Beschreibung
Nalgene™ Water Quality Membrane is a sterile gridded membrane filter for laboratory water quality testing. It has a membrane diameter of 90 mm and is specified as a prefilter-type membrane with glass-fibre material and a glass membrane construction. The gridded membrane surface supports clear orientation and documentation when retained material is inspected after filtration. Product information positions Nalgene water quality membranes for official water quality testing workflows, and this article is packed as a case of 100 pieces for continuous analytical use. The 90 mm round-filter format matches common holder geometries used in environmental monitoring and quality-control laboratories. These membranes from manufacturer Thermo Scientific - Laboratory Plastics help standardise serial sampling where sterile, ready-to-use filters reduce bench preparation time. Gross weight is 0,136 kg with a packaging volume of 0,003 m³, so storage beside manifolds and vacuum flasks remains modest. Deploy the gridded 90 mm water quality membrane within your validated filtration method, confirming holder fit, sample volume and process conditions before routine runs in teaching, process or environmental laboratories that rely on consistent prefilter performance day after day.
This article is part of Membrane filters, in Filtration.

Questions about Nalgene™ Membrane and Prefilter Disks
What is this article?
Nalgene™ Membrane and Prefilter Disks is the article on this page. Luminix Health distributes Thermo Scientific - Laboratory Plastics for laboratory use. It sits in Membrane filters, inside Filtration, in Verbrauchsmaterialien.
A membrane filter is the disc itself, without a syringe housing. Pore size, polymer and diameter are the specification, and the disc has to sit in a holder. Gridded membranes are for counting colonies. A membrane and a filter paper of the same diameter are not interchangeable.
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.
