Cryo Ultramicrotomy LN Ultra Advanced, Stable Cryo Sectioning System For Ultramicrotomy Sectioning of both biological and industrial materials can be achieved with the LNUltra, a liquid nitrogen-cooled cryochamber attachment for the PowerTome series of ultramicrotome. Mounted onto the PowerTome, the LN Ultra provides optimal thermal stability necessary for producing cryosections. Capable of holding temperatures from +40°C to -185°C, the stable environment of the LNUltra is perfect for sectioning and planing a variety of samples. These may include rubber and soft polymers, or biological cells and tissues; used for example, for immunolabelling using the Tokuyasu technique or CEMOVIS (Cryo Electron Microscopy of Vitreous Ice Sections). Liquid Nitrogen consumption is very low, allowing for a size efficient 12 liter Dewar. This can provide a stable sectioning environment for up to nine hours, while saving your laboratory LN2 costs over less efficient systems. May not be compatible with older PowerTome models; if an LN Ultra is being purchased to be used with a previously purchased PowerTome, we will require the serial number of the PowerTome in order to determine compatibility. Users with a noncompatible PowerTome will require the additional purchase of the current model of the PowerTome controller (P/N 75670) in order to operate the LN Ultra with their PowerTome.
