Lab Scale Vacuum Freeze Dryer (Lyophilizer) for Medical and Food

The ultrasonic vibrating rod uses the alternating period of positive and negative pressure in the transmission process of ultrasonic waves. In the positive phase, the medium molecules are squeezed and the original density of the medium is increased. In the negative phase, the medium molecules are sparse. discrete, the density of the medium decreases. The ultrasonic vibrating rod can generate ultrasonic waves evenly around 360 degrees, and the output of energy is not affected by load changes such as liquid level and temperature difference.
