Note:Ultrasonic Cleaning Machines are shipped WITHOUT beakers. We recommend ordering 2 beakers with each machine. For sanitary reasons, it is advisable to clean only one earmold in a beaker at a time.
It is recommended to use these pyrex beakers with ultrasonic cleaning machines. First place the earmold into the pyrex beaker, then add cleaning solution into the beaker. The beaker is then placed into the tank of the ultrasonic cleaning machine, which contains 1 inch of cleaning solution at all times. This method conserves cleaning solution and helps defer the cost of the beakers.
