- Grid holder designed for vitreous operation and transfer far below the amorphous ice phase transition temperature
Description
Instec's CLM77K is a specialized stage designed for use on any upright microscope for correlative cryo-light and cryo-electron microscopy (CLEM). The specially designed grid holder allows up to nine 3 mm EM grids to be images via bright field and flourescence light microscopy for determination of regions and/or cellular events of interest for later observation in the electron microscope. The grid holder is designed to keep the grids vitreous - well below the amorphous ice phase transition temperature - during tranfer of grids into the grid holder and then into the CLM77K stage. To eliminate frost build-up on samples, the chamber can be gas purged and the grid holder has an integrated slide cover that is closed during transfer from liquid nitrogen into the CLM77K chamber.
