Description
Cellulose nitrate membrane filter 0,45 µm is a sterile round filter with a diameter of 50 mm, finished in black with a printed grid to support visual assessment after filtration. Manufactured from cellulose nitrate and cellulose mixed ester (CN, MCE), the membrane provides a defined pore size of 0,45 µm for controlled particle retention in laboratory sample handling. Sterile presentation allows direct use where a ready-to-apply disc is preferred. The black gridded surface improves contrast for colony counting and documentation of retained material on aqueous filtrates. Supplied in packs of 100 pc(s), the filters suit ongoing laboratory demand with compatible 50 mm holders and funnels. These membranes from manufacturer Hahnemühle pair familiar CN/MCE handling characteristics with a practical grid layout for microbiological and quality-control filtration. The 50 mm round format offers a slightly larger working area than smaller discs while remaining easy to position and remove. Explicit pore-size and diameter specifications help users match the sterile membrane to established protocols and filtration hardware.

Questions about Membrane filter Cellulose nitrate ,0.45 µm, sterile, black, grid ,Discs 50 mm
What is this article?
Membrane filter Cellulose nitrate ,0.45 µm, sterile, black, grid ,Discs 50 mm is the article on this page. Luminix Health distributes Hahnemühle for laboratory use. It sits in Filter paper, inside Filtration, in Lab consumables.
Filter paper is a cellulose sheet of a stated retention and speed. Qualitative paper clarifies. Quantitative, ashless paper is for a precipitate that will be weighed or ashed, because the paper itself leaves almost no ash. The diameter has to match the funnel.
Filtration holds back what is larger than the pores and lets the rest through. Paper is the ordinary laboratory filter. A membrane has a stated pore size and a polymer that must survive the solvent. A syringe filter is that membrane in a housing on a syringe. Glass fibre takes a higher dirt load. Ultrafiltration holds back macromolecules and passes salts. The pore size, the chemical compatibility and the volume are the three choices. Laboratory apparatus around filtration is indexed under ISO laboratory apparatus.
