msdsarrow12Apiezon Grease; Type L

Grease L is a petroleum hydrocarbon grease, containing no additives. Very low vapor pressure (@20°C of 8x10-11 torr), high vacuum grade. Type L is widely used in the stationary phase of gas liquid chromatography, and may be used on all ground joints in a vacuum system (not for stopcocks). Its solubility is as follows: in Ethanol at 20°C-0.003%; 60°C-0.005%; 100°C-0.011%; 150°C-0.011%. Grease L softens and melts at about 47°C and it is not recommended for joints where temperatures exceed more than 30°C in use. Grease T is recommended for these higher temperatures.

60702 Apiezon Grease L 25g tube 96.00 Add to Cart
msdsarrow12Apiezon Grease; Type M

Similar to grease type L, but it contains more wax. Grease M has an estimated vapor pressure @ 20°C of 2x10-9 torr, higher than Type L. Type M is recommended for applications where a grease of moderately low vapor pressure is required; such as for sealing ground joints on the backing side of oil diffusion pumps.

60700 Apiezon Grease M 25g tube 60.00 Add to Cart
msdsarrow12Apiezon Grease, Type N

Similar to Type L and Type M, but Type N grease has a special additive which gives it a tenacious, rubbery consistency and provides an extra cushioning effect which absorbs vibrations in equipment, making N grease invaluable in fragile glass to glass joints, like burette taps, which continually risk fracture. Grease N is widely recognized and recommended as the cryogenic vacuum grease of choice.

60701 Apiezon Grease N 25g tube 152.00 Add to Cart
msdsarrow12Apiezon Grease, Type H

Type H grease is designed for high temperatures (-10 to +240°C) in a wide range of applications in both science and industry. With good "friction", grease H is ideal for use with laboratory glassware, but combined with properties of high thermal conductivity, it is the perfect choice for the electronics and space industries where heat sink media require adhesion.
Grease H is a filled hydrocarbon which exhibits excellent thermal conductivity, and strong absorption properties. The capability to absorb greasy or chemical impurities on metal and glass surfaces is a value "tool" required by electronic industries.

60703 Apiezon Grease H 25g tube 134.00 Add to Cart
msdsarrow12Apiezon Grease; Type T

Type T is designed for lubricating glass taps and for general purposes. Has a melting point of 125°C and has an estimated vapor pressure @ 20°C of 5x10-9 torr. Although type T is useful at higher temperatures, it can also be used at ambient temperatures.
Temperature range: 0-120°C.

msdsAP100 Greasearrow12Apiezon Grease, Type AP100

Apiezon AP100 Grease is a silicone-free vacuum grease and lubricant. Containing PTFE, AP100 exhibits extremely high levels of lubricity and has been shown to provide eight times the level of lubrication offered by standard, petroleum-based lubricating greases.

Apiezon AP100 is designed for use at ambient temperatures (generally between 10 to 30°C / 50 to 86°F). If you are looking for a grease capable of performing at higher temperatures, Apiezon AP101 or Apiezon H Grease may be more appropriate.

Benefits

  • Has anti-seize properties, making it an effective protector and lubricant in ultra-high vacuums
  • Exhibits extremely high levels of lubricity
  • Demonstrates an extremely low vapour pressure of 7 x 10-11 Torr at 20°C
  • Recommended for use at ambient temperatures
  • Does not suffer from contamination problems associated with silicone based greases such as "creep" or "carry over"
  • Easy to clean and remove using hot water and an aqueous glassware detergent, hydrocarbon or chlorinated solvents

Applications

The unique properties of Apiezon AP100 lubricating vacuum grease mean it is frequently used to protect stepping motors and gearboxes from corrosion and abrasion, particularly when they are subjected to high load conditions. AP100 is also used to prevent seizure in stopcocks, taps and small metal fastenings.

The creep resistance of Apiezon AP100 benefits scientific and semiconductor users alike. AP100 helps to increase the accuracy of analytical techniques and improve yields in semiconductor manufacture by contamination avoidance. In addition, AP100 is used for surface coating applications where silicone contamination can lead to poor surface adhesion and incomplete coating defects.

msdsarrow12Apiezon Grease, Type AP101

Type 101 is an excellent general purpose, hydrocarbon grease, which is intended for a variety of industrial and scientific applications.

  • Anti-Seize Properties: The AP 101 contains "PTFE" which confers superior anti-seize properties providing long lasting lubrication and ensuring smooth operation of stop cocks and taps. The value of AP 101 anti-seize properties are not limited to laboratory or glassware use, but are equally effective when used on metal equipment which may be subject to seizure or corrosion
  • Non silicone Grease: Being hydrocarbon based AP 101 does not suffer from the problems of "creep" or "carry over" which is traditionally associated with silicone greases. It reduces sample contamination and the risk of interference in analytical techniques such as infra-red and mass spectrometry
  • Solvent resistant: Both "PTFE" and the lithium stearate gel base in AP 101 are insoluble in most solvents. They ensure that AP 101 shows resistance to water, alcohols, ketones and esters. In addition AP 101 resists attack from aqueous acid and alkali solutions, alcoholic alkali solutions and corrosive gases
  • Wide temperature range: It can be used over a very wide range of temperatures, possessing its optimum consistency over the -15 to +150°C temperature range, but is usable down to -40°C and, for limited periods, up to +180°C
  • Under vacuum: AP 101 exhibits good vacuum properties, down to 10-4 torr
  • Easily remove AP 101 by wiping it with a soft cloth. Any residues of grease can be washed away with an aqueous glassware detergent

Text Box:  arrowTorrLube® Vacuum Oil and Lubricant

TorrLube® vacuum lubricants are manufactured to perform better than any other vacuum grease or oil available.

  • TorrLube® has no non-metal solids, e.g. silicone ball filters
  • TorrLube® has high thermal conductivity to minimize temperature difference between surface exposed to heat flux and heat sink surface
  • TorrLube® is extremely stable up to 350°C
  • TorrLube is 500 cSt oil at 40°C. TorrLube® has high viscosity so that no fluid flows out between the solid surfaces

TorrLube® Oil is an extremely pure PFPE (Perfluoropolyalkether ) blend which is thoroughly distilled and then filtered through a submicron screen. TorrLube® Oil has the ability to withstand thermal expansion and contraction as well as chemical and mechanical stress, while still maintaining consistent viscosity. These properties make TorrLube® the ideal lubricant for bearings, automated slides, and screws that have a tendency to gall or cold weld while working under extreme conditions.

Text BoxTorrLube® Extreme Grease is white, odorless, nonflammable, and chemically inert products based on TorrLube® Oil and the most advanced PTFE thickener available. It does not contain Sodium or Iron.  TorrLube® Extreme Grease remains stable and will not break down under mechanical stress and lose its ability to hold TorrLube® Oil. TorrLube® Extreme Grease helps prevent sticking, jumping, and mechanical noise, securing smooth, controlled movement.

TorrLube in 1cc syringe – Each syringe contains 1 cc of TorrLube® lubricant with a #22 gauge blunt needle attached for close application. This size is ideal for use in small research units and for maintenance and service tool kits.

Syringes are packaged in a clean room environment and the needles are sealed to prevent contaminant or leakage.
