Description
Glass microfibre filter grade 13430 is a laboratory filtration medium intended mainly for use as a prefilter. Grade 13430 filters are most often employed as prefilters when an initial clarification step is required before finer membrane filtration. Available in a pack of 50 pieces, this format supports routine sample preparation and general laboratory filtration work. The pack has a net weight of 0,370 kg and a gross weight of 0,400 kg. These glass microfibre filters from manufacturer Sartorius provide a practical prefiltration choice for analytical and preparative applications where particulate load should be reduced ahead of subsequent stages. Originating from Germany, grade 13430 fits laboratory workflows that rely on glass microfibre media as a first filtration step. The filters can be integrated into existing membrane-filter setups whenever a dedicated prefilter grade is needed. Research, quality-control, and process laboratories benefit from a consistent glass microfibre option for everyday prefiltration and sample-handling tasks. The product remains a straightforward choice for standard laboratory filtration sequences that begin with a prefilter stage.

Questions about Glass fiber pre-filter; thick; 142mm;
What is this article?
Glass fiber pre-filter; thick; 142mm; 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.
