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.
Removing Polishing Compound from Aluminum
Q. What Alconox product is ideal for manual removal of polishing compound from aluminum?
A. For manual cleaning of aluminum use a warm 2% Citranox solution to remove the polishing compound. Citranox will not harm the mirror finish on the aluminum. Rinse thoroughly after washing.
Solujet Inhibited for Cleaning Aluminum
Q. Specifications indicate that “Solujet is inhibited for Aluminum. Corrosion testing is advisable.” What does this mean?
A. Solujet contains sodium metasilicate which acts as a corrosion inhibitor to stop alkaline attack on aluminum. Solujet would not cause alkaline attack on aluminum as long as the bath is not overused and the metasilicate depleted. Learn more.
Cleaning Denatured Proteins
We are looking to clean denatured proteins from our medical device along with baked-on desiccated blood that is not removed completely. Manual scraping removes the residual but is not acceptable. Need a cleaner that will dissolve all bio-matter. Cleaning process is to prepare device for autoclave sterilization.
