What is N grease?

Apiezon N Grease is silicone-free and widely recognised and recommended as the cryogenic vacuum grease of choice. This cryogenic grease is specially formulated to exhibit craze-free performance characteristics at low temperatures and withstand frequent cycling between cryogenic temperatures as low as -273°C and +30°C.

What is apiezon grease?

Apiezon L Grease 25 G Tube is a silicone-and halogen-free ultra high vacuum grease suitable for use in scientific and industrial applications. Apiezon L Grease is an ultra high vacuum grease which exhibits an extremely low vapor pressure of 7 x 10-7 Torr at 20 degrees Celsius.

How do I remove apiezon grease?

Apiezon for cryogenics applications Any residues of grease can be washed away with warm soapy water or by using any aromatic hydrocarbon solvent (toluene, xylene). For a more environmentally friendly solvent, we recommend limonene. They cannot be cleaned using alcohols (ethanol, IPA) or ketones (acetone, MEK).

What is vacuum grease made of?

Dow Corning® High-Vacuum Grease is a stiff, nonmelting silicone lubricating material that maintains its consistency from -40 to 204°C (-40 to 400°F). It is used in applications similar to those for Dow Corning® Stopcock Grease, and is the recommended replacement for that product.

What is vacuum grease used for?

Vacuum grease is a lubricant with low volatility and is used for applications in low pressure environments. Lubricants with higher volatility would evaporate, causing two problems: They would not be present to provide lubrication. They would make lowering the pressure below their vapor pressure difficult.

How do you get vacuum grease off glasses?

Piping hot soapy water might do the trick. I’ve had good luck getting silicone oil off of glassware using a fair bit of Liquinox in the hottest water I could get – soak it for 10 min or so, then go to scrubbing as much as you can.

How does vacuum grease work?

How do you use high vacuum grease?

How To Grease Vacuum Joints

  1. Use a Pea-sized Dab of Grease. Many individuals do not know, and this is one of the main problems that can cause a leak when performing vacuum distillation.
  2. Evenly Spread the Grease.
  3. Gently Insert the Glassware.
  4. Twist the Joint Back and Forth Carefully.
  5. Check your work!

How do you use vacuum grease?

Why is grease used in distillation?

Greasing the joint makes it airtight and prevents the solvent from evaporating out (also prevents air and moisture from getting in if you need to be concerned about that).

What is the best solvent to dissolve grease?

Alcohol. Another method of dissolving stubborn kitchen grease is to use isopropyl alcohol. Isopropyl alcohol works in a similar manner to water-displacing lubricants. It breaks up the grease into smaller particles and surrounds it with alcohol molecules, in effect dissolving the grease.

What is the suitable solvent of grease?

Solutes Solvents used
Chlorophyll Methylated spirit
Grease Petrol
Rust Oxalic acid
Rubber Benzene

Is it OK to use Apiezon grease type N?

Note: Apiezon Grease Type N is not recommended for use with delicate materials such as glass-to-glass joints. The risk of fracture is high and therefore type N is unadvised.
