The Agilent Varian HS-2 has been designed to fill a special need in applications where high pumping speeds are required and space limitations demand a compact pump. This unit, smallest of the HS Series pumps, is well suited for laboratory and research use. The HS2 pump is a rugged, general-purpose unit with an operating range of 2 x 10-3 to / min, without the use of any anti-cooled cold cap with only a slight reduction in pumping speed. Inlet Flange 2 inch ASA, 6 inch OD.
