1Water bath constant temperature shakerProduct Introduction:

Water bath constant temperature shaker(Also known as)Water bath constant temperature oscillator）It is a biochemical instrument that combines a temperature controlled constant temperature water bath and an oscillator. It is an indispensable laboratory equipment for precision cultivation and preparation in scientific research, education, and production departments such as plants, biology, microbiology, genetics, viruses, environmental protection, and medicine. Its main features are:①Accurate temperature control,Digital display.②There are small waves when oscillating, but no splashing waves.③Equipped with mechanical timing.④The universal spring bottle rack is particularly suitable for the cultivation and preparation of biological samples for various comparative experiments.⑤Stepless speed regulation, speed digital display, smooth operation, easy and safe operation.⑥The inner cavity is made of stainless steel, which has good corrosion resistance.

IIIWater bath constant temperature shakerinstructions:

1.Using at medium speed within the speed range can extend the lifespan of the instrument.

2.The instrument should be placed on a sturdy workbench, the environment should be kept clean and tidy, ventilated and dry, and the water supply and drainage should be convenient.

3.Before using the instrument, place the speed control knob in the smallest position and turn it off“Oscillation switch”.

4.Attention should be paid to the following points when packaging culture test bottles:①Uniform distribution;②The liquid filling amount should not be too small to prevent the test bottle from floating;③Seal the bottle mouth to prevent condensed water droplets from dripping into the bottle.

5.Inject tap water into the water tank, with the water level slightly higher than the liquid level inside the culture bottle.

6.Connect the external power supply and place the power switch in“open”The position and indicator light are on.

7.Select constant temperature:

a.setting temperature: PressSETThe key can be used to set or view the temperature setpoint. clickSETThe characters on the digital display start flashing, indicating that the instrument panel has entered the set state. Press△The key setting value increases, press▽The key setting value decreases, long press△perhaps▽The key data will change quickly, press againSETThe key instrument panel returns to normal working state and the temperature setting is completed. The heating start indicator light is on.

b.Pre set: PressSETkey3The second meter enters the inner parameter setting state. *The parameter that appears and flashes is the advance amount that stops immediately. The advance amount parameter should be carefully adjusted to reduce temperature overshoot. When the instrument controls the heating output, it will cut off heating in advance. When the temperature drops below the advance amount, it will start heating again. The output (relay) will not work within the set value and advance amount range. This can reduce the number of relay actions and extend the service life of the relay. Example: If the set value is50.0℃The advance quantity is0.5The instrument controls the heating to49.5℃When the relay is released, the temperature drops to50.0℃-0.5℃=49.5℃The relay is closed again. The larger the advance amount, the fewer times the relay will act, and if the advance amount is too large, it will reduce the control accuracy. After adjusting the advance quantity parameter, pressSETkey3The second meter returns to working mode.(Note: Pre setting is specifically set to prevent excessive temperature surge after heating stops, and generally does not require modification.)).

c.Correction of errorsWhen confirming that the value displayed on the instrument is not the correct measurement value, the displayed value can be corrected. pressSETkey3Enter the inner menu of the instrument panel in seconds, and the * parameters that appear and flash areE00Advance quantity, press againSETThe parameter where the key appears and flashes is the error correction parameter, in conjunction with△perhaps▽The key can modify this parameter. The range of error correction is-9.9℃arrive+9.9℃After the correction is completed, click againSETPress the key to exit. The correction value of the instrument when it leaves the factory is0.0，When using, it is necessary to prevent correcting instruments that display correctly to incorrect ones.

8.Select the timer and adjust the timer knob to“at regular time”perhaps“normally open”Location.

9.open“Oscillation switch”The indicator light is on, slowly adjust the speed control knobObserve the speed display screen,Raise the required speed.

10.Before each shutdown, all switches should be placed in a non working state and the timer should be set“zero”Cut off the power supply.

11.Do not use heaters when the water tank is empty. If the instrument is not used for a long time, the water in the water tank should be drained and wiped dry with a soft cloth.

4Water bath constant temperaturetableMaintenance and upkeep:

1.Proper use and maintenance of instruments can prolong their service life by keeping them in good working condition.

2.During continuous operation, the instrument should be regularly inspected every three months to check for any water droplets, dirt, or other debris falling onto the motor and control components; Check the water quality and cleanliness inside the water tank; Check fuses, control components, and fastening screws.

3.The bearings of the oscillator transmission part have been filled with an appropriate amount of lubricating grease before leaving the factory（1Number Calcium-Sodium based), during continuous operation of the instrument, lubricating grease should be added every six months, with a filling amount of approximately bearing space1/3.

4.The natural wear and tear of the instrument after long-term use is a normal phenomenon. After one year of use, if abnormal noise is found in the motor, the heating system is abnormal, the bearings in the transmission part are worn, the belt is loose or cracked, the heating constant temperature is abnormal, and the electronic control components fail……When there is a malfunction, our company will continue to provide high-quality services and assist in handling it.
