- For correlative cryo-light (inverted) and cryo-electron microscopy (CLEM)
- -190°C - 120°C with resistive heating and liquid nitrogen cooling option
- Grid holder allows nine EM grids, 3 mm round, to be imaged via bright field and fluorescence light microscopy to improve productivity
- Grid holder designed for vitreous operation and transfer far below the amorphous ice phase transition temperature
Description
Instec's CLM77Ki is a specialized stage designed for use on any uinverted 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 CLM77Ki 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 CLM77Ki chamber.
