AV700 – UPDATE : PNEUMATICS BOARD MALFUNCTION
Probably due to a voltage surge this weekend past, the pneumatics control board on 700 appears compromised. No VT regulation or sample transport is possible due to this and we are energetically trying to resolve the issue. Please look for further updates in this space. The machine is unusable until then.

DRX499 : UPDATE – OPERATIONAL WITH LIMITED FUNCTIONALITY
The spectrometer with the TXO probe is operational fully with 1H and 13C channels. The 19F is not yet ready for prime use as I write this and I will post an update once that issue is resolved as well. The instrument is open for regular use, with the above caveat.
