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.

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…
