Description
Glass microfibre filter grade 13400 is a laboratory glass microfibre filter medium that is most often used as a prefilter. This grade supports preparatory filtration steps in analytical and research laboratories where an initial clarification stage is required. Packaged as 500 pieces per unit, the format is convenient for laboratories that process multiple samples and need a ready stock of prefilters. The pack has a net weight of 0,170 kg and a gross weight of 0,170 kg. Grade 13400 filters are non-sterile and therefore intended for general laboratory filtration rather than sterile protocols. Available from manufacturer Sartorius, these glass microfibre filters belong to the laboratory materials assortment used in sample preparation sequences. They are selected when a glass microfibre prefilter is specified ahead of subsequent filtration stages. Country of origin is India. Grade 13400 remains a practical choice for routine prefiltration duties across quality control, research, and teaching laboratories that rely on glass microfibre media for everyday sample handling.
This article is part of Glass & quartz fibre filters, in Filtration.

Questions about GFpre-filter;47mm;500pc
What is this article?
GFpre-filter;47mm;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.
