产品详情Agilent Varian AX-65 Diffusion Pump, KF50 Inlet, 250 Watt Heater with Baffle, Designed For Santovac 5 Oil, 65 l/s of Air Pumping Speed
Air Cooled, Operates On 1-Phase 90 VAC, Agilent Varian Part Number L9670315
These Agilent Varian model AX-65 high vacuum diffusion pumps are air cooled and the primary industrial standard for compact high vacuum pumping. The Agilent Varian AX-65 diffusion pumps have a high pumping speed for all gases and the lowest cost per unit pumping speed when compared with other types of pumps used in the same vacuum range. The AX-65 pumps feature glass fill and drain assemblies for easy maintenance of diffusion pump fluid and continuous monitoring. These AX-65 models include a finned boiler which increases the surface area and prolongs fluid life. The full fractionating design allows vaporized fluid to be fractionated in the boiler and jet assembly. Contamination and decomposition products are pumped away and only the purest vapor reaches the top jet, assuring highest speed and lowest backstreaming.
This Agilent Varian AX-65 Diffusion Pump Includes:
Air Cooled Diffusion Pump With Fan, PN L9670315
Inlet KF50, Outlet KF16
Internal Baffle (prevents backstreaming)
90 VAC @ 250 Watt Heater (Designed To Be Used With Santovac 5 Oil)
Diffusion pumps use a high-speed jet of vapor to direct gas molecules in the pump throat down into the bottom of the pump and out the outlet. The oil diffusion pump is operated with an oil that has low vapor pressure (Santovac 5 or IVP 704 depending on the heater harness). Its purpose is to achieve higher vacuum (lower pressure) than possible by use of positive displacement pumps alone. The Agilent Varian AX-65 can pump down to pressures of 5x10-8 Torr. Diffusion pumps cannot discharge directly into the atmosphere, so a mechanical forepump, roughing pump is typically used to maintain an outlet pressure around 1 mTorr.
