Description
KWS ground joint grease hard in a 30 ml tin is a specialised lubricant formulated for sealing and lubricating ground glass joints in laboratory glassware. The hard consistency creates a durable film that enables smooth assembly and separation of conical joints while forming an effective barrier against vacuum loss or vapour escape. With a content of 30 ml presented in convenient tin packaging, the grease supports precise application during distillations, extractions, organic synthesis and vacuum work. This product type KWS from manufacturer IDL GmbH belongs to the essential Schlifffett category used throughout research and teaching laboratories. A thin coating applied to the ground surfaces prior to joining protects expensive glassware from seizure and helps maintain airtight connections on flasks, condensers, adapters and reactors. The controlled hard grade is preferred where a firmer, longer-lasting seal is required under typical laboratory temperature variations. Packaged as one unit, it offers ready-to-use convenience for routine maintenance of jointed apparatus and contributes to experimental integrity across organic, inorganic and physical chemistry workflows.

Questions about KWS joint grease without silicone, jar of 30 ml
What is this article?
KWS joint grease without silicone, jar of 30 ml is the article on this page. Luminix Health distributes IDL GmbH for laboratory use. It sits in Sample containers & jars, inside Bottles & containers, in Labware.
A sample container or jar is the vessel the sample travels in, with a closure that survives the trip. The volume and the liner decide whether the sample that arrives is the sample that was taken.
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.
