Description
Nutrient cardboard discs are dry nutrient media presented in Petri dishes for colony count determination by the membrane filtration method. They serve as a practical alternative to conventional agar media and offer a long shelf life of 24 months. Each pack contains 100 pieces with a net weight of 1,353 kg, supporting efficient handling in routine microbiological testing. These discs from manufacturer Sartorius are intended for workflows in which membrane filters are transferred onto nutrient media after sample filtration. The dry cardboard format reduces on-site agar preparation and helps laboratories keep media available for colony enumeration without frequent fresh pouring. Suitable for quality control, water analysis, and other membrane-filtration-based viable count procedures, they fit standard Petri dish handling practices. Extended stability compared with many poured agar plates simplifies stock planning in busy microbiology environments while remaining focused on clear colony-forming unit assessment after filtration. Originating from Germany, the product supports consistent media logistics for research and industrial laboratory settings that rely on membrane filtration colony counts.

Questions about Jus de Tomate NPS & gridded MF, 0.45m
What is this article?
Jus de Tomate 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.
