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.
Detergent Bottle Reuse and Recycle?
Q. Can we send back empty Alcotabs jars for re-use?
A. Alcotabs® Tablet Pipet Detergent is indeed a great product and ideal for siphon pipette washers and similar applications where an effervescing detergent is required. We very much echo your sentiment for reusing wherever possible. After all, we live and breathe effective, critical cleaning!
What is Critical Cleaning?
Q: What precisely is critical cleaning? How does it differ from “regular” cleaning? A: It refers to a very specific type of cleaning. It is where the cleaning itself impacts the value of the finished output from whatever residue/contaminant is being cleaned.
Cleaning pH Probes & Dissolved Oxygen Probes
Q. Which Alconox Inc. brand cleaner is well suited for cleaning pH and dissolved oxygen probes?
A. Dissolved oxygen and pH probes used in fermentation vessels can get buildup from the fermentation media that degrades the probe performance and increases the likelihood of batch to batch contamination. Even CIP systems cannot always reliably clean the port crevices and o-rings.
How Does Tergazyme Enzyme Detergent Work?
Q: You recently sent a sample of Tergazyme detergent for a tough biologic cleaning challenge and it worked better than anything we had previously tried. I realize this must be due to the enzyme component. What information can you provide me on how enzyme detergents work, so I can share it with our decision makers / executives who want to better understand why this detergent got such different results?
