Features: 1. This instrument uses an electric motor to drive the magnetic steel, and drives the ptfe agitator with magnetic steel in the container through the magnetic field of magnetic force line to complete the stirring task. 2. This instrument has high stirring efficiency and adjustable speeds (stepless speeds regulation), which can be used for stirring solutions with different concentrations. 3. It can also be mixed in a sealed container, its main features are large power and remarkable stirring effect. 4. Low noise and low vibration design, there is no boring noise to bother others, and the mixing is safe and easy to operate. 5. Widely used in colleges and universities, environmental protection, health and epidemic prevention, petrochemical, metallurgy, medicine and other industries of scientific research and production. Specification: Item Type: Magnetic Stirrer Material: Plastic Optional Type: EU Plug 100-240V, US Plug 100-240V Stirring Power: 25W Mixing Speeds: 0-2400 RPM Stirring Capacity: 1000ml Size: Approx. 12 x 12 x 2.4cm / 4.72 x 4.72 x 0.94in Package List: 1 x Magnetic Stirrer 1 x Magnet 1 x Adaptor Usage: The power socket shall use a 2-hole safety socket and must be properly grounded. First please check whether the random accessories are complete, then install the fixture, put the beaker in the center, add the solution and put the agitator. Using Step: 1. Plug in power supply. 2. Turn on the power switch. 3. Adjust the speeds control knob, from slow to fast to the required speeds, do not allow the high speeds start, so as to avoid the agitator out of sync. Note: 1. The machine may suddenly lose control when in use, check whether the external load has short-circuit or circuit breaking phenomenon. 2. When the machine is in use, errors may occur and system failure may be caused when it is out of control. Please install external protection circuit (such as leakage protector, air opening, etc.). 3. When working, the machine should be placed on a stable and firm work table, never put on flammable, explosive and temperature resistant work table. 4. The machine is strictly prohibited to be used in places with inflammable and explosive gases, corrosive gases and steam emission. 5. This product is a common instrument product, not explosion-proof, can not be used for human body, military, rescue and other working conditions.
