Description
Seal, PTFE for VF8 is a dedicated sealing component for laboratory vacuum filtration systems of the VF8 series. Made from polytetrafluoroethylene (PTFE), the seal is intended to provide a chemically resistant sealing interface within filtration assemblies used in routine sample preparation and solid–liquid separation work. It belongs to the accessory range for vacuum filtration equipment and Witt-type filtration apparatus, where a reliable seal between glassware or filter holders is essential for stable vacuum operation. Supplied as a single piece from manufacturer Witeg, this PTFE seal is suited to replacement or maintenance of VF8 filtration setups in analytical, quality-control and research laboratories. PTFE is widely chosen in laboratory filtration hardware because of its broad chemical resistance and suitability for contact with many aqueous and organic media encountered in filtration workflows. The component supports consistent assembly of the filtration train and helps preserve vacuum integrity during use. Pack size is one piece, ready for installation on compatible VF8 hardware.
This article is part of Membrane filters, in Filtration.

Questions about Gasket, PTFE, for V8
What is this article?
Gasket, PTFE, for V8 is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Membrane filters, inside Filtration, in Lab consumables.
A membrane filter is the disc itself, without a syringe housing. Pore size, polymer and diameter are the specification, and the disc has to sit in a holder. Gridded membranes are for counting colonies. A membrane and a filter paper of the same diameter are not interchangeable.
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.
