Hollow Shaft Sample Transporter DN40CF

Product code: RMHS40-XXXX-YYYY

Based on the RM40 sample transporter, it's tubular shaft however being considerably lighter than a solid one, it also helps avoid excessive thermal conductance. It is commonly used as a manipulator for sample insertion into cryogenic SPM's but of course it's lighter hollow shaft offers advantages for other applications as well.

Whenever mounted vertically, for safety reasons it's strongly recommended to use it in combination with an IVBR in-vacuum brake, to prevent the inner shaft from suddenly dropping in case the magnetic coupling should slip from the user's grip. An optional TSRMBD belt drive can facilitate handling once the height of the system and/or length of the sample transporter make it hard to reach and manipulate.
