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 […]
