Description
Glass microfibre filter grade 13400 is a non-sterile glass microfibre filtration medium used mainly as a prefilter in laboratory practice. Grade 13400 filters are most often employed upstream of finer filtration stages to capture coarser particles during sample preparation and routine clarification. This configuration is supplied in a pack of 500 pieces from manufacturer Sartorius and is listed under laboratory materials for general filtration use. Each pack has a net weight of 0,157 kg and a matching gross weight of 0,157 kg. The filters are intended for room-temperature storage, are non-sterile, and have a shelf life of 1825 days. Manufactured in Germany (Lower Saxony), grade 13400 glass microfibre filters provide a practical bulk prefiltration option for laboratories that prefer glass microfibre media before membrane filtration or further analytical steps. Their established use as prefilters supports consistent upstream particle retention in everyday laboratory workflows without additional performance claims beyond the stated grade and application.
This article is part of Glass & quartz fibre filters, in Filtration.

Questions about GFpre-filter;42mm;500pc
What is this article?
GFpre-filter;42mm;500pc 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.
