Invoil 705 Diffusion Pump Fluid, 1 Gallon

Meinhard Products Product ID: MC-75008

OEM: 695475008

Invoil 705 Diffusion Pump Fluid is a colorless to straw-colored, singlecomponent fluid designed for ultrahigh vacuum applications in the range of 10-9 to 10-10 torr (untrapped) and 10-11 torr (trapped). The vapor pressure and backstreaming rate of Invoil 705 Diffusion Pump Fluid are so low that use of traps or refrigeration is unnecessary for some ultrahigh and ultraclean vacuum applications. It has the highest phenyl content of all silicone diffusion pump fluids and the best resistance to radiation. High spontaneous ignition temperature makes this fluid ideal for use in humanrated space simulation chambers. 1 Gallon

Inland® 19 Rough Pump Oil, 1 Liter

Meinhard Products Product ID: MC-15101

OEM: 00301-15101

Inland® 19 Rough Pump Oil is ideal for use in all models of vacuum pumps including Alcatel, Edwards, and Welch. Inland 19 utilizes crude stocks known for their durability and fine lubricating qualities. Precision distillation further enhances these characteristics while providing a cleaner, cooler running, longer-lasting oil that in many instances will provide improved pumping cycles. 1 Liter

Inland® 45 Mechanical Pump Oil, 1 Quart

Meinhard Products Product ID: MC-00834

OEM: 6040-0834

Inland® 45 Mechanical Pump Oil permits strain-free cold starts as a result of its low pour point and high viscosity index (its viscosity is lower than that of typical vacuum pump oils at low temperatures). In addition, because it maintains its viscosity at high temperatures, it provides a good seal under full load conditions. Among other properties offered by Inland 45's unique molecular structure are chemical inertness and high-temperature stability superior to those of other high-performance oils, such as white oils; and low vapor pressure (10-7 torr at 25 deg. C). This oil is recommended for use on all H.P. Mass Spectrometers as well as other systems where the best vacuum levels and lowest Mass Spectrometer background are required. 1 Quart

Santovac 5 Diffusion Pump Fluid, 65cc

Meinhard Products Product ID: MC-05002

OEM: 695405002

Santovac 5 Diffusion Pump Fluid is a polyphenyl ether developed from fluids originally produced as lubricants for space vehicles. It has exceptionally low vapor pressure, exceptional thermal stability and a tendency to wet surfaces less readily and "creep" to a lesser extent than is common with most fluids. The fluid is employed for the cleanest high vacuum and ultra high vacuum applications down to less than 10-9 mbar (for example, electron microscopes, mass spectrometers and surface physics studies) where its excellent high vacuum performance and low tendency to migrate into the pump system particularly recommend it. The fluid is chemically stable, non-corrosive, safe and non-toxic at normal operating temperatures. Fluid breakdown products (due to bombardment and so forth) tend to be electrically conducting. Lubricating qualities are good and the fluid finds application to lubricate mechanisms in vacuum systems. 65cc
