Description
Funnel 500 ml (spin-lock), PES for LF5/5a is a polyethersulfone laboratory funnel designed for vacuum filtration with LF5 and LF5a apparatus. Featuring a spin-lock connection, this 500 ml funnel supports secure attachment within Witt-type filtration systems used for analytical and preparative sample processing. The PES construction suits routine laboratory filtration workflows where chemical resistance and dimensional stability are required. Supplied as a single unit with a net weight of 0,148 kg, the funnel integrates into modular vacuum filtration equipment as a primary sample-receiving component. It is offered by manufacturer Witeg and is intended for use with compatible LF5/LF5a filtration setups. The spin-lock design facilitates reliable coupling during operation under reduced pressure, helping maintain a stable filtration assembly. Suitable for research, quality-control and general laboratory environments, this funnel contributes to flexible Witt filtration apparatus configurations. Packaged as 1 pc, it serves as a practical replacement or expansion part for laboratories working with 500 ml PES funnel capacities on LF5 and LF5a systems.
This article is part of Membrane filters, in Filtration.

Questions about Funnel 500ml LF5 (Spin-lock), PES for LF5/5a
What is this article?
Funnel 500ml LF5 (Spin-lock), PES for LF5/5a is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Membrane filters, inside Filtration, in Consommables.
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.
