BRIGHTON, England, November 20, 2014 /PRNewswire/ --
Using an innovative telescopic mechanism, the Radial Telescopic Transfer Arm (RTTA) represents a step-change advance in the precise radial transfer of samples between multiple preparation and analysis chambers. The RTTA's unique telescopic mechanism extends over twice as far as conventional designs (extending to 760mm) and provides exceptional stability with <1mm deflection at full extension with a 1Kg load. The RTTA is comparable in cost to conventional transfer arms with the additional benefit of allowing the use of a much smaller distribution chamber. This saves space and results in reduced cost for the chamber and associated vacuum pumps.

Users of the RTTA include research facilities, system manufacturers and universities. One such user Alexander Kozen, ANSLab, University of Maryland said: "Our sample transfer time has improved by approximately a factor of 10. This RTTA is well designed and constructed; transfer is smooth, accurate, and fast. The RTTA is truly an excellent piece of engineering."
The RTTA provides true UHV rotation with no oil, slip rings, bellows or differential pumping and provides extremely precise radial motion. This radial motion is used to align the transfer arm with the desired chamber port achieving angular reproducibility of <0.2mRad. An innovative telescopic mechanism then provides arm extension of 760mm (twice the reach of conventional systems) to transport the sample in and out of the desired satellite chamber. The precision slide mechanism achieves linear reproducibility of <0.2mm. There is also a sample arm lift/lower option for 'gravity based' sample hand-off.
UVD Design will be showcasing the RTTA on the Kurt J Lesker stand (booth 400) at the MRS Fall Meeting that will be held in the US from November 30th to December 5th. More information on the RTTA can be requested directly from UHV Design Ltd.
