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).
For tissue processing and resin embedding, automation is the safest and most reproducible route, minimize cross contaminations.
After Ultramicrotomy, most sections require contrasting with lead and Uranyl salts. QG3100, capable of contrasting up to 40 grids in one run.
