These 15 mL PYREX® tissue grinders are designed to handle both initial grinding and final homogenization in the same sequence of operations. The lower conical section is intended primarily for the initial grinding. To assist in this work the clearance between mortar and pestle can be adjusted at will by raising or lowering the pestle. The upper cylindrical section is for the final homogenization.

These 3 mL PYREX® tissue grinders are designed to handle both initial grinding and final homogenization in the same sequence of operations. The lower conical section is intended primarily for the initial grinding. To assist in this work the clearance between mortar and pestle can be adjusted at will by raising or lowering the pestle. The upper cylindrical section is for the final homogenization.

These 1 mL capacity PYREX® tissue grinders (homogenizers) are recommended for soft tissues found in the liver and brain. They are designed to handle both initial grinding and final homogenization in the same sequence of operations. Mortar is not ground and the pestle contact surface is Polytetrafluorethylene (PTFE), threaded onto a stainless steel shaft. -Caution: If used with a motor-driven device, the attachment must contain…

These motor-driven 3 mL capacity PYREX® tissue grinders (homogenizers) are used in preparing small samples for pathological and biochemical studies. The clearance between the ground tube and pestle is approximately 0.15mm. The parts are ground to a medium grind to insure adequate abrasive qualities, yet deliver a fine homogenous sample. -Caution: If used with a motor-driven device, the attachment must contain some form of fric…

These motor-driven 9 mL capacity PYREX® tissue grinders (homogenizers) are used in preparing small samples for pathological and biochemical studies. The clearance between the ground tube and pestle is approximately 0.15mm. The parts are ground to a medium grind to insure adequate abrasive qualities, yet deliver a fine homogenous sample. -Caution: If used with a motor-driven device, the attachment must contain some form of fric…

These motor-driven 16 mL capacity PYREX® tissue grinders (homogenizers) are used in preparing small samples for pathological and biochemical studies. The clearance between the ground tube and pestle is approximately 0.15mm. The parts are ground to a medium grind to insure adequate abrasive qualities, yet deliver a fine homogenous sample. -Caution: If used with a motor-driven device, the attachment must contain some form of fri…

These motor-driven 50 mL capacity PYREX® tissue grinders (homogenizers) are used in preparing small samples for pathological and biochemical studies. The clearance between the ground tube and pestle is approximately 0.15mm. The parts are ground to a medium grind to insure adequate abrasive qualities, yet deliver a fine homogenous sample. -Caution: If used with a motor-driven device, the attachment must contain some form of fri…

These 45 mL capacity PYREX® Potter-Elvehjem tissue grinders (homogenizers) are used in preparing small samples for pathological and biochemical studies. Homogenization occurs as the sample and buffer are forced through the cylindrical portion of the mortar as the pestle is rotated downward. Mortar is not ground and the pestle contact surface is Polytetrafluorethylene (PTFE), threaded onto a stainless steel shaft. Caution: If u…

These 0.5 mL capacity PYREX® Potter-Elvehjem tissue grinders (homogenizers) are used in preparing small samples for pathological and biochemical studies. Homogenization occurs as the sample and buffer are forced through the cylindrical portion of the mortar as the pestle is rotated downward. Mortar is not ground and the pestle contact surface is Polytetrafluorethylene (PTFE), threaded onto a stainless steel shaft. Caution: If…

These 40 mL capacity PYREX® homogenizers are designed for grinding small samples for pathological and biochemical work. The catch basin bulb has a 55mm outer diameter. Made in accordance with Federal Specification DD-T-363a. 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…

These 40 mL capacity PYREX® homogenizers are designed for use in hand grinding small samples for pathological or biochemical studies. The catch basin bulb has a 50mm outer diameter. The pestle takes a No. 3 rubber stopper. 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 samp…
