The maneuver oscillator is one kind of raise preparation biology sample biochemistry instrument, is scientific research, the education and the production department essential test installation and so on plant, biology, microorganism, biological preparations, heredity, virus, medicine, environmental protection. The instrument is the console model, the complete machine center of gravity is low, in continuous working steady reliable, its main characteristic:

⑴ The multi-purpose springs try the bottle rest to be specially suitable do many kinds of contrast experiment the biological sample raise preparation.

⑵ Is equipped with the machinery fixed time.

⑶ stepless speed regulation, operation simple security.

⑷ HY-5A has the number to reveal the function a section oscillator, operates easily.
