Beschrijving
Nalgene™ sterile analytical filter units are complete filtration devices for the recovery and growth of microorganisms in quality-control test procedures and for the analysis of water, foods and beverages, raw materials and end products. Each unit uses a cellulose nitrate membrane with a pore size of 0,45 µm and a membrane diameter of 47 mm. The 0,45 µm pore size complies with specifications 909A, B and C of the US APHA Standard Methods, 16th edition, and US EPA certification documentation is enclosed. Units are supplied as a case of 72 pieces, with 12 units per pack, giving laboratories a practical stock level for routine microbiological workflows. Sterile presentation supports aseptic handling from sample preparation through incubation and colony recovery. These analytical filter units from manufacturer Thermo Scientific - Laboratory Plastics suit standardized QC methods where consistent membrane performance and documented method alignment are required. They are well matched to water-quality assessment, beverage testing and incoming-goods inspection that follow established reference protocols.

Questions about Nalgene™ Sterile Analytical Filter Units
What is this article?
Nalgene™ Sterile Analytical Filter Units is the article on this page. Luminix Health distributes Thermo Scientific - Laboratory Plastics for laboratory use. It sits in Bottle-top & vacuum filtration units, inside Filtration, in Verbruiksartikelen.
A bottle-top filter or a vacuum filtration unit sits on a bottle and pulls a liquid through a membrane under vacuum. Pore size and membrane are the same choice as a syringe filter, at a larger area. A sterile unit is a stated claim. The bottle neck has to match.
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.
