Leica EM UC7 ultramicrotome equipped with the FC7 cryo chamber 

 

The Leica EM UC7 ultramicrotome equipped with the FC7 cryo chamber attachment is capable for preparation of high quality semi- and ultra-thin sections of biological and industrial samples. This includes frozen hydrated sectioning of vitrified specimens, cryoprotected biological  samples and soft materials like rubbers and polymers. 

 

> Wide temperature range for sectioning, starting at room temperature and down to -180 C.

> The FC7 cryo chamber is equipped with a micromanipulator for easy sections transfer to the TEM grid.

> Precise thickness control of sections from a few nanometers to up to several micrometers

> Equipped with a built in antivibration system
