Description
Nutrient cardboard discs are sterile dry culture media in Petri dishes designed for colony count determination by the membrane filtration method. They provide a durable alternative to agar media, distinguished by a long shelf life of 24 months that eases laboratory storage and planning. In use, the discs support microbiological colony enumeration following membrane filtration of samples, helping laboratories maintain consistent colony-count workflows. Each unit comprises 100 pieces, offering a practical pack size for regular testing in quality control, process monitoring and related microbiology applications. The dry nutrient cardboard presentation reduces reliance on freshly prepared agar while staying focused on membrane-filtration colony-number determination. Nutrient cardboard discs from manufacturer Sartorius address routine needs for stable dry culture media in Petri-dish format within membrane-filtration protocols. With a net weight of 1,340 kg and a matching gross weight of 1,340 kg, the pack delivers a complete set of discs for microbiology reagent use in colony count determination.

Questions about Malt Extract NPS & gridded MF, 0.8 m
What is this article?
Malt Extract NPS & gridded MF, 0.8 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 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.
