Dilution Precision in Concentration Measurements

Q. Do I determine detergent dilution by weight or by volume or both?

A. In a laboratory setting, the most common method is to either make a weight/weight dilution (10-20 g Alconox detergent in 990 g of water), or a weight/volume dilution (10-20 g Alconox in 990 mL of water) for 1-2% solutions.  In manufacturing situations, often directions are written volume/volume or volume/weight.

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.

Detonox 1 gallon

What is Detonox detergent?

Q: You recently recommended Detonox detergent for a tough cleaning challenge we had. You rushed a sample over and it worked fantastically. I have review your technical bulletin, but is there anything else you can tell me about it? Is it better than Alconox and Liquinox? It seems great.

A: Thank you for the feedback and question…..

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.
