Description

The LMB (Laboratory of Molecular Biology-MRC Cambridge) wish to purchase single-tilt holder for cryo transfer and tomography of thin-film frozen-hydrated/vitrified specimens for use in the LMBs existing range of transmission electron microscopes (TEMs) with the following specifications:
• The construction of the standard specimen cup/ holder tip material should be constructed from Beryllium copper material
• Should be able to maintain a temperature below -175 C for 4 hours or more in Cryo Work Station or a TEM.
• Time to reach minimum operating temperature 30 mins or less
• Should be able to tilt to +/- 75 degrees
• Should achieve a resolution at 0 degrees tilt of 0.34nm or higher
• Should enable the frost-free transfer of cryo-specimens to the TEM stage
• Should allow the user to effortlessly secure a grid without the use of additional detachable C-clips or clip-rings that can get lost or damaged.
• Should allow tool-free specimen mounting
• Should accept a 3 mm diameter TEM sample grid
• Should have a low drift-rate of 1.5 nm/minute or better
• The level of liquid nitrogen in the holder dewar should not affect the drift-rate of the holder so as automated data acquisition can be carried out without supervision for at least 4 hours or more.
