Basic Information
Leica 3050 S, manufactured by Leica, Germany
Instrument Functions
Leica 3050 S freezing microtome is used for freeze tissue sections.
Instrument Components
- Refrigeration box: Refrigeration, insulation and slicing operation
- Refrigeration compressor: Refrigeration
- Sampling system: Sample injection before slicing the frozen sample
- Tool rest: Installing and fixing the blade
- Tool rest base: Fixing the tool rest
- Cutting tools: Slicing the frozen sample
Basic Working Principle of System
The refrigeration compressor accurately controls the low temperature in the freezer. The sample head of the slicer moves forward and backward by the precision sampling systems. And it wings vertically downward by the rotation of the hand wheel and approaches the blade according to the sampling distance set by the user, so as to cut off the thin slice.
Main Technical Parameters
- Anti-splash design.
- Dual compressors, independent compressors to refrigerate the sample head, so as to the more accurate temperature control.
