[3dem] Gatan 655/626 Maintenance

[Guilliams,Bradley]

Hi Everyone,

We have a Gatan 655 Turbo Pumping Station and 626 Cryo Transfer Holder that have sat unused for a number of years. The pumping station has been 'on' consistently pulling vacuum on the 626 holder, but the gauge is not working. I was hoping the community had a lead on replacement kits for the Diaphragm pump and the MDP (originally Kit #10546 and #05577, respectively) as no maintenance has been done on the pumping station for at least 3-4 years. The instruction manual that I have for the 655 has instructions to 'service the Cold Cathode Gauge Tube' which essentially entails blowing it out with compressed air-how often does this actually fix the gauge when it the needle is reading/stuck to the far-right of the gauge?

Any advice here or leads on replacement parts would be much appreciated.

Cheers,
Bradley
