Description
Glass fibre (GF) pre-filter is a depth prefilter designed for processing larger sample volumes during fully filterable clarification and sterile filtration. The glass fibre media retains coarser particles early in the filtration train, protecting subsequent membranes and extending their service life. Offered as a single piece, this prefilter from manufacturer Sartorius is intended for laboratory applications that demand efficient particulate reduction before final sterile or analytical steps. Depth-filtration characteristics make the product suitable for clarification of liquids containing higher solid loads. The format supports standard filter holders used in research, quality control and process development. Consistent glass fibre construction ensures reproducible prefiltration performance across repeated runs. Laboratories select this GF pre-filter when larger quantities must be prepared for sterile filtration while maintaining high overall throughput and filter integrity.
This article is part of Glass & quartz fibre filters, in Filtration.

Questions about GFpre-filter;49mmx49mm;50pc
What is this article?
GFpre-filter;49mmx49mm;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.
