Glisseal HV High Temperature & Vacuum Grease 320C

Glisseal HV High Temperature & Vacuum Grease for Glass Joints 320C

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.

– silicone-free - doesn't freezer glass joints - keep your glass safe – withstands vacuum and high vacuum – excellent thermal stability – constant lubricating consistency between -40 °C and +320 °C – no dripping point – chemically stable against most acids, alkalis and gases – insoluble in water and low molecular mono- and polyhydric alcohols such as ethanol, ethylene glycol, glycerine etc. – can be dispersed in low molecular ketones, esters, amines, hydrocarbons, benzene derivatives, higher fatty acids, fatty acid esters and ethers glisseal lubricating grease for laboratory equipment is available in two qualities – glisseal N „normal quality“ - for applications in normal ­ conditions and under vacuum – glisseal HV „high vacuum“ - specifically suitable for ­ applications under high vacuum
