Vacutome and Cleaning Mode
The vacutome system provides an active vacuum that aids in chamber cleaning and stretching of sections.
Notes
The user sets the desired value depending upon the intended function (stretching or suction process), section thickness and the
size of the specimen.
The vacuum applied for stretching sections and/or disposing of section waste is only active when within the cutting window.
Outside of the cutting window, the selected vacuum is turned off by means of a valve.
After 10 minutes of inactivity the vacuum will automatically switch off. When activity resumes the vacuum will
automatically switch on. The vacuum takes approximately 2 seconds to reach full efficiency.
The Vacutome system is provided with two different-length nozzles. The longer nozzle is optimized for use in specimen
stretching and aids in keeping the cryo chamber clean. The shorter nozzle is optimized for use with the anti-roll plate in
appropriately stretching specimens.
