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 … [Read more...] about Dilution Precision in Concentration Measurements

Measuring Surface Tension without Tensiometer?
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 Goniometer, Du Noüy Ring, Wilhelmy Plate and Bubble Pressure. Having one of these for measuring surface … [Read more...] about Measuring Surface Tension without Tensiometer?
Utilizing Alconox on Stainless Steel
Q: We currently use Alconox detergent on our manufacturing equipment as well as a glass cleaner in the labs. We are qualifying a piece of equipment and wanted assurance that Alconox detergent can clean different types of Stainless Steel. I downloaded the Tech Bulletin that notes Stainless Steel, but does not give any specifics. Do you have documentation regarding the … [Read more...] about Utilizing Alconox on Stainless Steel
Alconox solution turning brown
Q. The 1% Alconox solution (1 us cup in ~6 gal) is turning brown after a few days of light use. Also, I wanted to know if there is a liquid Alconox I can use to create a replacement liquid with when the tank level drops. I noticed the Alconox powder has a ph of ~9.5 and the Liquinox is 8.5ph, not sure how this would work. A. The Alconox solution turning brown is very … [Read more...] about Alconox solution turning brown
