A magnet free stirrer with extremely precise speed control
The universal USB stirrer ST1.S enables solution stirring during a measurement with screen printed electrodes and classical electrodes. The construction of the stirrer assures the optimal mass transport with minimum hydrodynamic noise. The supply voltage (3 V) and current the max current (150 mA) enable the user to use it as an USB device. The speed range is 100 – 1000 rpm. If the cells TC4, TC5 or TC6 by BVT are used, the device can be easily plugged into the central opening. The body is made of PEEK and thus resistant to common solutions. The speed controller allows a very precise controll and the the brushless motor a robust and reliable rotation. With this stirrer a controlled diffusion layer can be achieved and a rotating disc electrode like measurement can be performed.
