The four available models, USBB-S, USBB-M, USBB-L and USBB-XL cover most of the ultrasonic baths used in the labs.

Advantages:

• High noise reduction up to 30dB(A). That means a drop in noise of 90 to 95%.
• Available in four different sizes for mostly all ultrasonic baths.
• The cover can be completely opened, so the removal of the
  basket is very easy to handle.
• There is no additional space needed to open the cover, so the
