99-1A high-power constant temperature magnetic heating stirrer is widely used in various pharmaceutical factories, biological products research institutes and other scientific research units, and is a tool required by the personnel in the packaging room.
1. Introduction
The 99-1A high-power constant temperature magnetic heating stirrer is an early product launched in the domestic market.
The product has passed the repeated tests and practices of the Beijing Institute of Biological Products of the Ministry of Health. It is a relatively satisfactory agitator. The characteristics of the instrument: high power, low power consumption, no open flame, no noise, permanent magnet DC motor, long service life, no Rusty, can stir 10000 ml of solution to achieve satisfactory results.
2. Performance
1. Power supply: single-phase AC 220V±10V50HZ
2. Motor power: 40W
3. Speed: stepless speed regulation
4. Speed range: starting ~ 2600 rpm
5. Constant temperature range: room temperature~100°C±1°C
3. How to use:
When using this instrument, please first check whether the random accessories are complete, put the beaker to be stirred in the stainless steel
In the middle of the steel workbench, add the solution, put the stirring bar in the beaker solution, then plug in the power plug and temperature control probe connected to the instrument, then turn on the power and turn on the power switch, and the indicator light will start to work. When stirring at constant temperature, First turn on the heating switch, turn the setting measurement switch to the setting end, turn the selection knob to set the temperature, and then turn the switch to the measuring end. When the set temperature is higher than the actual temperature, the green light is on to indicate that the heating is working. When the green light is off When the red light is on, it indicates that it is in a constant temperature state. The speed is gradually adjusted from low speed to high speed, and high speed is not allowed to start directly, so as to avoid the agitator being out of sync and causing jumping. It cannot be heated when it is not stirring, and the power should be cut off when it is not working. To ensure Safety, please connect the ground wire when using, the instrument should be kept clean and dry, and the solution is strictly prohibited from entering the machine, so as not to damage the machine parts.
4. Matters needing attention:
1. When you find that the stirring is jumping or not stirring, please cut off the power and check whether the bottom of the beaker is flat and whether the position is correct. At the same time, please measure whether the current voltage is between 220V±10V, otherwise the above situation will occur .
2. Generally, the heating time should not be too long. Intermittent use can prolong the service life.
3. It can work continuously at medium speed, and it is better to use intermittently at high speed.
