How to choose a water bath correctly

Water bath is mainly used in the laboratory for distillation, drying, concentration, and temperature staining chemicals or biological products, can also be used for constant temperature heating and other temperature tests, is biology, genetics, virus, aquatic products, environmental protection, medicine, health, laboratory, analysis room, education and scientific research tools
.
Different models of water baths are slightly different in product quality, temperature control stability, and functional diversity, generally speaking, product selection can be done from the following aspects: 1.
Temperature control range The temperature display of the constant temperature water bath box generally has two kinds of pointer and digital display, which can automatically control the temperature
.
The quality of its temperature control effect has a lot to do
with the design of temperature sensors and temperature control systems.
According to the temperature control range, the constant temperature water bath can be divided into ordinary water bath, low temperature constant temperature tank and ultra-low temperature constant temperature tank
.
2.
Temperature control accuracy Some experiments have high requirements for temperature range, so more accurate temperature control
is required.
The ultra-high-precision constant temperature water bath has fine temperature fluctuation control, which can reduce the impact of temperature fluctuations on the experiment, which is deeply loved
by users.
In addition, the water in the thermostatic water bath is usually warmer than the water temperature in other places during the heating process, which will cause the water temperature in the sink to be uneven, in order to alleviate this situation, you can choose a water bath with a stirring device
.
3.
The water bath volume constant temperature water bath can be divided into small constant temperature tank, medium constant temperature tank and large constant temperature tank
according to the volume.
According to the shape, there are desktop and vertical type
.
You can choose the constant temperature water bath with the corresponding volume according to your experimental requirements and scale
.
4.
The main structure of the instrument material constant temperature water bath is composed of
box, inner tank, panel, beaker ring cover, shelf, electric heating tube, and intelligent digital temperature controller.
At present, the better quality water bath is basically made of stainless steel water tank and lid, which has good
corrosion resistance.
The chassis is made of cold-rolled steel plate, which is strong and durable
.
5.
The constant temperature water bath with excellent safety performance should be equipped with a variety of safety protection functions: for example, water shortage anti-aircraft burning, water shortage immediately cut off the safety device; High or low temperature alarm; Maintenance-free pressure/suction pump, pump pressure and flow automatically adapt to external loads, etc
.
In addition, maintenance can also extend the service life of the water bath: digital display constant temperature water bath maintenance and repair: 1.
The power should be turned off
after use.
2.
The inside and outside of the box should be kept tidy
frequently.
3.
If it is found that the indicator light is not on, turn off the power first, unplug the plug and pounce to disassemble the plug board on the right side, if the fuse or indicator bulb is damaged, it can be replaced with the
same specification.
4.
In case of constant temperature control failure, it means that the sensor on the controller is out of order, and it can be used
after replacement.
