Fast Pump Down Dock with LN2 Dewar – DN40CF
Couldn't load pickup availability
The Fast Pump Down Dock is designed for rapid sample transfer between portable UHV suitcases and stationary ultra-high vacuum (UHV) systems.
By combining turbomolecular pumping with integrated liquid nitrogen (LN2) cooling, the docking chamber enables rapid pump-down to approximately 1 × 10⁻⁸ mbar in just 30 minutes, significantly reducing downtime between sample transfers.
The integrated cryogenic heat exchanger provides efficient cooling to approximately 80 K, while the vacuum-insulated LN2 dewar minimises thermal losses.
The compact DN40CF interface allows integration into compatible UHV systems and sample transfer configurations.

Applications
The Fast Pump Down Dock is particularly suitable for UHV sample transfer systems requiring short pump-down cycles and minimal exposure to atmospheric conditions.
Typical applications include surface science, synchrotron research, thin-film characterisation and vacuum-based sample preparation.
Scope of Delivery
The docking assembly includes the DN40CF gate valve, integrated LN2 dewar and cryogenic heat exchanger. A thermal insulation sleeve and dewar lid are also included.
A turbomolecular pump is not included.
