Yes, this does sound like a pressure issue. There is a screw in the back of the unit that can be adjusted. I have had similar problems with two different units. Once adjusted properly you should have no problems.

Subject: [3dem] Cryoplunge 3 question


    We are currently demo'ing a Gatan Cryoplunge 3 (CP3) freezing robot.  From time to time (and randomly as far as we can tell), there is a significant delay between the time the start button is pushed and when the blotters actually close.  Since the countdown for blotting time starts when the button is pushed, the delay causes the actual blot time for that particular grid to be too short.  Does anyone else who has a CP3 see this issue, and if so, is there anything that can be done about it?  Thanks in advance.

    politics is more difficult than physics.
