Description
Ground joint grease, medium-viscosity, is a silicone-based lubricant formulated for sealing and lubricating ground glass joints in laboratory glassware. Based on Baysilon silicone, this medium-viscosity grade offers a practical balance between ease of application and durable film formation on conical and spherical joints. The 35 g pack is convenient for everyday bench use, enabling controlled dispensing while supporting vacuum-tight connections and reducing the tendency of joints to seize during repeated assembly and disassembly. Suitable for organic synthesis, distillation, analytical work and general laboratory glassware setups, the grease helps maintain reliable seals under typical ambient laboratory conditions. This product from manufacturer Witeg is intended as a routine consumable for research, quality-control and teaching laboratories that rely on classic ground-joint apparatus. Its silicone character provides the handling properties expected for standard joint lubrication tasks. With a net weight of 0,039 kg, each unit is compact and easy to store beside the glassware. Medium-viscosity ground joint grease remains a staple accessory for preserving glassware integrity and operational convenience in daily laboratory practice.
This article belongs on Ground-joint glassware (other), in Distillation & extraction glassware.

Questions about Grease f. joints middle viscous
What is this article?
Grease f. joints middle viscous is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Ground-joint glassware (other), inside Distillation & extraction glassware, in Labware.
This is ground-joint glassware that is not a head, a condenser or a Soxhlet: receivers, blank joints, odd adapters. A ground joint is named by the wide end and the length, such as 29/32. Mismatched joints do not seal, even with grease.
Distillation separates liquids by boiling point. A condenser turns the vapour back into liquid: Liebig, coil and cold-finger shapes differ in how much cooling surface they offer. A still head and a column sit between the flask and the condenser. A Soxhlet extractor washes a solid again and again with the same solvent. Ground joints have a standard size, and the joint, not the flask, is what has to match. The pieces are indexed under ISO laboratory glassware.
