Description
PTFE centering ring spare part for vacuum filter units is a dedicated replacement component for laboratory filtration assemblies. Designed as a centering ring in PTFE, it supports correct alignment and seating within compatible vacuum filter hardware used in routine sample preparation and separation workflows. This spare part helps maintain reliable filter-unit geometry when original rings wear, deform, or require renewal during service. Supplied as a single piece and weighing 0,015 kg, it is straightforward to stock as a maintenance item beside vacuum filtration stations. The component fits the filtration devices and filter holders segment of labware used for solid–liquid separation and related sample work-up. Offered from manufacturer Cytiva, the PTFE centering ring is intended for laboratories that keep vacuum filter units operational with genuine-style spare parts rather than improvised substitutes. Use it when restoring centering function on vacuum filter units that specify this PTFE ring type, ensuring the filter path remains properly guided during filtration steps in research, quality control, and general analytical environments.

Questions about Spare part for vacuum filter units, PTFE-centering ring, 1 unit(s)
What is this article?
Spare part for vacuum filter units, PTFE-centering ring, 1 unit(s) is the article on this page. Luminix Health distributes Cytiva for laboratory use. It sits in Bottle-top & vacuum filtration units, inside Filtration, in Lab consumables.
A bottle-top filter or a vacuum filtration unit sits on a bottle and pulls a liquid through a membrane under vacuum. Pore size and membrane are the same choice as a syringe filter, at a larger area. A sterile unit is a stated claim. The bottle neck has to match.
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.
