Description
PP prefilter, hydrophobic, 30 µm, Ø 47 mm is a polypropylene prefilter disc for laboratory membrane filtration and separation applications. It provides a 30 µm pore size on a 47 mm diameter hydrophobic PP disc compatible with standard laboratory filter holders. Each pack holds 100 pc(s) at a weight of 0,160 kg, supporting efficient stocking for high-throughput or multi-user filtration benches. Polypropylene construction yields a sturdy disc that is straightforward to place and remove during routine work, while the hydrophobic nature matches protocols calling for non-wetting prefilter media. These discs from manufacturer MERCK MILLIPORE form part of the membrane-filter offering used in filtration and separation workflows. Clearly stated pore size and diameter help operators pair the correct disc with written methods and hardware. Laboratories specify this 30 µm, 47 mm hydrophobic PP prefilter when a relatively open polypropylene prefilter is needed for preparatory particle retention or sample clarification. Consistent format labelling reduces selection errors across repeated series.
This article is part of Membrane filters, in Filtration.

Questions about PP prefilter, hydrophobic, Ø 47 mm, pore size 30 µm, 100 unit(s)
What is this article?
PP prefilter, hydrophobic, Ø 47 mm, pore size 30 µm, 100 unit(s) is the article on this page. Luminix Health distributes MERCK MILLIPORE 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.
