Safety Instructions
In order to be able to use the appliance properly and
safely, every user must first read the operating instructions
and observe the safety instructions contained therein. Take
care of these operating instructions and keep them in a
place where they can be accessed by everyone.
The mini vortex mixer is a laboratory instrument which
conforms to the international safety regulations for
laboratory instruments.
Caution: Overfilling with liquid may cause the medium to
splash out.You should therefore always use covered test
tubes.
- The unit is not suitable for manual operation. Observe all
pertinent safety instructions and directives, as well as
work-safety and accident-prevention regulations for
laboratory use.
- The appliance must only be used on non-slip surface.
- When working with the shaker, the user must select and
wear his personal protective equipment according to the
mixing hazard category. Defective or inadequate protective
equipment can expose the user to the risk of squirting
liquids and projectile parts. For this reason, only closed
test tubes should be used.
- The user may also be at risk if inflammable materials are
used in the shaker, or if the trigger contact pressure is
too great for glass equipment or the transmitted
mechanical shaking power causes the glass to break.
- Furthermore, the shaker may only be used to shake
materials or material mixtures that the user knows will
not react dangerously to the extra energy produced by

the shaking. This also applies to extra energy generated
by solar radiation during the shaking procedure.
- The appliance is maintenance-free and must not be opened.
- The mini vortex mixer was not designed for use in
dangerous atmospheres, for mixing dangerous
substances or for use under water.
- If the appliance begins to slide, wipe the soft stand feet
with a damp cloth.
- The motor can't work continuously for a long time,
otherwise it will overheat or even burn out.

Power Switch
- Power Switch: Turn on and turn off the instrument.
- LED light: The color of the LED light matches with the
color of the silicon top (There’re 3 colors of tops available
- Blue, Orange and Green). When the motor is running,
the lights are on.
- USB interface: Power on the instrument when the power
adapter is plugged into a socket and connected with the
Micro-B interface. When the instrument is powered on,
the external devices (such as a mobile phone or tablet

4
PC) can also be charged by connecting with the Type-A
interface via a USB cable.
- Vortex mixing: The Mini vortex mixer is designed for
shaking test tubes. Gently push the test tube into the
soft attachment to start shaking. Shaking stops as soon
as you lift out the test tube.
