Description
BOLA filter membranes, Ø 90 mm with a pore size of 5 µm, are laboratory discs manufactured from microporous PTFE. Each membrane is 0,2 mm thick and offers a filter area of 6362 mm², consistent with the 90 mm diameter format used in many laboratory filtration setups. The microporous PTFE material is suited to filtration applications that benefit from the chemical resistance typical of this polymer class, while the 5 µm pore size defines the retention characteristic of the medium. Supplied in packs of 10 pieces, the membranes support continuous laboratory work, method transfer and spare stock for shared filtration stations. Stated values for diameter, pore size, thickness and filter area allow straightforward comparison with holder dimensions and process needs. Related BOLA PTFE membrane sizes are listed under further article numbers in the same series. Available from manufacturer Bohlender, these discs serve as ready-to-use consumables for liquid filtration on the bench. Pack net weight is 0,0206 kg. Clear geometric and pore-size data assist reliable selection within standard 90 mm filtration hardware.

Questions about BOLA Filtering Membranes, Ø 90mm, 5µm, t=0,2mm, PU=10pcs. Made of microporous PT
What is this article?
BOLA Filtering Membranes, Ø 90mm, 5µm, t=0,2mm, PU=10pcs. Made of microporous PT 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.
