Need help?Do you have a question about the Four E's Scientific VM112B and is the answer not in the manual?
The Four E's Scientific Mini Vortex Mixer, model VM112B, is a laboratory instrument designed for shaking test tubes. It conforms to international safety regulations for laboratory instruments and is intended for use on a non-slip surface.
The primary function of the VM112B is vortex mixing, which involves shaking test tubes. To initiate shaking, a user gently pushes a test tube into the soft attachment. Shaking ceases as soon as the test tube is lifted out. The device is powered via a USB interface, requiring a power adapter plugged into a socket and connected to the Micro-B interface. When the instrument is powered on, its Type-A USB interface can also be used to charge external devices such as mobile phones or tablets.
The VM112B features a Power Switch to turn the instrument on and off. It includes an LED light indicator whose color matches the color of the silicon top (available in Blue, Orange, and Green). The LED lights illuminate when the motor is running. Users must always use covered test tubes to prevent splashing, as overfilling with liquid can cause the medium to splash out. The device is not suitable for manual operation and should only be used on a non-slip surface. When operating the shaker, users must select and wear appropriate personal protective equipment according to the mixing hazard category to mitigate risks from squirting liquids and projectile parts. Only closed test tubes should be used. Users should also be aware of the risks associated with using inflammable materials or applying excessive trigger contact pressure to glass equipment, which could lead to breakage. The shaker should only be used with materials or mixtures known not to react dangerously to the energy produced by shaking, including extra energy generated by solar radiation. The motor is not designed for continuous long-term operation, as this can lead to overheating or burnout. If the appliance begins to slide, the soft stand feet should be wiped with a damp cloth.
The Mini Vortex Mixer is designed to be maintenance-free and should not be opened by the user. Its components are subject only to natural wear and tear and their statistical failure rate. For cleaning, only cleansing agents approved by the manufacturer should be used. Electrical devices should not be immersed in cleansing agents. Before using any cleaning or decontamination method not explicitly recommended, the user must confirm with the manufacturer that the method will not damage the instrument. Recommended cleaning agents for specific materials include:
