Nutrient cardboard discs are sterile dry nutrient media presented in Petri dishes for colony count determination by the membrane filtration method. This convenient format provides a practical alternative to conventional agar media while supporting reliable microbial enumeration in routine laboratory workflows. The dry nutrient base is rehydrated during use and enables clear colony development after filtration of liquid samples. A key benefit is the extended shelf life of 24 months at room temperature, which simplifies inventory management and reduces preparation time compared with freshly poured plates. Supplied in packs of 100 pieces with a net weight of 1,333 kg, the discs are ready for immediate integration into standard membrane filtration protocols. Manufactured by Sartorius, these nutrient cardboard discs originate from Germany and are intended for microbiology laboratories performing quantitative colony counts on water, beverages, pharmaceuticals or environmental samples. Their stable dry form minimises waste and storage constraints while maintaining consistent performance across multiple test series. The product supports efficient quality-control and research applications that require reproducible results without on-site media preparation.

Questions about Yeast Extract NPS & gridded MF, 0.45m
What is this article?
Yeast Extract 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 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.
