Description
Filter form disc with inner diameter 40 mm and outer diameter 100 mm is a natural rubber sealing component intended for laboratory filtration assemblies such as Büchner funnels and nutsche filters. Manufactured from natural rubber (NR) in red colour with a hardness of 40 Shore A, the disc provides a flexible, conforming seal between glass or porcelain filter funnels and receiving flasks. The pack contains 10 pc(s) and each disc has a net weight of 0,05312 kg. This accessory from manufacturer Deutsch & Neumann is commonly used in vacuum filtration setups to ensure airtight contact and prevent leakage during suction filtration of precipitates or suspensions. The 40 Shore A hardness balances elasticity and durability for repeated laboratory handling. Suitable for standard filter apparatus requiring a 40 mm inner and 100 mm outer diameter gasket, the disc supports reliable sealing in chemical, pharmaceutical and analytical laboratories performing solid–liquid separations under vacuum or reduced pressure. Its form-stable rubber construction helps maintain consistent contact pressure across the sealing face during routine filtration work.

Questions about Filterformscheibe inner diameter 40, outer diameter 100 mm Naturkautschuk (NR),
What is this article?
Filterformscheibe inner diameter 40, outer diameter 100 mm Naturkautschuk (NR), is the article on this page. Luminix Health distributes Deutsch & Neumann for laboratory use. It sits in Other lab tools & accessories, inside Tools & accessories, in Labware.
This shelf is the bench tools that do not belong to a narrower rack: odd holders, small aids, pieces that complete a setup. The useful check is what the tool touches, and whether that contact adds a contaminant.
The small tools of the bench are what the hand actually holds: a spatula for a powder, forceps for an object that must stay clean, a brush for a narrow neck, a desiccator when a dried sample must not take up water again. None of these reads a measurement. They keep the measurement possible. The apparatus around them is listed under ISO laboratory apparatus.
