Resolution tests for Gatan 626 cryo-holder: |
Under construction!
The Gatan 626 cryo-holder is wide and has a limited tilt range of ±30° in our JEOL JEM 3200FS. It is very stable and produces high resolution images over the entire tilt range both at room temperature and when cooled to -175 C°.
The images below were recorded using a microscope magnification of X00,000x (Y00,000x at the CCD) and an exposure time of 1 second:
We occasionally record the cooling rate of this holder after it is inserted into the 3200FS at room temperature and then liquid nitrogen is added to the dewar. The following graph shows the timecourse for cooling (with some annotations about drift rates):
