Ultrasonic Cleaner Baskets

There are two key reasons why you need an ultrasonic cleaner basket when cleaning parts or mixing samples:

  1. To protect the cleaner and parts from damage caused by direct contact
  2. To hold parts when immersing and removing them from the solution

Expanding on the first point, generator-powered transducers mounted to the ultrasonic tank cause the tank to vibrate at ultrasonic frequencies producing cavitation cleaning action.  In most cases, the bottom of the tank is the vibrating surface.  Parts in contact with this surface can damage the transducers.  In addition, if parts are in contact with the tank bottom they can abrade the metal, somewhat like a drill, and eventually may wear a hole in the tank.   Note:  A leak may irreparably damage tank electronics.  This is another good reason to use baskets.

Note that basket dimensions are slightly less than tank dimensions.  Parts to be cleaned must fit inside the basket and must be completely submerged in the cleaning solution.  When selecting an ultrasonic cleaner make sure to check the inside dimensions of the basket.

Ultrasonic Cleaner Basket Design

Elma ultrasonic cleaning baskets are fabricated of stainless steel. They come in several configurations broadly classified as:

  • Open Weave Baskets (sides and bottoms) commonly used with industrial type cleaners such as the Elmasonic X-tra Basic and TI-H series industrial cleaners
  • Solid-Side Baskets with Mesh Bottoms found on benchtop E, S, P series ultrasonic cleaners. These baskets have plastic coated handles for insulation, allowing parts to be comfortably removed from hot cleaning solution.
  • Fine-Screen Immersion Baskets are used to hold small parts such as fasteners and screws. These small cylindrical baskets can be positioned in larger baskets or placed inside 600-mL or 1000-mL glass beakers.
  • Plastic Baskets may be called for when cleaning extremely delicate parts such as glass tubing and gemstones that may be damaged when in contact with stainless steel. Note that by its nature plastic slightly inhibits cavitation action.
