Description
Nutrient cardboard discs are dry culture media developed for colony count determination by the membrane filtration method. They consist of sterile dry nutrient media supplied in Petri dishes and serve as a practical alternative to classical agar media in microbiological laboratories. Relative to agar plates, this cardboard disc approach is distinguished by a long shelf life of 24 months, supporting straightforward storage planning and fewer media preparation cycles. In use, membrane filters carrying retained microorganisms are brought into contact with the nutrient medium so that colonies can develop and be counted. The product is supplied as 100 pc(s) per pack for routine quality-control and research applications. These nutrient cardboard discs from manufacturer Sartorius provide dry-medium convenience in a Petri-dish format that fits established membrane-filtration colony count procedures. Net weight is 1,280 kg and gross weight is 1,280 kg for the unit pack. Laboratories seeking stable, ready nutrient media for membrane-filtration enumeration can integrate these discs into standard workflows while maintaining consistent media supply for ongoing microbiological testing programmes.

Questions about Tergitol TTC NPS & gridded MF, 0.45m
What is this article?
Tergitol TTC 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 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.
