PTFE membrane filter discs hydrophobic 142 mm, 0,45 µm are unsupported hydrophobic PTFE membrane filters intended for laboratory use. These circular filter discs measure 142 mm in diameter and are manufactured with a defined pore size of 0,45 µm. The membranes are produced without any support structure, resulting in a pure PTFE disc that retains the inherent hydrophobic character of polytetrafluoroethylene. Packaged in units of 50 pieces, the product is available from manufacturer Berrytec for routine laboratory filtration tasks. The absence of a backing layer distinguishes these discs from laminated membrane filters and keeps the filtration medium as pure PTFE throughout. With a pack net weight of 0,16 kg, the discs are compact and convenient for storage and handling in the laboratory. Diameter, pore size and hydrophobic PTFE construction without support structure constitute the essential product identity. Laboratories requiring plain hydrophobic PTFE membranes in the 142 mm format will find these discs a straightforward choice matching the stated specifications.
This article is part of Sintered glass filter plates & discs, in Filtration.

Questions about PTFE hydrophobic membrane disc filter 142mm, 0,45µm
What is this article?
PTFE hydrophobic membrane disc filter 142mm, 0,45µm is the article on this page. Luminix Health distributes Berrytec for laboratory use. It sits in Sintered glass filter plates & discs, inside Filtration, in Verbruiksartikelen.
A sintered glass filter is a disc of fused glass particles with a porosity grade, often 0 to 5, from coarse to fine. It is cleaned and reused. The porosity number, not a micrometre guess, is the specification. Hydrofluoric acid and strong alkali attack the glass.
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.
