1、Place the instrument on a relatively smooth surface, preferably on a glass countertop. Gently press down on the instrument to make the rubber feet on the bottom of the instrument adhere to the surface.
2、Before using the instrument, set the speed control knob to the minimum position and turn off the power switch.
3、If the motor does not turn on after turning on the power switch, check if the plug is properly connected and if the fuse is blown (this should be done with the power off).
4、In order to ensure good balance and avoid excessive vibration during operation of the multi-tube vortex mixer, all test tubes should be evenly distributed when placed, and the solutions in each tube should be roughly equal.
5、Turn on the power, turn on the power switch, and the indicator light will turn on. Slowly adjust the speed control knob to the desired speed.
6、This instrument should be properly stored in a dry, ventilated, and non-corrosive gas environment. During use, do not allow the liquid to enter the core to avoid damage to the components.
