A simple to use, easily customized vacuum pumping station for TEM specimen holders. The Turbo Pumping Station evacuates the Model 2550 Cryo Transfer Tomography Holder’s dewar during zeolite regeneration. It can also pump down Thermo Fisher Scientific and JEOL, Ltd. TEM specimen holders and keep the holders under vacuum during storage.

The Model 9030 Turbo Pumping Station is a versatile, configurable device for evacuating the Fischione Instruments’ Model 2550 Cryo Transfer Tomography Holder during zeolite regeneration and for storing transmission electron microscope specimen holders under clean, vacuum conditions.

The Cryo Transfer Tomography Holder’s dewar contains zeolite desiccant, which enhances the dewar’s vacuum level. Zeolite must be regenerated regularly; this requires a high vacuum pumping station. The Turbo Pumping Station reaches an ultimate pressure of < 10^-6 Torr when pumping down the Cryo Transfer Tomography Holder.

The pumping station allows for vacuum pumping of the specimen holder tip while evacuating the dewar vacuum.

Up to four TEM specimen holders can be pumped down and stored in vacuum conditions. The Turbo Pumping Station can simultaneously accommodate both Thermo Fisher Scientific (TFS) and JEOL specimen holders.
Available configurations:

• Basic (TFS): A single dock with a single TFS port; manual port venting
• Single (TFS): A single dock with a single TFS port; automatic port venting; display of vacuum level
• Single (JEOL): A single dock with a single JEOL port; automatic port venting; display of vacuum level
• Quad (TFS and/or JEOL): A quad holder dock; user specifies TFS and JEOL port mix (four TFS ports, four JEOL ports, or two TFS/ two JEOL ports); automatic port venting; display of vacuum level
