Description
Joint grease for high vacuum is a specialised laboratory lubricant formulated for ground-glass joints and vacuum apparatus where reliable sealing under reduced pressure is essential. This Schlifffett-type product supports tight, reproducible connections on stopcocks, joints and similar glassware interfaces, helping maintain vacuum integrity during distillation, filtration and other low-pressure workflows. Supplied as a single piece from manufacturer ISOLAB Laborgeräte, the grease is intended for routine laboratory use on ground joints that must remain leak-tight under high-vacuum conditions. Its compact net weight of 0,034 kg and gross weight of 0,039 kg make it convenient for bench-top storage and frequent handling. The formulation is suited to glassware assemblies in analytical, preparative and research laboratories that rely on stable vacuum seals without compromising joint mobility. Use sparingly on clean, dry ground surfaces to achieve an even film that resists creep while preserving the mechanical fit of the joint. Ideal for vacuum lines, rotary evaporators and manifold systems where high-vacuum performance is required.

Questions about joint grease - high vacuum
What is this article?
joint grease - high vacuum is the article on this page. Luminix Health distributes ISOLAB for laboratory use. It sits in Vacuum pumps, inside Pumps, vacuum & evaporation, in Lab instruments.
A laboratory vacuum pump lowers pressure for filtration or evaporation. A diaphragm pump tolerates solvent vapour better than an oil-sealed rotary vane pump, and it reaches a milder vacuum. The ultimate vacuum and the flow, and whether the wetted path survives the solvent, are the choices.
A vacuum pump lowers the pressure above a liquid so it boils at a lower temperature. That is the point of a rotary evaporator: solvent leaves a sample without cooking it. A diaphragm pump or a rotary-vane pump is chosen by the vacuum it reaches and by whether solvent vapour will destroy it. A peristaltic pump moves liquid by squeezing a tube, so the liquid touches only the tube. A barrel pump transfers a larger volume from a drum. The glassware on the evaporator is indexed under ISO laboratory glassware. Solvent identity is on PubChem.
