The difference between a water bath and an air bath thermostatic oscillator

There are two main types of thermostatic oscillators: water bath thermostatic oscillator and air bath thermostatic oscillator, and the main differences are as follows:

1.The maximum temperature of the water can reach 100, so the constant temperature range of the water bath is from room temperature to room temperature, and the air bath is heated by the air due to the air blower device.

And the tightness of the instrument, the maximum is generally not more than 50, so the constant temperature range of the instrument should be a little smaller, is the room temperature to 50, can achieve accurate temperature control.

2.It's the principle of constant temperature is different. The constant temperature heating of the water bath thermostatic oscillator is heated by the heating tube, the principle of which is the principle of the water bath, water is injected into the sink, heated with the heating tube, and the effect of heating water and constant temperature is achieved through the control of the heating tube; The air bath thermostatic oscillator mainly uses air heating, realizes the uniformity of temperature through the air blast device, and the heating power is much smaller than the water bath oscillator, and the highest heating temperature of the conventional air bath thermostatic oscillator can only reach 60, and the uniformity of temperature is relatively high, and it is mainly used in the experimental environment without water.

Gas bath thermostatic shaker.

It is based on air as the heating medium, so the constant temperature range room temperature to 50, z high up to 60, it is not the same as the design of the water bath thermostatic oscillator, the working cavity of the air bath thermostatic oscillator is all designed without waterproof function, in the process of use, if you add water to the air bath thermostatic oscillator, the whole machine will have the possibility of scrapping.

Unlike mixers, mixers are used to mix two or more noisy or simple substances together for the purpose of mixing uniformly, such as vortex mixers, magnetic or electric mixers. The constant temperature water bath oscillator is mainly for the purpose of dynamic lifting pants constant temperature culture. As for the water bath, it is a constant temperature method.

Water bath thermostatic shaker.

First of all, clamp the sample that needs to be shaken and cultured on the stainless steel spring and lower fixture, turn on the power supply (plug the randomly matched power plug into the power socket of the machine and the external power socket respectively), close the oscillation source switch (lift down) indicator light, indicating that the power supply in the machine has been turned on, and select the timer to the time you need. You can choose the oscillation speed to be within 300 rpm of the starting according to your actual needs. Turn on the temperature control switch, the display evolves from the actual temperature in the instrument container, press the "set" button to make the digital tube on the right of the decimal point of the display flash, set the required preset temperature at this time, press the increase, press the decrease.

Press the "set" button again, and the data will be displayed as the actual temperature in the instrument container. If the temperature of the inner device of the instrument is obviously inconsistent with the displayed temperature, make the following adjustments: press and hold the "set" button, when the display appears as "e release (e is the advance amount control, it has been adjusted before leaving the factory, please do not adjust it by yourself), and then press the "set" button, the number display appears (there is no English letter at this time), press Increase the temperature, press Reduce the temperature (for example:

If the actual temperature in the instrument container is greater than the displayed temperature, the deviation between the two is required), until calibration. Press the "set" key again, and it will be displayed as "p is the proportional band, which has been adjusted before leaving the factory, please do not adjust it yourself). Press "set" again to display the temperature in the instrument container.

The "out" light indicates that the preset temperature is higher than the temperature in the instrument and is in a heated state.

How to use the thermostatic shaker in the water bath:

First, add a certain amount of water to the tank (2 cm of water into the vibrating plate is appropriate), and clamp the sample to be shaken and incubated on the tray fixture. Turn on the power supply (plug the randomly matched power plugs into the power socket of the machine respectively), close the power switch (shovel down) indicator light, indicating that once the power supply in the machine is turned on, the thermostatic heating part has also entered the working state. The "red" color indicator light in the temperature control part indicates the heating work, and the "green" light indicates that the heating stops, and the degree displayed by the number is the actual temperature in the workshop, and the number is the preset temperature.

If you need to control the temperature in a certain area, you only need to select the number to a certain temperature to be controlled, and the temperature can be controlled. At this time, the timer will first reach the working time you need, or select the normally open "no" position, the oscillation part can work, you can choose the oscillation speed to 0-300 revolutions range according to actual needs.

Set temperature: Press the SET button to set or view the temperature set point. Press the set key digital tube characters to start flashing, indicating that the instrument has entered the set state, the key setting value increases, the key setting value decreases, the long press key or key data will change rapidly, and the set key instrument returns to the normal working state and the temperature setting is completed. (If the thermostat is an intelligent type, a temperature control manual is attached).

When switching between two functions, adjust the speed knob to the minimum

Precautions: The instrument shell should be properly grounded to avoid accidents.

It is strictly forbidden for all kinds of solutions to enter the control room to avoid damage to the host.

It is strictly forbidden to heat without water in the water tank, so as not to burn out the heating pipe and cause oil leakage.

Summary. The air bath oscillator can be replaced with a sound oscillator. A sound oscillator is a device capable of generating sound vibrations that can be used to produce an effect similar to that of an air bath oscillator.

In addition, similar devices such as audio shakers or ultrasonic oscillators can also be used in place of air bath oscillators.

Can you add, I don't quite understand it.

When we use an air bath oscillator, it uses the airflow to create vibrations that make the body feel the vibration effect of Bifeng to comfort. Sound oscillators are also capable of generating vibrations, but deniers are different in that they do not use air flow to produce vibrations, but rather use sound to produce vibrations. Sound oscillators can often produce sound vibrations by connecting to an audio device, such as to a phone or computer.

Ultrasonic oscillators achieve a similar effect by generating high-frequency vibrations. Therefore, these devices can be used in place of air bath oscillators to provide a similar vibration effect.

The water bath oscillator is mainly used in colleges and universities, medical, petrochemical, health and epidemic prevention, environmental monitoring and other scientific research departments for biological, biochemical, cell, strain and other liquid and solid compounds of oscillation culture. It has the characteristics of reasonable structure, easy operation and high stability and high performance, and is an ideal equipment for experimental staff.

To put it simply, it is to use water to stabilize the vessel, and the utensil is clamped on the spring of the oscillator to oscillate to achieve the function of constant temperature oscillation.

The principle of electromagnetic oscillation, similar to the principle of induction cooker, is to generate alternating magnetic field through the components of the electronic circuit board, and the alternating current (i.e., eddy current) is generated by cutting the alternating magnetic field lines of the stainless steel container, and the eddy current makes the iron molecules on the wall of the container move irregularly at high speed, and the molecules collide with each other and rub against each other to produce heat energy.

1. Cyclotron oscillation: This working mode is also called circular oscillation, which rotates and oscillates 360° on the horizontal plane, for example, working in this way, the liquid being oscillated is in a vortex state in the container to achieve a uniform effect.

2. Reciprocating oscillation: As the name suggests, it is a round-trip oscillation when oscillating, and the inertia is used to oscillate the sample. Because when the liquid is thicker, this oscillation is much more effective than whirlpool oscillation.

3. Dual-function oscillation: that is, it combines the two modes of gyration and reciprocating oscillation. Depending on the characteristics of the sample and the work requirements, you can choose any working mode.
