Description
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.
