Sample Transporter DN40CF

Product code: RM40-XXXX-YYYY

The RM40 is a simple, all metal sealed, linear-rotary feedthrough for ultra high vacuum applications. It's main purpose is to transport samples in between UHV-chambers. A set of rare earth magnets on the air- and vacuum side provides the necessary force to ensure a rigid coupling from the handle to the inner shaft. Slide bearings guarantee for smooth operation even after numerous bakeout cycles.

Order code customized version:


  • XXXX: linear travel in millimeters (max. 1250mm)
  • YYYY: retracted length, flange face to end of shaft in millimeters (10mm - 200mm)
