The GT31 is an improved version of the standard dual-shaft stirring system that has been a favorite with chemists and lab technicians everywhere. It has a totally enclosed, 1/40 hp, permanent-magnet motor with two output shafts for maximum speeds of 4000 and 333 rpm. The armature shaft provides high speeds for mixing light materials, while the geared shaft generates 3.6 lb/in. of torque at slower speeds for stirring more viscous mixtures. Continuously variable speed control.

The GT31 stirring system is furnished complete with motor and mounting bracket, controller, and the following accessories: 3-jaw, keyless chuck, paddle, propeller, right angle clamp. Lab stand not included.

The GT24 offers the user a stirrer with more power than the GT31 and a selection of speed ranges up to 2500 rpm. This model combines today's permanent-magnet motor technology with solid-state electronics. It features totally enclosed, 1/17 hp, cool, and quiet-running motors with direct-drive and geared options, with continuously variable speed control. Models are available with speeds up to 2500 rpm and torques up to 12 lb/in.

The stirring system is furnished complete with paddle, propeller, 3-jaw, keyless chuck, heavy-duty 90-degree clamp.

This powerful stirrer has a totally enclosed, 1/8 hp, cool, quiet-running, permanent-magnet motor in direct- and gear-drive models with torques from 3.1 lb.in. to 96 lb.in It provides a stirrer with more power and a selection of speed ranges up to 2500 rpm with a continuously variable speed control.

The stirring system is furnished complete with propeller, 3-jaw, keyless chuck, heavy- duty 90-degree clamp. Lab stand is sold separately.

Combination laboratory stirrer and stir-tester. The HST series are supplied with a digital control that makes stirring and viscosity testing more precise. The HST10 is available in direct-drive or geared models with a totally enclosed, 1/17 hp, permanent-magnet DC motor. The direct-drive model provides 20 to 2500 rpm and 1.5 lb.-in torque. The geared models provide 6:1 and 12:1 ratios for max. speeds/torques of 417 rpm/5.4 lb.in. and 208 rpm/12.0 lb.in., respectively.

The system is furnished complete with drive motor, mounting bracket, controller, 3-jaw keyless chuck, paddle, propeller, heavy-duty 90-degree clamp. Lab stand is sold separately.

Combination laboratory stirrer and stir-tester. The HST20 lets you maintain stirring speed with a 1/8 hp, totally enclosed, permanent-magnet DC motor. The direct-drive model provides speeds up to 2500 rpm and 3.6 lb.in of torque. The geared model gives 2 to 265 rpm and torque of 21 lb.in. Other models provide torques up to 96 lb.in.

The system is furnished complete with drive motor, mounting bracket, controller, 3-jaw keyless chuck, propeller, heavy-duty 90-degree clamp. Lab stand not included.
