In situ MX Crystallography

The Plate Manipulator is a motorized crystal plate holder for standard screening plates (96-well plates) that is dedicated to in situ MX crystallography.

Its integrated motorized axis is combined with the translational and rotational movements (alignment table & Ω axis): in this way, the crystallization plate can evolve in 3 dimensions, giving access to the 96 wells.

The Plate Manipulator has an excellent flexibility: it is easy to mount and dismount on Arinax diffractometers and it can be easily exchanged with other Arinax goniometer heads, such as the Mini-Kappa MK3.

5 minutes switchable equipment

In order to offer the best flexibility to users, the Plate manipulator, the Mini-kappa MK3 and the SmartMagnet are designed to be easily mounted and dismounted according to user need: the switch from one to another takes about 5 minutes and only one person is required to do the switch.
