Among the precision instruments in the laboratory, the orbital oscillator has become an indispensable assistant for scientific researchers with its unique working method and wide range of applications. It uses a motor to drive an eccentric or a swing arm to generate periodic horizontal vibrations. This vibration is transmitted to each container through the working platform, allowing the liquid or solid samples inside to be stirred softly and evenly without touching the container wall. . This method not only avoids sample contamination and damage that may be caused by traditional stirring methods, but also greatly improves the accuracy and repeatability of experiments, playing an important role in experiments in multiple disciplines.
1. Key parts constituting the orbital oscillator 1. Working platform (1) Description: The working platform is the main part of the orbital oscillator. It is usually made of solid metal and has a flat and stable surface. It is the main area for supporting and fixing experimental samples. (2) Function: On the work platform, users can install and fix various containers, such as petri dishes, flasks, test tube racks, etc., to ensure that the sample remains stable during the shaking process. 2. Oscillation system (1) Composition: The oscillation system includes key components such as motor, reducer, swing arm or swing rod. These components work together to produce horizontal and vertical vibrations. (2) Function: The motor provides power for the entire system, and the reducer reduces the motor's speed and increases the torque to ensure the stability and controllability of the oscillation. The swing arm or swing rod produces periodic swings through rotational motion, which in turn drives the entire working platform to vibrate. 3. Control panel (1) Description: The control panel is the operation center of the orbital oscillator, used to set and adjust the parameters of the oscillation. (2) Function: The control panel is usually equipped with a digital display and buttons, allowing the user to conveniently set parameters such as oscillation speed, amplitude, and vibration mode. In addition, some advanced model control panels may also have timing functions and temperature control functions to meet more experimental needs. 4. Safety device (1) Description: In order to ensure the safety of operation, orbital oscillators are usually equipped with safety devices. (2) Function: These safety devices may include emergency stop buttons, overload protectors, and anti-tip devices. The emergency stop button allows users to quickly cut off the power and stop oscillation in an emergency; the overload protector can automatically cut off the power when the motor load is too large to prevent equipment damage; the anti-tilt device ensures that the equipment remains stable during vibration to prevent accidents dump. 5. Other auxiliary components (1) Description: In addition to the above main components, the orbital oscillator may also include some other auxiliary components, such as sample fixtures, trays, anti-vibration pads, etc. (2) Function: These auxiliary parts help to better fix and support the sample and improve the uniformity and stability of oscillation. At the same time, they can also reduce the impact of vibration on the device itself and the surrounding environment.
2. Characteristics and advantages of the orbital oscillator 1. Uniform vibration: The orbital oscillator completes the vibration through the swing generated by the elliptical trajectory. The swing amplitude and frequency of the sample are relatively uniform, which can better simulate the behavior of objects under the action of earthquakes or earthquakes. state. 2. Wide range of application: suitable for vibration mixing of liquid and solid samples, especially suitable for cell culture, microbial culture and other experiments. 3. Diverse functions: Modern orbital oscillators often have timing and speed adjustment functions, which can set the appropriate oscillation time and speed according to experimental needs to improve the accuracy and repeatability of experiments. 4. Strong adaptability: usually equipped with a variety of optional trays and containers, which can adapt to flasks, petri dishes, beakers and other containers of different shapes and sizes.
3. Technical parameters of orbital oscillators The technical parameters of orbital oscillators vary depending on the model and brand, but generally include the following: 1. Speed range: such as 50-300rpm (revolution/minute), different models and brands of orbital oscillators RPM range may vary. 2. Oscillation frequency: up to about 300 swings/min, much higher than a horizontal shaker. 3. Timing function: The oscillation time can be set according to experimental needs. 4. Speed regulation function: Control the oscillation frequency by adjusting the speed of the motor.
As one of the core equipment in the laboratory, the importance of the orbital oscillator is self-evident. Its unique horizontal vibration mode not only efficiently achieves uniform mixing and rapid reaction of samples, but also lays a solid foundation for scientific research exploration and experimental verification with its wide range of application fields. From rapid mixing of chemical reagents to delicate processing of biological samples, to preprocessing of environmental samples and precise execution of medical analysis, the orbital oscillator has fully demonstrated its outstanding capabilities and extraordinary value as a scientific research all-rounder with its diverse application scenarios.
