Lowering the pH of Tergazyme
Q. Can you lower the pH of Tergazyme using Citric acid or vinegar?
A. Yes. To adjust the pH of a 1% Tergazyme solution from pH 9.5 to about pH 8.5 add 0.1 grams of 99% anhydrous citric acid for each 5 grams of Tergazyme.
Stopcock Grease Removal with Alconox
Q. Silicon oil based stopcock grease used to assure that ground glass joints and stopcocks did not freeze got onto glassware and could not be removed by standard cleaners.
A. Silicon the silicon grease contaminated glassware in very hot (170 deg F- 75 deg C) double strength 2% Alconox …
Medical Device Cleaning – Automated Machine Detergent
Q. We are looking to use Liquinox in an automated cleaning machine. The cleaner would be agitated ultrasonically and pumped to/from the storage tank by magnetic drive pumps. We are worried that the Liquinox will foam during the transfer by pump. Is this a valid concern? If so, is there an alternative cleaner that we could use in place of the Liquinox?

Stripping NiCr-AG-NiCr Coating
Q. To strip NiCr-Ag-NiCr coating, I was preparing a solution @4% of Cerium Ammonium Nitrate (C.A.N.)and I added Citrajet @1% to be used as a wetting agent (surface inclined). The addition of Citrajet neutralized completely the effect of the C.A.N; which did not attack the NiCr layers. Can you give me some explanation and which Alconox product I have to use as wetting agent.
A. CAN is a very strong oxidizing agent. Organic functional groups with double bonds, alcohols, benzene rings and ethers are likely to be oxidized by CAN, thereby “neutralizing,” or depleting it, thereby rendering it less effective for stripping coatings. Most wetting agents have organic functional groups that will be oxidized by CAN, including Citrajet.
