Brix vs. Conductivity: Measuring Ultrasonic Bath Concentration

27 June 2018

Several years ago, our plant was directed to use the Refractive Index as a method of letting us monitor bath concentration during ultrasonic cleaning with your Liquinox detergent. More recently, our factory in Asia switched to Liquinox and were directed to use a conductivity measurement to monitor concentration. I decided to measure our cleaning bath using both methods and found a discrepancy -- the brix (Refractive Index) reading was slightly above 1% concentration, but the Conductivity reading was nearly 2% concentration.

Risk Based Limits and Pharmaceutical Cleaning

21 June 2018

Q. We are moving from LD50 data to ADE (PDE) limits based on HBELs. This is allowing us to eliminate disposables for low-risk products.  How do I know which can be manually cleaned and which needs to be in a washer? Can manual cleaning be validated? A. Many pharma and biotech companies have been moving to Health-Based Exposure Limits (HBELs) meaning Acceptable Daily Exposure (ADE) or Permitted Daily Exposure (PDE) limits as detergent residue limits.

Ultrasonic Cleaner for Parts and Towels

12 June 2018

I'm looking for a cleaning solution to use in our industrial ultrasonic cleaner that is similar to the old style competitor detergent. We use it occasionally for general cleaning, removal of machining oils, cleaning for high vacuum use, and to lightly etch the oxides off of copper.  If we did a pre-mix and let it sit until use, how long would the formulations last before degrading? Could we also use this mix for washing microfiber towels and foam sponges that have various waxes, polymer sealants and oils on them?
