Q. What is the best way to monitor for bath life extension?
A.To avoid potential for cross contamination, only freshly made up cleaning solutions should be used for the highest levels of critical cleaning. In general, a pH change of 1 unit towards neutral indicates an exhausted cleaning solution. Bath life can be extended. Learn How.

Q. How can Alconox detergents assist with our movement to continuous bioprocessing? A: Continuous bioprocessing is an exciting newcomer to the biotech realm. It has been used in industries such as food and chemicals for some time, effectively so. With improvements in cell culture perfusion, and the many forms of disposable technologies on the market, footprints can be reduced making continuous processing for biotech products a reality for many applications.

Q. We are moving from LD50 data to ADE (PDE) limits based on HBELs. This is allowing us to eliminate disposables for low-risk products.  How do I know which can be manually cleaned and which needs to be in a washer? Can manual cleaning be validated?

A. Many pharma and biotech companies have been moving to Health-Based Exposure Limits (HBELs) meaning Acceptable Daily Exposure (ADE) or Permitted Daily Exposure (PDE) limits as detergent residue limits.    

Your detergents have corresponding biocompatibility data. Our medical devices must be pyrogen and endotoxin free. Someone mentioned that biocompatibility tested detergents, like yours, will be free of organic residues like endotoxins and pyrogens. Is this true?

Q: Can you tell me if Liquinox can clean/remove pharmaceutical probiotics? We use this product to clean our packaging lines. We have a customer who is looking to have us package their probiotic product.

A: Liquinox® Critical Cleaning Liquid Detergent is an excellent emulsifier of organic and oily residues. It will do the job. Best practice, however, would be to incorporate a powerful emulsifier of organic and oily residues, along with enhanced protein removal.
