_ Elaine, Why is it not good to put a glass beaker resting on
the bottom of the ultrasonic. I have been doing this for many
years and have had no problems----yet. Ron

hi ron putting any thing on the bottom of your ultrasonic
damages the transducers, you will be better off hanging it in
some sort of basket or tray etienne

Hi Ron,

It is ‘frequent’ practice to put a ring or chain on the bottom
of an ultrasonic but it is not ‘good’ practice. Two reasons
really:

  1. The ultrasonic action (“cavitation”) causes the jewelry to
    vibrate on the tank bottom and this often can cause tiny little
    scratches to the jewelry.

  2. For most (not all) ultrasonic cleaners, the tranducers (which
    are the parts that cause the cavitation, i.e. they transform
    electrical energy into ultrasonic energy) are glued to the
    underside of the tank. When there is excess sediment or lots of
    jewelry or beakers whatever placed on the bottom of tank, it
    causes the transducers to work too hard and vibrate. They can
    literally shake themselves loose from the tank. This is a
    common repair we have to make.

It’s best to get a ring rack, or basket, or something that can
be suspended from the top/sides of the cleaner so that nothing
touches the bottom. Also be sure to clean out the ultrasonic on
a regular basis so there are no accumulations of dirt or
polishing compound, etc. on the bottom.

Also be sure to keep your ultrasonic cleaner filled to the
proper level which is about 1" from top of the tank. There are
automatic fillers (very inexpensive) that make it easy to keep
the level topped off.

These practices will allow you to get the best cleaning and
longest life from your ultrasonic cleaner. And of course use a
cleaning solution that is recommended specifically for
ultrasonic cleaning.

I hope that helps? :slight_smile:
