Q: Many of your Tergazyme related TechNotes and recommendations include warm temperatures. Warm temperatures can still denature some hormones and proteins thus causing cleaning problems. I would probably start with a cool (room temp or cooler) rinse (water). Then move to the 1-2% cleaning solution in warmer temperatures. Agreed? A: Thanks for reaching … [Read more...] about Advanced Cleaning Mechanisms: Cold or Warm for Proteins?
Q. We run our caustic cleaning at pH 10-10.5. However, the specifications say the nominal pH of a 1% Tergazyme solution is 9.5 Are we compromising cleaning proteins / enzyme performance by using the higher pH and running as part of a caustic cycle? Can we run it at 110F or should we be lower? A. Yes, the enzymes in TergazymeⓇ Enzyme Active Powdered Detergent will perform … [Read more...] about Cleaning Proteins: pH and Temperature
Q. How do I clean liver residues on glassware wells? A. Cleaning glassware wells with liver residues, rich in proteins that can cross-link, can be very difficult. To clean liver residues, we recommend you soak the glassware wells in a warm (110-130 deg F/ ~40 - 55 deg C maximum ) 1% Tergazyme™ Enzyme-Active Powdered Detergent solution (10 g/L or 1.25 oz/gal). Rinse … [Read more...] about Cleaning liver residue off of glassware wells
