Transax UHV Sample Manipulator
The Transax is a stable and versatile, fully UHV compatible sample manipulator. The modular design can offer long Z travel up to 600mm and when combined with a rotary drive and sample handling equipment offers a rigid sample interface with good stability. Situated on a 152mm OD CF base flange, the design eliminates bi-metal deformation even after repeated bakeouts to 230°C. An optional support tube with secondary support bearing in the XY table improves sample stability by more than 5x than a cantilevered support tube. Optional heating and cooling modules can be added to the sample holder to allow for variations in temperature from -165°C to +1200°C.

Transax Accessories
Additional modules include rotary drives, sample holders, differentially pumped rotary feedthroughs, sample heating, liquid nitrogen cooling, stepper motor controllers and support stands:
Rotary Drives
Feedthrough chamber required for UHV Rotary Drives modules. These play a pivotal role in analytical instruments, precisely positioning samples for accurate readings and analyses.
Sample Holders
Sample holders are the interface between the sample and the movements of the manipulator. The Transax is compatible with all sample handling options.
Sample Heating
Resistive and Electron Beam Heater Modules can be fitted to the sample holders to provide sample heating up to 1200°C. Explore PBN, HST and EBH heaters.
Liquid Nitrogen Cooling
Liquid Nitrogen Cooling can be configured to the manipulator providing cooling of the sample down to temperatures of -165°C.
Motorisation
Stepper motor controllers are available to power and control all motorised instrumentation for X,Y, Z and R1, R2 and R3 axes. These can be configured up to 99 axes in open/closed loop.
DPRFs & Rotary Platforms
Differentially Pumped Rotary Feedthroughs (DPRF) and Rotary Platforms can be fitted to the manipulator to provide additional means of rotation into the chamber.
Support Stands
Larger manipulators require support stands to stabilise the manipulator when mounted in a horizontal orientation, we provide 3 standard variations.
Analysis Chamber
Our vast portfolio of bespoke chamber and system projects, gives us a wealth of knowledge and experience for one-off chamber builds.
