Ultrasonic Cleaner Test: The Basics

Over the decades, cleaning methods for medical instrumentation have changed. Technology has developed to create equipment that can address of the medical equipment of today. Equipment cleaners must now be able to handle the needs of smaller, finely made, complex instruments. Today’s medical equipment features hinges and fine jointures. The ultrasonic cleaner test is one such means of ensuring the proper levels of clean are reached by machinery employed in this fashion.

Effective Cleaning

The latest ultrasonic cleaners prove to be effective in cleaning various instruments. They use a combination of high frequency sound (ultrasonic) waves and enzymatic detergents specifically formulated to break down any organic material present on the instruments. Among the targets are the usual suspects:

  • Bacteria
  • Contaminants
  • Dirt
  • Grease
  • Grime
  • Oil
  • Toxins

Classified as Class 1 medical device (mechanical cleaning) by the FDA, they are designated as suitable for cleaning of fine parts but are not suitable for sterilization. This device is fast and easy to operate. A preferred method of cleaning medical instruments, it, nonetheless, requires testing to determine whether it is operating effectively. Medical professionals, in fact stipulate the timing of such tests. They feel it essential to administer tests at minimum weekly but preferable daily and in the following instances:

  • Before initial use
  • Following a major repair
  • Weekly if in constant use
  • After even routine maintenance

To make certain this occurs companies have come up with an ultrasonic cleaner test.

Products for cleaning these machines vary. However, they all need to address certain factors that determine the overall effectiveness of the ultrasonic cleaner. These are:

  1. Enzymatic detergent concentration/activity
  2. Wash cycle time
  3. Wash cycle temperature
  4. Mechanical action

Any issue with these factors will impact negatively on the cleaning capabilities of the equipment. The choice of the right responsive ultrasonic cleaner test will ensure detection of any improper functioning by the machine immediately, laying the basis for corrective action to occur.
