Dishwasher Rinse Aids Interfere w/ Wine Tasting
Rinse aids work by placing rinse aid residue on the surface of glasses and smallware being cleaned. The residue in the rinse aids left on surfaces are hydrophobic molecules, which stick to the surface to repel water. Less water on the surface, means less water that needs dried, and that leaves less water available to make streaks and water spots. But there’s a problem…
Cleaning Protein in Pharmaceutical and Biotech Manufacturing
Q. How do you remove protein out of pipes, centrifuges and tanks in a CIP environment with water temperatures averaging 20C?
A. In a cooler temperature environment, consider adding an enzymatic cleaner to your alkaline/acidic CIP routine. A product like Tergazyme® Enzyme-Active Powdered Detergent, which contains both protease and surfactants, is not only efficient at removing the biofilm, but will also slow down the formation of biofilm and allow the regular cleaning cycle to clean effectively for more cycles.
Do Your Cleaners Have Animal Origins?
Q. Does Alconox or any other recommended detergent have animal origins?

Labware Cleaning: Pre-soaking Pipettes
Q. Why is it important to pre-soak pipettes in 1% Alconox or Liquinox before washing in pipette siphon washer with Alcotabs?
A. The most common problem in pipette cleaning is residues that dry on after use and prior to cleaning. This problem is attributed to the failure to pre-soak the pipettes immediately after use. Our technical experts at Alconox recommend placing soiled pipettes in 1% Alconox or Liquinox solution immediately. Learn More.
Cleaning Carbon Deposit Swirls On Alumina Parts
Q. Our parts, made of 99.5% alumina, have carbon deposits that show up after our brazing process. We do not use a flux for our ceramic parts; we high-temp fire a moly/manganese painted paste onto the ceramic. The part is then sent out for nickel plating to prevent corrosion of the moly manganese metallization areas. The next step is our brazing.
We are not seeing any spots on the parts before brazing, but as we continue through 5 brazing cycles and braze in a hydrogen/Nitrogen furnace with the cusil braze rings, we see black spots forming that show up as high-carbon deposits with the SEM data…
