25mm Bore Differentially Pumped Rotary Feedthrough (DPRF)

The VACGEN rotating platform provides the means of translating rotation through a vessel wall without losing vacuum integrity, enabling probes or assemblies to be inserted without effect on the chamber pressure. To maintain the rotary seal, a vacuum port is mounted to the side of the assembly allowing connection to an appropriate pump.

25mm clearbore with coarse and fine control available in addition to motorised options.
