Characteristics and working mode of water bath constant temperature oscillator
The water bath constant temperature oscillator 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 scientific research departments such as universities, medical institutions, petrochemicals, health and epidemic prevention, and environmental monitoring.
The water bath constant temperature oscillator, also known as the water bath constant temperature shaker, uses an advance system for temperature control and LED display in this series of products. High temperature control accuracy, convenient temperature adjustment, accurate and intuitive indication, and reliable performance. The gas bath constant temperature oscillator, incubator, and studio are equipped with lighting devices for easy observation. The oscillating incubator, also known as the full temperature oscillator, uses a fully enclosed compressor with a large cooling capacity. The incubator is equipped with fans and devices to force air convection, resulting in a more uniform temperature distribution.
Adopting the principle of electromagnetic oscillation, similar to the principle of induction cookers, an alternating magnetic field is generated by the components of an electronic circuit board, and an alternating current (i.e. eddy current) is generated by cutting the alternating magnetic field lines in a stainless steel container. The eddy current causes the iron molecules on the container wall to move at high speed and irregularly, and the molecules collide and rub against each other to generate heat energy. At the same time, due to the presence of eddy currents, water molecules are subjected to electromagnetic force, which drives the liquid inside the glass container to move and achieve the effect of oscillation.
Working mode of water bath constant temperature oscillator
1. Cyclotron oscillation: This working method is also called circular oscillation, which rotates 360 ° in a horizontal plane. For example, when working in this way, the liquid being oscillated in a vortex state inside the container to achieve a uniform effect.
2. Reciprocating oscillation: As the name suggests, it means oscillating back and forth during oscillation, using inertia to oscillate the sample. Why use this oscillation method? Because when the viscosity of the liquid is high, this oscillation method works much better than cyclotron oscillation.
3. Dual function oscillation: It combines two modes of oscillation: cyclotron and reciprocating oscillation. Depending on the characteristics of the sample and the requirements of the work, one can choose any working method on their own.
