Medical Device Cleaning – Rinsing Parts
Q. I would like to know if our rinsing process (Ultrasonic Cleaning with Sterile distilled water for 10 minutes) is appropriate for rinse off. The parts we are cleaning are silicone orings.
A. Thanks for your question about the sufficiency of a 10 min. distilled water rinse in ultrasonics for cleaning medical device related silicon o-rings. Distilled water is generally fine for rinsing. The best rinse is a….
Do Enzymatic Detergents Disinfect?
Q. We have been using Tergazyme to clean lenses and cuvettes for our light scattering equipment and it works flawlessly! My question is: Does Tergazyme enzyme detergent have any disinfection properties, like killing of bacteria such as E. coli, or viruses?
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.
