Zero Z without the hassle
You may be asking yourself, "how is the Compresstome different from a vibratome?"  You can read about a discussion thread on ResearchGate on selecting the best tissue sectioning tool for you.
The Compresstome is also the best machine to cut adult and senior brain slices.  The paper and the associated protocal can be found in  Brain Slice Methods .

The VF-700-0Z is designed specifically for sectioning fixed tissues.  With a wider diameter of 21 mm, it can accomodate both rat as well as mice brains.  With our patented compression technology, this fully automated slicer excels at sectioning slices used for
The Auto Zero Z technology eliminates any need for making mistakes on your own Z axis tuning.  It will allow you to section thin and completely smooth tissues for your immunohisochemistry work.  
The Compresstome™ is also easy to use, our online training videos will allow everyone in your lab to produce excellent slices.

  1. "For the past several months, I have been using the Precisionary Instruments Inc VF-200 to cut 300 um prefrontal cortical slices for electrophysiological recordings. As a result, I have been consistently cutting exceptional quality brain slices and have succeeded in obtaining stable whole-cell patch recordings from numerous neurons. Because I am using transgenic mice that have fluorescent reporters, it is of great importance to achieve maximal cell viability and minimal cell death. When I use the VF-200, I have significantly greater number of surface neurons than those slices cut from a regular Vibratome™. In addition the slice surface is much more even, which allows for better imaging. I am thoroughly impressed with the VF-200 and would not hesitate recommending this quality product to fellow electrophysiologists."

  2. We obtained a VF-300 Compresstome™ about 5 months ago to use alongside a microtome that we had exclusively used for at least 5 years prior. The VF-300 is more consistent in generating uniform slices and leaves the structure of the tissue/cells more intact than the method we had been using. We have been able to extend the amount of time over which we can cut lung slices, and allows preservation of the architecture of the slice and greater viability of the tissue.

  3. With the Compresstome™ I was able to prepare high quality slices with excellent preservation near the slice surface. The main advantages of this machine are the rapid speed of slicing and the manual stabilization afforded by the agarose embedding. I am able to prepare uniform slices in both the coronal and horizontal planes, and I routinely complete transcardial perfusion, brain removal, and slicing all within less than 10 minutes, which is half the time needed with the Vibratome model. By limiting the time required for slicing the brain tissue is able to recover more easily without significant anoxia, and my slices stay viable for up to 8 hours. I have successfully been able to do targeted whole-cell recordings from fluorescently labeled neurons in slices prepared from >1 year old mice, which is not generally possible with conventional slicers and methods.

  4. We found the Compresstome produces a less apparent damage to the cells of the airways and arterioles as well as to the delicate alveolar parenchyma. Using the Compresstome we are able to obtain more reproducible and successful experiments.

  5. We spent six months trying to cut our tissue (avian olfactory) with a Vibratome..... but without success. It took just 10 minutes with the Compresstome, and the sections are beautiful. It's the best investment my lab has made.

  6. At first, I was skeptical about the VF-200, 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.
