Glisseal HV High Vacuum  High Temperature Grease for Glass Joints supports +320C made in Switzerland (like Rolex)

Supports High Temperatures perfect for hot condenser for Short Path Distillation

High Vacuum High Temperature Glass Joints grease +320C vacuum distillation grease

Due to its excellent thermal stability coupled with a constant consistency and low vapour pressure glisseal can be used to lubricate vacuum, high vacuum and reflux distillation equipment. Ground joints and stirring equipment can be sealed gastight, but can be taken apart without problems even after prolonged use. Since glisseal is inert against most inorganic and organic compounds it guarantees accurate analytical results. Glass apparatuses can be repaired without difficulties, since no interfering silicone residues are present. glisseal is also suitable for solving demanding greasing problems in the fine mechanical and optical industries. Important notice: oxygen valves must not be greased with glisseal.
