Description
CN membrane filters, white | black, sterile, 3 µm are Microsart® e.motion membrane filters intended for colony counting, particle analysis and microscopy. The 3 µm pore size and white-on-black colour scheme support clear colony visualisation and routine microbiological evaluation. These membranes are designed for use in the Microsart® e.motion filter dispenser and are supplied in a specially developed individual sterile pack without interlayer paper, sealed to keep each disc ready for use. Special folding of the single packs helps keep the membrane correctly positioned during handling and application. The filters can also be used together with nutrient pad sets from manufacturer Sartorius for culture-based workflows. Delivered as a pack of 300 pieces with a net weight of 0,388 kg, they suit laboratories that need consistent, dispenser-ready membrane filters for particle and microbial assessment.
This article is part of Microbial identification, hygiene monitoring & rapid tests, in Culture media & microbiology.

Questions about CN; white - black; sterile; 3 m
What is this article?
CN; white - black; sterile; 3 m is the article on this page. Luminix Health distributes Sartorius for laboratory use. It sits in Microbial identification, hygiene monitoring & rapid tests, inside Culture media & microbiology, in Life Science & Microbiology.
These kits name an organism or detect a residue on a surface faster than a full culture. A swab, a lateral-flow strip or a chromogenic reaction are the forms. The organisms or the residues the kit claims, and the ones it misses, are in the pack insert. A negative is only as good as that list.
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.
