Figure 3
Picture showing the VMXm sample holder and sample cartridge. (a) An empty copper sample holder is shown, the empty opening holds a cryoEM grid, held in place by a c-clip. The opening to this is angled to allow diffracted X-rays to reach the detector and for as much rotation as possible for data collection. The base of the holder is a large copper mass to maintain the low temperature of the sample. (b) The open sample cartridge constructed from aluminium. This shows the five positions for holding each sample holder. (c) The closed sample cartridge. The cartridge has a lid to maintain low sample temperatures and reduce water ice formation on the samples while the cartridge is being transferred to the beamline. On the base of the cartridge two cutouts can be seen where the claw mechanism fits for transferring the cartridge from liquid nitro­gen into the airlock.
