are supplied ready for professional laboratory use. Produced in Germany in the Lower Saxony region, the product aligns with standard membrane-filtration colony count procedures. As microbiology reagents, nutrient cardboard discs offer a practical dry-medium option whenever extended media availability and straightforward Petri-dish presentation are required for colony counting after filtration.
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.
