Product introduction 1. What is the accuracy and stability of temperature control? 1. Heating (by setting 37 degrees as an example) The heating rate of the shaker can be adjusted. According to the requirements of the user test, the heating rate of the shaker can be increased, and the heating rate of the shaker can be slowed down. two. What is the accuracy and stability of speed control? The start of the shaker speed is a slow acceleration process, which can effectively avoid the tipping of the test piece due to uneven acceleration. When the speed reaches the set speed, it will run smoothly at a constant speed. The tabletop shaker has a speed range of 40 rpm to 400 rpm, and the horizontal shaker has a speed range of 40 rpm to 300 rpm. When the shaker is fully loaded and the zui is running at a high speed, the shaker is now The noise is louder, and the noise is mainly the impact of the bottle.

Technical characteristics: Taking 37 degrees as an example, when the temperature rises to about 30 degrees, the heating speed of the shaker will slow down. When the temperature rises to 36 degrees, the temperature rise will be slow. The purpose of this heating method is to achieve the accuracy and stability of the temperature control. Therefore, when the temperature of the shaker is set to 37 degrees, the temperature overshoot does not exceed 0.2 degrees, and then the temperature will go down, which greatly protects the sample. safety. When the temperature of the shaker is stable, the temperature control accuracy is plus or minus 0.1 degrees.
2. Refrigeration
Refrigeration can be divided into two modes: frequent start of compressor and normally open compressor. When the temperature of the shaker is set below 15 degrees, we recommend that the compressor be normally open, which is beneficial to ensure the accuracy of temperature control. When the temperature of the shaker is set above 15 degrees, the compressor can be selected to start frequently. At this time, the stability of the shaker temperature will decrease, and there will be fluctuations within the range of plus or minus 0.5 degrees. It is also possible to select a normally open compressor such that the temperature is more stable and the temperature fluctuation range is smaller. Therefore, the choice of cooling method should be based on the actual needs of users.
Usually the table shaker can be fully loaded and the Zui high speed operation, the horizontal shaker is not more than 230 rpm at full load, (it can also run at 300 rpm). The double shaker has a higher center of gravity and is generated during operation. The centrifugal force is relatively large, and the flatness of the horizontal shaker is poor. When the full load is running, it should not exceed 220 rpm. When the shaker is not at full load, the running speed can be adjusted according to the actual situation. The control accuracy of the rotational speed of the shaker is plus or minus 1 rpm.
