• Features

♦ Equipped with a unique two-stage rotation control: when the load is within the maximum torque, the set rotation speed is maintained via speed feedback control; if the load exceeds the limit, the speed is reduced to continue stirring.

♦ The product has a DC brushless motor and is a powerful, compact stirrer with an accurate rotation display using a pulse count system. Because it is brushless, there is no sparking, and there is no need to worry about wearing out or replacing brushes. Includes multiple safety features: a thermal protector to prevent motor burnout, current limiting circuit, and independent power switch.

• Chuck cover

A protective chuck cover prevents hair and foreign objects from being caught in the rotating drill chuck. (PAT.)

• Free clamp mechanism

The free clamp mechanism with a wide adjustable range allows the unit angle to be easily set with a single knob. This makes it easy to align the centers of the stirring seal, stirring rod, and flask. The large-diameter ball joint in the free clamp ensures stable holding.

• Air purge port

External air can be supplied into the stirrer housing to prevent the intrusion of solvents or corrosive gases.

• Two (2) types of chuck parts

The standard type is a drill chuck (left) that can be securely fixed with a chuck handle.
The reversible type is a collet chuck (right) that can be easily tightened by hand.

• Reversible function

The reversible models allow users to switch between forward and reverse rotation via a selector switch for efficient mixing. Available on ZZ-xx1x series only.

The automatic reverse function model can be set to 0, 5, 10, 20, 30, 45, or 60 seconds. ZZ-xx2x series only.

• External input/output terminals

Signal control is compatible with reaction systems and other automated applications. Rotation speed can be remotely controlled via 0–5VDC signal input from a computer or process controller. Changes in rotation speed and load torque are output (0 to 5VDC) separately, making data processing easy.

♦ External input/output terminals are only available on the ZZ-xx2x series.

• Speed ​​feedback control maintains rotation

① Even if there is a load fluctuation during stirring, the speed feedback control maintains the set rotation speed as long as the load remains within the permissible range.

② If the load exceeds the permissible range, the unit continues to operate by reducing the rotation speed.

♦ Torque display is available only on the ZZ-xx2x series.
