Ultrasonic Cleaning – More About Baskets and Fixtures

This blog is in response to recently received reader questions regarding the best designs for baskets and fixtures used in ultrasonic cleaning applications.  The blog Reader Questions – Baskets for Ultrasonic Cleaning addressed previous questions.  Today’s question concerns the use of metallic fasteners in the construction of baskets and fixtures to hold parts for ultrasonic cleaning. The …

Water – De-Ionoized – Right and Wrong

This blog explores some common mistakes made in the application of de-ionization hardware.  Although a properly engineered and installed de-ionization system will prevent these potential mistakes at the start, post-installation modifications by those less knowledgeable about de-ionizing technology don’t always respect good design practices. Temperature Limits – In general, de-ionization systems are not intended to …

Water – De-Ionized Water

Next to water filtration and “softening,” de-ionization is probably the next most common water treatment.  Ions in water interfere with many cleaning processes and cause water spots on drying after rinsing.  The common measure of the amount of ions in water is “resistivity.”  The more “resistive” water is, the less ions it contains.  Water from a municipal …

Metrology – Concepts in Practice

Preceding blogs on metrology have introduced some basic concepts which can serve as food for thought.  Today, I would like to give you a couple of examples of the practical application of the concepts discussed so far in industrial cleaning applications. Monitoring Contaminant Removal – Everyone wants to know how long it takes for a …

Metrology – Accuracy and Scale

No matter what is being measured, it is critical that the measuring instrument chosen be capable of providing an accurate and repeatable measurement of whatever needs measuring.  It sounds simple – – but isn’t.  In general, the larger the scale the less accurate an instrument becomes.  Let’s use weight as an example. Weighing devices come …
