Ultrasonic Cleaning Application


Since 1973, Ralsonics has been supplying ultrasonic cleaning equipment of all sizes spanning 15 industries. Our equipment is known for its reliability. We fully understand the requirements and processes of our customers before specifying any equipment for use. Owing to over four decades of experience in ultrasonic cleaning, we have learned and developed best practices for cleaning components in each industry.

Pharmaceutical industry

In the pharmaceutical industry, it is critical to remove all contaminants, mold, bacteria and toxic chemicals from equipment components periodically. Furthermore, preventing cross-contamination between different batches of drugs manufactured on the same equipment is necessary. The US FDA continually harps on repeatable cleaning techniques and validation to ensure the quality of drugs produced. Any cross-contamination can be very damaging to the health of consumers, potentially leading to significant loss of revenue due to product recalls and lawsuits.


The conventional techniques like hand cleaning, solvent cleaning and pressure washing are ineffective and time-consuming, especially when the components are intricate or have hard to reach places. Ultrasonic cleaning is a low-cost, eco-friendly and extremely effective technique for cleaning pharmaceutical parts.


Ralsonics’ ultrasonic cleaners are well known in the industry to provide ultra-fast and thorough cleaning for pharmaceutical tools and equipment ranging from filling valves to pill punches. Ralsonics has a large range of products (multistage cleaners, emission free vapor degreasers, ultrasonic cleaners), catering to every possible component that needs to be cleaned in the pharmaceutical industry.
