Description
Cellulose nitrate membrane filter 0,45 µm is a sterile round filter with a diameter of 47 mm, featuring a black surface with grid for easier colony or particle visualisation. The membrane is made from cellulose nitrate and cellulose mixed ester (CN, MCE) and offers a defined pore size of 0,45 µm for controlled retention in laboratory filtration. Sterile supply means the discs are ready for use where aseptic handling of the filter is required. The contrasting black grid background supports counting and documentation tasks after filtration of aqueous samples. Packaged as 100 pc(s), the product suits regular laboratory throughput with standard 47 mm holders and funnels. These membranes from manufacturer Hahnemühle combine CN/MCE material properties with a practical gridded design for microbiological and quality-control workflows. The round 47 mm format integrates smoothly into established filtration setups, while the marked grid aids consistent evaluation of retained material. Clear pore-size and diameter data help laboratories choose the correct sterile membrane for routine protocols and sample preparation.

Questions about Membrane filter Cellulose nitrate ,0.45 µm, sterile, black, grid ,Discs 47 mm
What is this article?
Membrane filter Cellulose nitrate ,0.45 µm, sterile, black, grid ,Discs 47 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.
