Leica LN22

Nitrogen freezing device

Leica LN22 nitrogen freezing attachment with Leica RM2265 rotary microtome

Overview

The Leica LN22 liquid nitrogen freezing attachment was designed specifically for use with the Leica RM2265 rotary microtome. Sections of uncompromising quality can be obtained from even the most challenging specimens in the fields of industry and materials research - at section thickness settings between 0.25 and 100 µm and working temperatures as low as -150 °C.

With the Leica RM2265, changing from ambient temperature to low-temperature sectioning and vice versa can be realized quickly and easily.
