SHA-2A low-temperature constant temperature water bath oscillator

SHA-2A low-temperature constant temperature water bath oscillatorAlso known as a cryogenic water bath constant temperature oscillator, it is a biochemical instrument that combines a temperature controlled constant temperature water bath and an oscillator. It is mainly suitable for the oscillation cultivation of various liquid and solid compounds such as biology, biochemistry, cells, and bacterial strains in various universities, medical, petrochemical, health and epidemic prevention, environmental monitoring and other scientific research departments.

Its main features are:

A: Double digit temperature display and precise digital display of oscillation frequency control.

B: There are small waves when oscillating, but no splashing waves.

C: Temperature control and oscillation are respectively equipped with digital timing.

D: The universal spring bottle rack is particularly suitable for the cultivation and preparation of biological samples for various comparative experiments.

E: Frequency controller speed regulation, smooth operation, easy and safe operation.

F: The inner cavity is made of 304 stainless steel, which has good corrosion resistance.

G: The refrigeration system adopts a fully enclosed compressor.

Main technical performance:

Usage:

1. The instrument should be placed on a sturdy workbench, with a clean and tidy environment, ventilation and dryness, and convenient water supply and drainage.

2. It is best to turn off the power switch before using the instrument.

3. Packaging test bottles: Pay attention to even distribution

Pay attention to not filling too little liquid to prevent shaking of the test bottle.

Pay attention to sealing the bottle mouth to prevent water droplets from dripping into the test bottle.

4. Connect the external power supply, turn on the power switch, and the indicator light will turn on.

5. Select constant temperature:

When using, pay attention to adding water first, so that the heating tube is completely submerged in water. The amount of water added should be determined according to the required amount, but it is never allowed for the heating tube to be exposed outside the water. Try to put water in 2/3 of the water tank, turn on the power, and turn on the power switch. At this time, the temperature displayed on the digital display is the indoor temperature. Press "SET" to enter the set state of the digital display, press ▲ to increase the set temperature, and press ▼ to decrease the set temperature After setting the temperature, press "SET" again, and the temperature control meter will enter the time setting state. If there is no need for temperature timing, select "0". Press "SET" again, and the instrument will display the actual temperature At this point, the temperature control meter will enter its normal working state. When the temperature rises to the desired set value, the temperature control meter will automatically enter the constant temperature state. There may be a slight overheating when using the temperature control meter for the first time, but the overheating phenomenon will be eliminated when entering the constant temperature state for the second time. When the temperature control meter enters the constant temperature state, no operation is required, and the temperature will automatically remain constant Try to use it for as long as possible after normal use, so that the temperature difference in the equilibrium state is small.

6. Select the oscillation frequency and timing, and set the time only when the time/speed gauge stops by pressing "stop". Otherwise, it is invalid. If there is no need to set the timing, select "0" and set the oscillation frequency according to the desired speed.

7. The "oscillation switch" indicator light is on. If it is a dual function oscillator, the switch indicator light can be used to select reciprocating or rotating as needed.

8. Before each shutdown, all switches should be in a non working state and the power should be cut off.
