These PYREX® homogenizers are designed for use in hand grinding small samples for pathological or biochemical studies. The mortar tubes and pestles are ground to be interchangeable. Clearance between the two parts is approximately 0.15mm. The medium grind provides the required abrasive action to deliver well homogenized samples. Made in accordance with Federal Specification NNN-T-360B. It may be used manually but is adaptable for use with a slow speed stirrer by means of a rubber stopper and a connecting rod.
Caution: If used with a motor-driven device, the attachment must contain some form of friction release clutch to prevent damage to the apparatus from pieces of connective tissue or muscle. The user should wear a protective glove of sufficient thickness to prevent injury in the event of failure of the glass components.
