Muxuan ZJB-250S Intelligent LABOratory Stirrer Touch Screen

Equipment introduction

ZJB-250S intelligent laboratory mixer adopts brushless DC motor, the casing is made of engineering plastics, the three-core processor intelligent control motherboard, TFT touch screen, overload and overcurrent protection, self-test, timing, speed memory and other functions can be preset The speed can be paused at any time, the speed is digitally displayed, the torque curve is displayed, and the forward and reverse can be switched, which is easy to operate. 

The machine has a reasonable and compact structure, ultra-low noise, and maintenance-free. The stirring speed is controlled by a microprocessor, which can instantly and effectively compensate the speed change caused by load changes and power supply Voltage fluctuations. The built-in automatic overload protection device ensures the continuous operation of the experiment with high load for a long time; the experimental application function of various types of stirring rods; the digital display of the stirring speed ensures the intuitive collection of experimental data; it can meet the correction of the stirring speed in the experiment at any time; the stable stirring speed, Competent for stirring high-viscosity media and slurries, and can be equipped with a variety of working heads of different specifications.

Application

【Material viscosity】:≤100000 cps(mPas)

[Applications]: It is suitable for dispersing, stirring and mixing materials in industries such as biology, medicine, food, ink, textile auxiliaries, cosmetics, lubricating oil, and pesticides. 

native features

Stir bar application reference for stirring experiments

1. Three-blade propeller type: used at medium and high speeds. Make the mixed medium flow axially from top to bottom, and the shear force is small.

2. Four-blade propeller type: used at medium and high speeds. Make the mixed medium flow axially from top to bottom to generate local shear force.

3. Dissolving type: use at medium and high speeds. Make the mixed medium flow radially from the top and bottom, and the strong turbulent flow and high shear can crush the particles in the liquid.

4. Centrifugal type: used at medium and high speeds. The double blades open as the speed increases, suitable for use in narrow-mouth containers. The stirring effect is similar to that of a four-bladed propeller.

5. Fan type: used at low and medium speeds. The tangential flow turbulence is small, and the heat exchange performance is good. It is used in occasions that require gentle stirring of the medium .

6. Anchor type: use at low speed. Tangential flow is created, with high shear rates at the edges. Make it difficult for the mixed medium to deposit on the container wall. Applied to polymer reaction and mineral dispersion in liquid, it is a satisfactory stirring element for medium and high viscosity fluid.
