Description
BOLA filter membranes, Ø 47 mm with a pore size of 10 µm, are laboratory filtration discs made from microporous PTFE. Each membrane has a thickness of 0,2 mm and a filter area of 1732 mm², giving a defined geometry for use in standard 47 mm holders. The microporous PTFE structure is intended for filtration steps where chemical resistance of the membrane media is required. These membranes are supplied as a pack of 10 pieces, supporting consistent replacement and parallel sample work in analytical and preparative laboratory settings. Pore size, diameter and thickness are specified to help match the membrane to the intended particle retention and flow conditions. Further sizes in the same BOLA PTFE membrane family are referenced under related article numbers. Produced by manufacturer Bohlender, the discs form a practical consumable for routine filtration of liquids and solvents on the bench. Pack net weight is 0,05 kg. Clear dimensional data for diameter, pore size, thickness and filter area facilitate selection alongside existing filtration hardware and protocols.
This article is part of Membrane filters, in Filtration.

Questions about BOLA Filtering Membranes, Ø 47mm 10µm t=0,2mm PU=10 pcs Made of microporous PTFE
What is this article?
BOLA Filtering Membranes, Ø 47mm 10µm t=0,2mm PU=10 pcs Made of microporous PTFE is the article on this page. Luminix Health distributes Bohlender 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.
