Reducing Foam in Ultrasonic Cleaning

How do we go about reducing foam suds in our 1% Liquinox ultrasonic bath? We have 3 ultrasonic tanks in our series process. Bath 1 has the 1% solution. Bath 2 and 3 are a rinsing cascade system with RO water only. The foam is building up in tank 1 and then transfers to tank 2.

Bleach with Detergents for Disinfection?

Adding bleach to Alconox and Liquinox detergents can be done to enhance the disinfecting and oxidizing properties of these cleaners. Adding oxidizing does bring one more cleaning mechanism to the cleaning process which can be helpful if you are trying to clean dyes, pigments, heavy burned on organic residues and other residues that are labile to oxidation. You can get some disinfection, but as we will explain, you need to clean a surface first before you disinfect.

How to Clean Labware: Automated Washer Detergent

Q. Liquinox foams too much to use in the labware washer. We test for phosphate, so we need a phosphate free detergent. We need a cleaner that will clean off any testing residual on glass and plastic without leaving any interference.
A. Detergent choice for cleaning labware in an automated laboratory washer depends upon whether you use powered or liquid detergent. Click for details. For powdered detergent, use Tergajet phosphate-free low foaming powdered detergent, catalog number 2204 for the 4 lb box size. For a liquid detergent, use Solujet phosphate free low foaming liquid detergent, catalog number 2101 for the 1 gallon size.

Best Detergent for Polyamides

As you likely know, the Ixef® PARA is part of polyamide family and, as such, has an inherent chemical resistance. While Ixef® compounds display a good resistance to chemical reagents, the amide function in the resin matrix makes them sensitive to certain chemicals. Therefore, we like to recommend….

Monitoring Bath Life Extension in Medical Device Cleaning

Q. What is the best way to monitor for bath life extension?
A.To avoid potential for cross contamination, only freshly made up cleaning solutions should be used for the highest levels of critical cleaning. In general, a pH change of 1 unit towards neutral indicates an exhausted cleaning solution. Bath life can be extended. Learn How.

Brix vs. Conductivity: Measuring Ultrasonic Bath Concentration

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.
