Measuring Surface Tension without Tensiometer?

29 August 2018

Q. Is there any way to "eyeball" surface tension to see if it's dropping when roughly measuring concentration or bath life?   A. To numerically measure surface tension, you need a tensiometer and this is the recommended method. Tensiometers come in many varieties including...

Using High Foam Detergent in an Automated Ultrasonic Cleaning Line

20 August 2018

Q. Can we use high-foaming detergents in an automated cleaning line? A. Yes, but using a high-foam detergent requires a rinse chamber that allows foam to rinse off and drain easily and completely. If the automated line uses initial spray rinsing right after the wash tank

Best Detergent for Polyamides

14 August 2018

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....

Surfactant 101 – What are Surfactant Systems?

06 August 2018

Q. In your email you mentioned that Solujet and Citrajet have more sophisticated surfactant systems than a competitor's low foaming washer detergent - could you explain a little bit more what 'surfactant systems' are? A. Absolutely! Surfactants, or Surface Active Agents, are compounds that lower surface tension between particles, such as oil and water. In the oil and water example, a surfactant compound will contain hydrophilic and lipophilic molecules...

How to Clean Laboratory Glassware

12 July 2018

Clean laboratory glassware is essential in all laboratories. No scientist, engineer, laboratory technician, or analyst has time to fail an experiment because of contaminated glassware.   Good, well-built, precision detergents (like the Alconox, Inc. portfolio of course) can make up for quite of bit incomplete, inefficient or incorrect glassware cleaning techniques.

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.
