Product Details

Scientific instruments are tools for precision measurement, and their precision and reliability must be an order of magnitude higher than the object being measured. Therefore, although there are not as many components as airplanes, the systematic design is also beyond imagination. The chromatographic column, as a consumable, is a separation center, just like the heart. High pressure, tightness and flow rate stability are required. And the oven needs to be kept at a constant temperature. To prevent leakage, maintain constant temperature, pressurized flow, every link, can not be slack. For materials, seals, and fluid mechanics, a high foundation is required.

The method for checking whether the instrument leaks: pinch off the external vacuum skin tube, and observe whether the vacuum gauge on the instrument can keep the instrument leak-free for five minutes. If there is air leakage, check whether the sealing ring on each sealing joint and rotating shaft is effective. On the contrary, the instrument is normal to check the vacuum pump and vacuum pipeline.

Features:

• Stirring paddle "wear top" design, easy to replace the container;

• LCD shows the speed set value and the real value, and can switch the display torque;

• Safety features such as splash and overload protection;

• DC brushless motor, explosion-proof, long life, maintenance-free;

• Self-locking hand-tight drill chuck, no auxiliary tools, easy to operate;

• Start, run smoothly, prevent sample splash or overflow;

• Constant speed, can automatically adjust the torque according to the change of sample viscosity, maintain the set speed;

• Overload protection and motor protection: automatically cut off the circuit and alarm in case of overload, short circuit and abnormal speed to ensure safe operation;

• Silicone protective sleeve to prevent solvent volatilization corrosion drill chuck, to avoid rust;

• Stirring paddle type: 316 stainless steel stirring paddle, corrosion-resistant PTFE coating stirring paddle;

• RS232 data interface can be connected to the computer remote control and save data;
