Description
Glass microfibre filter grade 13400 is a laboratory filtration medium most often used as a prefilter. Filters of this grade are typically employed ahead of finer membranes to retain larger particles during sample preparation and clarification work. Supplied in a pack of 500 pieces, the grade 13400 glass microfibre filters from manufacturer Sartorius support high-throughput prefiltration tasks in analytical, research and quality-control laboratories. The glass microfibre construction is intended for the initial filtration step that precedes more selective membrane filtration. With a net weight of 0,104 kg and a matching gross weight of 0,104 kg, the pack offers a compact bulk format for frequent laboratory use. Laboratories select this grade when a dedicated prefilter layer is required before membrane filtration or related procedures. The product is non-sterile and fits standard laboratory filtration practices for initial particle removal from liquid samples. Grade 13400 glass microfibre filters therefore provide a practical prefiltration option for scientific applications that start with a clarification stage. This larger pack size suits workflows that consume prefilters regularly within multi-step sample processing sequences.

Questions about GFpre-filter;25mm;500pc
What is this article?
GFpre-filter;25mm;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.
