Description
Glass microfibre filter / Grade 13400 is a laboratory glass-microfibre grade used most often as a pre-filter. The media provides an upstream depth stage that captures particulates before finer membrane filtration, helping protect downstream filters during clarification of laboratory samples and process liquids. Supplied in a pack of 100 pc(s), with a net weight of 0,077 kg and gross weight of 0,080 kg, the format supports frequent pre-filtration work without constant reordering. These Grade 13400 filters from manufacturer Sartorius are non-sterile and intended for general laboratory pre-filter applications rather than final sterile barrier use. Produced in Germany (Lower Saxony origin region), they fit standard lab consumable inventories for multi-step filtration trains. Deploy Grade 13400 ahead of membrane filters when sample loads require a robust glass-microfibre pre-stage, or when extending membrane life during routine clarification is a priority. The pack quantity suits shared laboratory stocks and method-development benches that rely on consistent pre-filter performance across many runs.
This article is part of Glass & quartz fibre filters, in Filtration.

Questions about GFpre-filter;80mm;100pc
What is this article?
GFpre-filter;80mm;100pc 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.
