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.

Pre-soak for Tough Residues in Medical Device Cleaning & Reprocessing

Q. We reprocess single use medical devices and we are having trouble getting organic and biological residue out of crevices. It is requiring cleaning for a much longer time than we can support in our processes. We’ve started to do pre-soaking as we read that this would help, but we’re a little concerned we are not doing that optimally either. Can you make recommendations?
