The Flex robotics family
Designed to handle sample holders used in Macromolecular X-ray crystallography, the Flex robotics family is built around a 6 axis industrial robot. The family currently includes 3 members equipped with different storage Dewars. They are all provided with a tool changer and various handling tools.
FlexED8 (picture), a sample changer compatible with SPINE, NewPin and miniSpine sample holders that can hold up to 252 sample holders in a small footprint open Dewar with built in ice filtering system. Different cryo-grippers are used to safely transfer the sample holders to a goniometer. The sample exchange time can be as low as 4 seconds when the Twin SPINE cryo-gripper is used. FlexED8 was developed in the context of the NewPin project and tested on the EMBL/ESRF/INDIA BM14 CRG beamline.
FlexHCD, a sample changer compatible with SPINE sample holders. It includes a modified High Capacity Dewar initially developed within the ESRF MX group. It can hold up to 384 samples in uni-pucks or 240 samples with vials in SC3 pucks, or a mix of the two. The sample holders in uni-pucks are transferred using a single or a Twin cryo-gripper and with the IRELEC-Alcen flipping gripper when stored with vials in SC3 pucks. FlexHCD is installed at the ESRF ID30B beamline and being duplicated to equip four other ESRF MX beamlines.
FlexED3, a cryo-storage unit associated to a CrystalDirect™ (see below) harvester to automatically store crystals harvested with SPINE sample holders in SC3 pucks. FlexED3 is currently in operation at the Grenoble HTX lab.
The CrystalDirect harvesting station
Operated by the HTX lab since 2017, it allows to automatically harvest, vitrify and mount on SPINE sample holders crystals of any size, as well as micro-crystals harvested in batches.With a storage capacity of several hundred samples in SC3 pucks or in uni-pucks and a turnover time of 1'30", it is extensively used in fragment screening applications.
