We pushed technology to the limit to offer the possibility to dissect really thin slices. State-of-the-art manufacturing ensures that Alto 0.5mm* brain blocks have the narrowest channels separated by the finest walls on the market to enable you to cut up your sample into really fine slices.

Made of high quality stainless steel, harder than zinc, aluminum, or acrylic, Alto matrices will last longer withstanding repeated cleaning and autoclave sterilizing cycles. They can be cooled and used in experiments involving frozen tissue. The stainless steel material has no plating so its surface will not get ruined/chipped by the heat tension and it will not get chipped as a result of mechanical impact.

The strong stainless steel material drives the cutting blade firmly providing the accuracy needed for your research.

Alto 0.5mm* matrices may be used to produce sections for pharmacokinetic studies using the brain slice uptake method, for the dissection of discrete regions of a rodent brain for the biochemical analysis of various substances, and for the accurate blocking of organs for microtome sectioning.
