I would check that there is sufficient N2 pressure. The mechanism is pneumatic. At low pressure it can get stuck or not move all the way. You could try to increase the gas pressure at your N2 cylinder regulator and check for any leaks at the fittings. </div>

<div class="PlainText">Hi,<br>
<br>
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.<br>
