Description
Glass fibre (GF) pre-filter is a depth pre-filter intended for larger quantities in fully filterable clarification and sterile filtration. The glass-fibre media acts as a protective upstream stage, retaining particulate load before final membrane steps and supporting consistent flow through multi-stage laboratory filtration trains. Packaged as 1 pc with a net weight of 0,040 kg and matching gross weight of 0,040 kg, the unit is straightforward to stock and deploy in routine clarification work. This pre-filter from manufacturer Sartorius is positioned for depth pre-filtration duties where higher solids challenge would otherwise shorten the life of sterilizing-grade membranes. Originating from Germany, it integrates cleanly into standard lab material workflows for clarification of fully filterable liquids ahead of sterile filtration. Use it to extend membrane service intervals, stabilize throughput on larger sample volumes, and maintain process reliability when a dedicated glass-fibre depth stage is required before final filtration. The format suits single-unit replenishment of pre-filter inventories without excess packaging bulk.
This article is part of Glass & quartz fibre filters, in Filtration.

Questions about GFpre-filter;79mmx79mm;50pc
What is this article?
GFpre-filter;79mmx79mm;50pc is the article on this page. Luminix Health distributes Sartorius for laboratory use. It sits in Glass & quartz fibre filters, inside Filtration, in Lab consumables.
Glass-fibre and quartz-fibre filters are depth filters with a high dirt load, used for air sampling, for total suspended solids and in front of a membrane. They have no sharp pore-size cutoff the way a membrane does. Binderless grades matter when the filter will be weighed or heated.
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.
