Sample Transporter DN40CF

Product code: GMD40-XXXX-YYYY

The GMD40 is a simple all metal sealed, linear-rotary feedthrough for ultra high vacuum applications. It's main purpose is to transport samples 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. Sapphire hybride, dry lube coated ball bearings in combination with a specially designed slide bearing guarantee for smooth operation even after numerous bakeout cycles.
