glisseal HV

Silicone-free lubricating grease for ground joints, stopcocks and apparatuses.

Application
glisseal is suitable for sealing and lubricating fixed and rotary ground glass joints and for greasing fittings made of plastics and metal.
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 guarantes 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.

Properties
Important properties:
- silicone-free
- withstands vacuum and high vacuum
- excellent thermal stability
- constant lubricating consistency between -40 °C and +250 °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
Please, find the physical data of both glisseal products on the technical datasheet.
