Description
BOLA filter membranes with a diameter of 25 mm and a pore size of 0,2 µm are laboratory filtration discs made from microporous polytetrafluoroethylene (PTFE). Membrane thickness is 0,2 mm and the filter area is 490 mm², offering a compact geometry suited to small-scale laboratory filtration. The microporous PTFE build is part of the BOLA membrane line for use as polymer filter media in the lab. Each pack comprises 10 pieces, which simplifies replenishment for routine work. These membranes from manufacturer Bohlender come with defined dimensional specifications, including the 25 mm membrane diameter and the 0,2 µm pore size. The 0,2 mm thickness supports practical handling during mounting in matching holders or assemblies. Net weight of the pack is 0,003 kg. Additional sizes are listed within the wider BOLA filter membrane series. Combining microporous PTFE, a controlled 0,2 µm pore rating, a standardised 25 mm diameter and a 10-piece pack, these discs serve laboratory filtration tasks that require PTFE media in this intermediate pore-size format.
This article is part of Membrane filters, in Filtration.

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