Overview
The OBCEA series of multi-point magnetic stirring water bath Thermostatic bath is a combination device under the LABTOP brand, consisting of a transparent open Thermostatic bath and a multi-point Magnetic Stirrer. The device precisely controls the liquid temperature in the bath through the Thermostatic bath, and uses the multi-point Magnetic Stirrer to strongly stir multiple samples placed in the transparent bath. Its large opening design is compatible with a variety of sample containers, combined with precise temperature control, to ensure accurate and uniform sample temperature.
Features
1, waterproof operation panel, highlight four LED display, display accuracy 0.1 ℃, can indicate heating, cooling, circulation, external temperature control and other operating status.
2. Using Primary PID Control Technology, Temperature Stability up to +/- 0.05 ℃.
3, with single point Adjustment, easy to calibrate specific temperature points.
4. Equipped with a powerful immersion pressure suction pump, the liquid in the tank can be stirred horizontally and vertically to ensure uniform temperature; the large open bath is designed to accommodate multiple samples.
5. Provide two-level Safety protection: the first level is low level protection, the second level is high and low temperature protection; the alarm code is directly displayed, and the buzzer alarm sound can be set.
6. Three operation modes are optional, and support automatic operation on power (continue to run after accidental power failure recovery).
7. Magnetic stirring Each station is equipped with an independent DC brushless motor, providing low noise, long lifespan, and high efficiency.
8. Magnetic stirring Each station adopts independent high-performance magnets, which are resistant to high temperature, corrosion resistance, strong magnetic field and strong stirring force.
9. Magnetic stirring Each station can be timed and timed (optional function) to assist in the monitoring of the experimental process.
10. Magnetic stirring can be set up to rotate, reverse and reverse alternately (optional function).
11. Magnetic stirring digital display channel and actual Rotation speed, knob setting parameters, easy and fast operation.
12. Equipped with self-diagnosis function, malfunction information is displayed when equipment malfunctions, making it easy to judge.
13, optional stainless steel chilled down coil, external tap water or external cooler, to achieve high temperature cooling and room temperature and below temperature control.
14. Optional external solenoid valve can automatically control the switching off of external cold sources to achieve automatic cooling and low temperature control.
Principle
The device heats or chills down the liquid in the bath through a heating element in the Thermostatic bath and an optional chill down system such as a chill down coil, and uses an intelligent PID controller and PT100 temperature sensor for precise temperature control and stabilization. At the same time, the multi-point Magnetic Stirrer drives the high-performance magnet swirl/spin through an independent DC brushless motor to generate a swirl/spin magnetic field, which drives the magnetic stirrer placed in the sample cup in the bath to synchronize the swirl/spin, thereby stirring multiple samples to uniformly heat the sample and promote reaction or mixing.
Notice
* When you need to control the temperature at or below room temperature, you need to choose the chill down plate + low temperature chill down circulator + insulation pipe, or choose the external control solenoid valve + chill down coil + insulation pipe + tap water.
* The "*" in the model indicates that external refrigeration equipment is required. Different external refrigeration equipment has different minimum temperatures.
* Permissible Ambient Temperature is 5~ 32 ℃, the allowable relative humidity is 80%.
* Equipment supports continuous operation, but must be used under permissible environment conditions.
