Description
PP membrane filter discs 25 mm, 0,45 µm are polypropylene membrane filters intended for general laboratory filtration work. Each disc has a diameter of 25 mm and a pore size of 0,45 µm, providing dependable particle retention and sample clarification for analytical and preparative tasks. The polypropylene construction delivers chemical compatibility with many aqueous and organic media used in research, quality-control and process laboratories. Offered in packs of 100 pc(s) from manufacturer Berrytec, the discs integrate readily into syringe-filter holders, vacuum filtration systems or other standard laboratory equipment. Pack net and gross weight is 0,025 kg; packaging volume is 0,000054 m³ with outer dimensions 0,015 m × 0,06 m × 0,06 m, supporting efficient storage and logistics. These membrane discs constitute a practical everyday consumable for sample preparation, solvent filtration and particulate removal steps that require a 0,45 µm pore rating. Their consistent geometry and material properties allow straightforward incorporation into established laboratory protocols without special adaptation.

Questions about PP membrane disc filter 25mm, 0,45µm
What is this article?
PP membrane disc filter 25mm, 0,45µm is the article on this page. Luminix Health distributes Berrytec for laboratory use. It sits in Membrane filters, inside Filtration, in Lab consumables.
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.
