Q. Which Alconox Inc. brand cleaner is well suited for cleaning pH and dissolved oxygen probes?
A. Depends on the application and use. For laboratory based usage with reagents and solvents and the like, general cleaners such as Alconox® Powdered Precision Cleaner and Liquinox® Critical Cleaning Liquid Detergent will work great. 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 may not always reliably clean the port crevices and o-rings. This is a particular problem with proteins found in pharmaceutical, biotech, or cheese and brewery manufacturing. They can be adherent and quite a challenge to remove.
- Use a 1-2% Tergazyme® Enzyme-Active Powdered Detergent solution that does not exceed 130F (55C), preferably around 120F (50C).
- Clean manually with a small brush.
- Rinse thoroughly with water of suitable purity for your industry.
O-Rings and other removable parts can be soaked in a warm Tergazyme solution for 20 minutes prior to final brushing and rinsing.
The Tergazyme solution should not exceed 130F (55C) to avoid enzyme degradation and should be used within 8 hours to avoid enzyme auto-catalysis.
Tergazyme detergent is a powerful emulsifier of organic and oily residues, enhanced with proteolytic enzymes for excellent biologic and proteinaceous residue removal. Our fun Tergazyme video discuss this in further detail…
