Compresstome™ microtome
Compresstome™ is a new family of microtomes developed from our company's patented technique. The unique features of this technique are specimen embedding and tissue compression just before tissue slice is made, allowing for much thinner slices to be cut with minimal effort and better image quality.
Biological specimen, live or fixed, is glued on the plunger of a specimen tube and embedded with low gel point agarose within the tube. The front end of the specimen tube is smaller to form a compression lip towards the agarose-specimen block. When agarose-specimen block is pushed forword by the plunger, it is compressed by the compression lip. The extruding specimen is sectioned by a sharp blade at the front end of the specimen tube. Much better slice quality is achieved when specimen is compressed. The compresstome™ family of microtmes overcome the specimen move/wobble problems and produce high quality slices with excellent viability, consistent slice thickness, flat, and clean surfaces with sharp image.
The compresstome™ family includes four members; the VF-200, VF-300 and VF-600. The compresstome™ VF-200 is designed for electrophysiology experiments. It is a semi-automatic microtome with manual slice thickness adjustment through a micrometer. It is economical and very effective for cutting small quantity of slices. The compresstome™ VF-300 and VF-600 are fully automatic microtomes. They are suitable for preparing large quantity of slices. Within the three, the compresstome™ VF-300 is for live tissue sectioning. The VF-600 is the model for fixed tissue sectioning.

Testimonial on the Compresstome™ VF-200
"I was lucky to be the first one to try the VF200 made by Precisionary Instruments Inc. At first, I was skeptical, but the results were astonishing. I have been using a Vibroslice™ (Campden Instruments, Leicester , UK ) for over 13 years, and I would never get so many living cells in one field as with the VF-200. This is also true and especially impressive for tissue of older animals. The oldest rats we used were 31 days of age. The cell quality was very good and the field was very clean. The VF-200 has greatly improved our productivity. Many thanks to Precisionary Instruments Inc. for creating such a wonderful instrument, and for their significant contribution to the neuro-science field."
