Beschreibung
Nutrient cardboard discs are sterile dry nutrient media supplied in Petri dishes for colony count determination using the membrane filtration method. As an alternative to traditional agar media they offer extended shelf life of 24 months, simplifying inventory management and reducing the need for frequent media preparation. The discs enable clear colony visualisation and accurate microbial enumeration after filtration, supporting applications in environmental monitoring, food safety and pharmaceutical quality control. Packaged as 100 pieces with a net weight of 1,130 kg and gross weight of 1,400 kg, they integrate easily into established laboratory filtration protocols. The dry format ensures handling convenience and long-term stability compared with poured agar plates. Available from manufacturer Sartorius, these nutrient cardboard discs help laboratories achieve consistent colony-forming unit results while saving preparation time. Their ready-to-use design is particularly valuable for high-throughput testing environments that demand reliable performance and reduced media waste.

Questions about Cetrimide NPS & gridded MF, 0.45m
What is this article?
Cetrimide 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 Mikrobiologie.
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.
