Magnetic stirrer, operated by water/air pressure

Magnetic stirrer, operated by water/air pressure
PP-ABS construction. This unique stirrer is operated either by water pressure between 1 kg/cm² and 2.5 kg/cm² (15 psi to 40 psi) or by air pressure. No electrical supply is needed, thus eliminating heat, electric shock and explosion hazards. Corrosion-proof, all-plastic construction. Can be used on the bench or clamped to a stand with a 12 mm (½'') diameter rod using the integral bosshead.
