1. Definition and working principle of microplate oscillator 1. Definition: Microplate oscillator is driven by a DC brushless motor and is used to mix and oscillate solutions in microplates such as enzyme plates and cell culture plates. equipment. 2. Working principle: (1) Piezoelectric effect excitation: The microplate oscillator works based on the principle of piezoelectric effect. When an external voltage is applied to a microplate made of crystals with good piezoelectric effects, it will cause some parts of the microplate to deform, thereby stimulating vibration of the microplate. (2) Microplate vibration: The vibration of the microplate is a key step in generating frequency signals. When vibrating, the surface of the microplate will generate a piezoelectric signal, which will vibrate repeatedly to form a specific frequency. The vibration characteristics can be adjusted through the thickness, pore size, material, etc. of the microplate. (3) Frequency output: Use the resonance loop to extract the frequency signal generated by the microplate, and achieve signal output by matching the input circuit and the resonance loop.

2. Hardware components of the microplate oscillator 1. Brushless DC motor: The microplate oscillator uses a brushless DC motor as the power source. This motor has the characteristics of low noise, low interference, and maintenance-free, and can provide stable and Adjustable oscillation frequency. 2. Control system: Microplate oscillators are equipped with advanced control systems, usually including microprocessors or PID controllers, for precise control of the oscillation speed, time and temperature (for constant temperature oscillators). These parameters can be set and adjusted according to experimental needs. 3. Microplate holder: There is a special microplate holder on the oscillator, which is used to fix and support microplates (such as enzyme plates, cell culture plates, etc.). These racks often feature easy-to-operate spring-loaded mountings that allow for quick installation and removal of microplates. 4. Display screen: Most microplate oscillators are equipped with LED digital tubes or LCD displays, which are used to display the current oscillation speed, time, temperature and other parameters in real time, allowing users to observe the operating status of the equipment. 5. Shell and structure: The shell of the microplate oscillator is usually made of strong and durable materials and has good dust-proof, waterproof and vibration-proof properties. The internal structure is compact and well laid out to ensure the stability and durability of the device.

3. Functional features of microplate shaker 1. Adjustable speed and time: Users can set and adjust the speed and time of oscillation according to experimental needs. Generally speaking, the speed range is between 300~1400rpm (or wider), and the timing range can reach more than 99h59min. 2. Oscillation amplitude and mode: Microplate oscillators usually use horizontal rotation or circular oscillation to mix and oscillate. The oscillation amplitude can be adjusted as needed, generally around a few millimeters. 3. Temperature control (for constant temperature oscillators): The constant temperature oscillator also has a temperature control function, achieving precise temperature control through a combination of film heating and PID intelligent temperature control technology. The temperature setting range is usually wide (such as 0℃~100℃), and the temperature control accuracy can be within ±0.5℃. 4. Other functions: Some high-end microplate oscillators also have other additional functions, such as independent timing mode, multi-point operation function, automatic preheating function, automatic power-off recovery function, and built-in software and hardware dual over-temperature protection devices.

Microplate shakers play an important role in the laboratory with their unique functions and wide range of applications. With the continuous advancement and innovative development of science and technology, microplate oscillators will continue to move towards intelligence and automation, providing scientific researchers with more convenient and efficient experimental tools.
