Description
Nutrient cardboard discs are intended for colony count determination using the membrane filtration method. They are dry culture media presented in Petri dishes and provide an alternative to conventional agar media. The principal advantage of this format is a long shelf life of 24 months, supporting stable laboratory media stocks without frequent replacement. Each unit comprises 100 pc(s) of nutrient cardboard discs for microbiological colony enumeration workflows based on membrane filtration of liquid samples. These discs from manufacturer Sartorius are dry nutrient media that reduce reliance on freshly prepared agar plates for routine colony counting. With a net weight of 1,345 kg and a gross weight of 1,360 kg per pack, they are supplied ready for professional laboratory use. Produced in Germany in the Lower Saxony region, the product aligns with standard membrane-filtration colony count procedures. As microbiology reagents, nutrient cardboard discs offer a practical dry-medium option whenever extended media availability and straightforward Petri-dish presentation are required for colony counting after filtration.
