Overview
The HWCL-3 thermostatic magnetic stirring bath is a laboratory equipment produced by GREATWALL, which combines thermostatic heating and magnetic stirring functions. It can be used as both a water bath and an oil bath. The bath has a strong magnetic stirring system, which is designed to provide a uniform heating and stirring environment for chemical reactions.
Features
1. The heating device made of 304 stainless steel has good durability.
2. The magnetic stirring mechanism drives the stirrer in the tank to swirl/spin synchronously, so that the solution in the bath is swirl/spin and heated evenly.
3. High performance brushless DC motor, stable performance, can be used continuously.
4. Using high-temperature magnets, continuous use at 300 ° C does not lose magnetism.
5. The temperature control adopts PID mode, and the temperature control accuracy is high.
6. Adopt key input and digital display for easy operation.
7. The HWCL-3 model has built-in dual Sensors, and the temperature in the bath and the temperature in the reaction vessel can be converted to display.
Principle
The device heats the medium (water or oil) in the bath through the built-in heater, and realizes precise temperature control through the PID temperature Control system. At the same time, the magnetic stirring mechanism at the bottom of the device generates a swirl/spin magnetic field, which drives the magnetic stirrer placed in the bath to synchronize the swirl/spin, so as to stir the solution in the bath or in the reaction vessel to achieve uniform heating and mixing.
Applications
Chemical synthesis, biopharmaceutical, materials science, analysis and testing, teaching experiments
Standards
The product information does not mention specific compliance standards.
Steps
1. Place the device on a stable countertop and connect it to the power supply.
2. According to the experimental requirements, add an appropriate amount of water or oil to the bath as the heating medium.
3. Place the reaction vessel (e.g. flask) containing the sample into the bath and place the appropriate magnetic stirrer into the vessel.
4. Turn on the power switch.
5. Rotation speed is set by knob.
6. By pressing the button to enter the set target temperature, the device will start heating and temperature control.
7. For the HWCL-3 model, the bath temperature or the temperature inside the reaction vessel can be switched through the function keys.
8. After the experiment, turn off the power supply and clean up after the equipment is chilled down.
Notice
• Make sure the equipment is placed on a smooth, ventilated countertop for use.
• The liquid level of the heating medium (water or oil) added should be appropriate to avoid too full or too little.
• Do not dry the heating device without medium or insufficient medium in the bath.
• Please place the appropriate reaction vessel according to the size and parameters of the bath (e.g. maximum 3000ml flask can be placed) to avoid overloading.
When the equipment is working and has just stopped working, the temperature of the bath and medium may be very high. Please do not touch it directly and be careful of burns.
Before cleaning the equipment, be sure to disconnect the power supply and wait for it to completely chill down.
• Power supply voltage (1~, 110V, 60Hz or 220V, 50/60Hz) corresponding to the device nameplate identification.
