Cleaning Polycarbonate with Alconox

21 August 2014

Q. We use 4-way stopcocks made of radiation-grade Polycarbonate and HDPE that are not normally cleaned with Alconox. They were accidentally put through the Alconox cleaning process. Stopcocks feel a little stiff, but otherwise appear ok. Would like to know if there are any concerns for this material/corrosion or other incompatibility known with Alconox? A. Stressed polycarbonate is not compatible with low surface tension solutions and heat. Polycarbonate that is unstressed will not have this problem and can be cleaned with Alconox.

Stripping NiCr-AG-NiCr Coating

18 August 2014

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.

Filter Cleaning for Beer Flavor and Clarity

15 August 2014

In breweries, filters are used to control and improve flavor and clarity of beer. One Lab technician improved the flavor and clarity of beer by better filter cleaning. Filtering removes yeast, tannins and some large proteins from the beer that contribute both to off flavors and haze. These residues clog the filters.

Alconox Detergent Measuring Scoops

14 August 2014

Q. I received Alconox samples a while back, and in the letter accompanying the samples, it is mentioned in a P.S. that you will send us a free detergent measuring spoon to thank us for sending the test report form back to you. I would like to know if you have measuring spoons to contain 10g of Alconox, for we measure in metric values, therefore using the ratio 10g per liter instead of gallons. For now, we would have to weight the quatity of soap to add to the water, which is less user-friendly.

Cleaning Glassware Exposed to Sea Water

13 August 2014

Q. What is the proper way to clean lab glassware that has been exposed to sea water? A. Sea water contains a large and variable quantity of salts, biological and organic residues. Lab glassware needs to be free of any of these residues to avoid interference in research involving sea water. Sea water would not particularly present challenges beyond the normal array of residues that lab glassware sees in the wide variety of types of lab glassware that Alconox, Inc. laboratory detergents are used to clean. A standard cleaning protocol will work fine.

Removing Protein from Cell Culture Containers

11 August 2014

Q. We need to remove protein from cell culture containers. A. To clean cell culture containers and remove protein, use a freshly made 1% Tergazyme solution (1.25 oz/gal or 10 g/L) with warm water (less than 130 deg F or less than 55 deg C). After soaking, rinse thoroughly with water. Depending on the amount of protein build up, some light scrubbing or longer soaking may be required.
