This economy microtome is for introductory biology and histology work.  We also sell this with a wooden box for storage.  Suitable for slicing micro thin sections from 0.01mm (10 microns) to 10mm.  The microtome consists of a fine threaded piston which screws into a stage for sectioning.  The advancing of the piston is uncalibrated. The knurled head at the bottom of the instrument moves the piston up or down the central tube when rotated.  The specimen is fixed on the flat top of the piston and sections are cut by drawing a razor over the upper flat surface of the instrument.  Approximately 55mm (height) x 20mm (width) 50mm (diameter of base).
