Fully Motorised 6 AXES Liquid Helium Manipulator from Prevac

Prevac’s 6 AXES Liquid Helium Manipulator is a versatile, open cycle system suitable for a range of X, Y and Z linear motions and R1, R2 and R3 rotations. This high precision, high rigidity manipulator has a modular construction, which means that the specification can be modified or upgraded by adding or replacing well-defined modules.

The 6 Axes Manipulators are used for manipulating scientific tools and sample holders with respect to a sample’s position.
