LN-Ultra

High-stability cryo chamber for sectioning and planing

Capable of holding temperatures down to -180°C, the stable environment of the LNUltra is perfect for sectioning and planing a variety of samples. These include rubber and soft polymers, as well as biological cells and tissues, for example for immunolablling using the Tokuyasu technique or CEMOVIS.

The LNUltra is a liquid nitrogen-cooled cryo chamber attachment for the Powertome ultramicrotomes. The 12 litre dewar can provide a stable sectioning environment for around seven hours due to the low LN2-consumption.

In combination with the Powertome 3D, with its 1mm advance, many sections can be trimmed and cut without resetting, negating the need for realigning the sample and block.
