Description
BOLA filter membranes Ø 25 mm with a pore size of 5 µm are circular discs made of microporous PTFE for laboratory filtration work. Each membrane has a thickness of 0,2 mm and offers a filter area of 490 mm², giving a compact format suited to small holders and standard 25 mm filtration setups. The microporous polytetrafluoroethylene structure supports chemical resistance typical of PTFE while providing a defined pore size for particle retention and fluid clarification tasks. Supplied in a practical pack of 10 pieces, the membranes are ready for routine sample preparation, solvent handling, and general lab filtration where a 5 µm rating is required. Dimensions are clearly specified as membrane diameter 25 mm, pore size 5,00 µm, thickness 0,2 mm and filter area 490 mm², so selection against apparatus and process needs is straightforward. These BOLA membranes from manufacturer Bohlender form part of a broader size range for matching diameter and porosity to the application. Net weight per pack is approximately 0,003 kg. Further diameters and pore sizes are available under related article numbers in the same series, allowing consistent material choice across different filtration scales in research and quality-control laboratories.
This article is part of Membrane filters, in Filtration.

Questions about BOLA Filtering Membranes, Ø 25mm 5µm t=0,2mm PU=10pcs. Made of microporous PTFE
What is this article?
BOLA Filtering Membranes, Ø 25mm 5µm t=0,2mm PU=10pcs. 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.
