Abstract
A holder provided with an oscillatory movable ultramicrotome cutter which is arranged on a cutter holder and oscillatory movable by means of a piezo-electric element. The cutter is supported by the piezo-electric element. The holder can be easily produced with high dimensional accuracy. It makes it possible to oscillate the cutter blade at a high frequency.
Claims13
A holding device for an ultramicrotome, the device comprising:
- a cutter having a cutting edge,
- a stationary cutter holder, and
- a piezoelectric element, the piezoelectric element having a first supporting surface and a second supporting surface, the first supporting surface being fastened on the cutter holder and the cutter being fastened on the second supporting surface, the piezoelectric element being adapted to oscillate said cutter relative to said cutter holder,
- wherein the cutter is supported on the cutter holder exclusively by the piezoelectric element and is otherwise freely suspended on said cutter holder.
