FIELD: mechanics.
SUBSTANCE: device to ensure a high-frequency vibration of tubes contains a support plate (22) for tubes (24), means to lock the rotation of the support plate relative to its axis and appliances (12, 16, 18, 20) to make plate (22) vibrate relative to the centre of rotation on the axis of plate (22). Plate (22) gets hold and centered on the elastosuspended part of this device (26) by means of two concentric bearings (28), (29) arranged one inside another. One of them is a ball bearing used to provide for oscillating motion of the above plate relative to the centre of rotation. The proposed invention allows an increase in the device life and decrease in the sample analysis time.
EFFECT: increase in the tube vibration device service life and reduction in the sample analysis time.
