Radnoti tissue grinders are constructed out of borosilicate glass and are designed for dependable performance, efficiency and durability. The Radnoti tissue grinder line covers applications from microliter samples to large tissue samples, from delicate preparations to disruption of tough connective tissue. The capped tissue grinders reduce problems caused by tipping and spilling of homogenates into ice baths and also limit aerosol contamination of the environment by the samples. The latter property is appreciated when dealing with pathogenic samples or potentially hazardous protease inhibitors. For applications that do not require the grinder to be capped or demand the optimal yield seen with our "Preci-Grind " grinders, Radnoti offers the Econo-Grind line of tissue grinders. A precision ground ball pestle provides rapid grinding action and fast tissue dispersion.
