ALERT ! AV500 – POSSIBLE PROBE CHANGE – VT DEWAR DAMAGED

The VT dewar inside the probe has been compromised and so you CANNOT run Variable Temperature experiments currently. ONLY nominal room temperature experiments are allowed at this point. We will most probably place a different probehead in place of the current HCP-Z Gradient probehead while the current probehead is serviced.  We will try to do […]

UPDATE ! AV700 : SYSTEM IS RELEASED FOR USE – PLEASE READ

The system is ready for normal use.  Nevertheless, the VT system test is still being conducted in parallel in such a way that the users’ runs are not affected.  As before, the LN2 tank you see is the source of the N2 gas, which is used as part of the troubleshoot process. The supply from […]
