Description
Protective sleeves for aspirator bottles 100 ml, rubber are natural-rubber adapters designed for filtering and aspirator flasks in vacuum filtration setups. Their special geometry keeps the funnel and flask centred during assembly and use, improving mechanical stability of the filtration train. Beyond alignment, the sleeves provide comprehensive impact protection by cushioning shocks that could otherwise damage glassware at the flask rim or funnel neck. They also create a clean, continuous seal between the flask rim and the funnel neck, supporting reliable vacuum integrity during solid–liquid separations. Suitable for routine laboratory filtration work with 100 ml aspirator bottles, these protective sleeves from manufacturer ISOLAB Laborgeräte help reduce breakage risk and maintain a tidy interface between glass components. The natural rubber construction offers the flexibility needed for repeated mounting and demounting while remaining compatible with standard laboratory filtration assemblies used in analytical and preparative workflows.

Questions about protective collars - rubber - for filter flask - 100ml
What is this article?
protective collars - rubber - for filter flask - 100ml is the article on this page. Luminix Health distributes ISOLAB for laboratory use. It sits in Canisters & jerrycans, inside Bottles & containers, in Labware.
A canister or jerrycan holds litres, not millilitres, and it is shaped to be carried and to pour. The material has to survive the liquid for the whole time the can sits in the store.
A laboratory bottle is a closed container with a stated volume and a neck that takes a cap, a stopper or a dispenser. Borosilicate glass is the choice when the liquid is a solvent, or when the bottle will be heated or autoclaved. Polyethylene and polypropylene are the choice when the bottle must not shatter, or when hydrofluoric acid would attack glass. A narrow mouth pours. A wide mouth is for powders and for reaching the bottom. Laboratory ware of this kind is indexed under ISO laboratory glassware. Traceable volume sits with the BIPM and NIST Physical Measurement.
