Dual Shaft Single Rotary Sample Transporter

Product code: RMD40-XXXX-YYYY

The RMD40 is an extra sturdy all metal sealed, vacuum-side-all-metal transfer rod with independent rotation of the inner shaft. It's main purpose is to transport samples between UHV-chambers. Its square shaped tubular shaft provides higher stability compared to solid shaft sample transporters and is therefore the ideal choice for longer stroke models >750mm and/or whenever heavier loads are transferred.

In addition, the independent rotary motion allows for operating a pincer or a rotatable sample carrier platform. A set of rare earth magnets on the air- and vacuumside provides the necessary force to ensure a rigid coupling from the handle to the shaft. The square shaft and inner shaft are guided by Dicronite (WS2) dry lube coated sapphire hybride ball bearings.

Standard shaft orientation is as indicated in the image on the left. Shaft orientation may be of importance in when a PGRMS pincer is installed.

Depending on the chamber flange bolt hole orientation, the pincer jaws will open in a horizontal or a vertical plane. For a 30° rotated shaft orientation, please specify the (H) option.





  • Standard strokes: 0500 / 0750 / 1000mm
  • Standard retracted length: 0050mm
  • Customized stroke: Specify XXXX min. 50mm / max. 1000mm
  • Customized retracted length: Specify YYYY min. 45mm / max. 200mm

Standard example: RMD40-0500-0045 = Single Shaft Sample Transporter DN40CF, 500mm linear travel, 45mm retracted length.

Customized Example: RMD40-0650-0100 = Single Shaft Sample Transporter DN40CF, 650mm linear travel, 100mm retracted length .
