REMINDER ! PLEASE RESERVE YOUR NMR TIME FOR GG500 AND 300 INSTRUMENTS !
Dear Users While we are very happy to see that you are all getting comfortable with the truely ‘walk-on’ nature of running NMR with our new NEO500 system, unfortunately, this process cannot yet be replicated on the other instruments. Until we get a fully automated setup with multiple sample handling on the other instruments, YOU […]

UPDATE ON NEO500 – SYSTEM WILL GET TO MAINTENANCE MODE IMMEDIATELY
Hello All The hardware parts reached earlier than exepcted, and the system is not shimming at all with the current configuration. It makes sense, therefore, to swap the hardware without any further delay and test it. As an upside, if everything goes well, the instrument will be released much earlier than expected. Please wait for […]

NEO500 : IMPORTANT CLARIFICATION ABOUT TUBE LENGTHS

UPDATE ON AV300 : SYSTEM HAS UPGRADED VT CONTROL NOW !
Dear Users Thanks to a low temperature chiller that we repurposed from the recently decommissioned AV500 console, the AV300 system now has much better temperature stability and also the capability to lower your sample temperature close to 0 deg. C, if you wish to. Temperature stability is quite important, when it comes to Lock and […]
