Orbital oscillator

Orbital oscillator, a precision vibration equipment widely favored in the field of laboratory scientific research, has become an indispensable assistant for many researchers due to its unique working principle and wide range of application scenarios. It not only transcends the limitations of traditional mixing methods, but also leads an innovation in laboratory operation methods by cleverly applying the principles of centrifugal mechanics.

1. Working principle The orbital oscillator uses the driving force generated by the motor to convert the rotational motion into an elliptical trajectory swing of the sample in the horizontal direction through a specific mechanical structure. This swing method ensures that the sample is vibrated evenly and stably while avoiding excessive shear force or impact force, thereby protecting the integrity of the sample and the accuracy of the experimental results.

2. Features and advantages 1. High stability: The output frequency stability of the orbital oscillator is very high, and its stability can reach 1e-11 or even higher. This high stability is mainly due to the reference frequency source with higher stability inside the oscillator, such as crystal oscillator, ferrite oscillator, etc. 2. Broadband oscillation technology: Using wide-band oscillation technology, the number of components of the orbital oscillator is smaller. The size and power consumption of the entire device are smaller than other types of oscillators, making it more suitable for embedding into microcircuit chips. 3. Strong anti-interference: The internal phase-locked loop structure with self-correction mechanism can effectively resist external noise and interference and maintain the stability of the output frequency. This makes orbital oscillators more widely used in noisy environments such as radar, communications, and medical care. 4. Wide range of applications: Orbital oscillators are not only suitable for vibrating and mixing liquid and solid samples, but are especially suitable for experiments such as cell culture and microbial culture. They also have important applications in fields with high precision requirements such as frequency measurement and synchronous communication. .
