Dilution Precision in Concentration Measurements

Q. Do I determine detergent dilution by weight or by volume or both?

A. In a laboratory setting, the most common method is to either make a weight/weight dilution (10-20 g Alconox detergent in 990 g of water), or a weight/volume dilution (10-20 g Alconox in 990 mL of water) for 1-2% solutions.  In manufacturing situations, often directions are written volume/volume or volume/weight.

How To Clean Carbide

Q:I was wondering if you have a product that I can use in an ultrasonic cleaner to clean tungsten carbide that would not leach out cobalt? That also can be disposed of down a drain?

A: Tungsten carbide (WC) cleaning comes with some inherent issues, and the cleaning cycle that accompanies it will depend entirely on the feed stock (components to be cleaned) that the process comes from. This is where Alconox, Inc., as the critical cleaning experts, excel from our experience and vast pool of applications to draw upon.

Cleaning Pipettes in the Laboratory

Q. What are some best practices for lab cleaning of pipettes. We’re having trouble in our lab removing dried on residues.
A. The principal concern for any scientist or technician working in the laboratory is that glassware, like pipettes, be free of interfering residues after they are cleaned. Unseen residues can wreak havoc on analytical results by inhibiting culture growth, causing cross contamination, non-reproducible results and more.

Bleach with Detergents for Disinfection?

Adding bleach to Alconox and Liquinox detergents can be done to enhance the disinfecting and oxidizing properties of these cleaners. Adding oxidizing does bring one more cleaning mechanism to the cleaning process which can be helpful if you are trying to clean dyes, pigments, heavy burned on organic residues and other residues that are labile to oxidation. You can get some disinfection, but as we will explain, you need to clean a surface first before you disinfect.

Ultrasonic Cleaning: Detergent Bath Life

Q: We manufacture medical devices. Can we use our Alconox or Citranox bath solution more than once? How do we know that we need to change the solution?

A: For the highest level of cleanliness, you only use a solution once. In general, in a medical device manufacturing and cleaning operation, a detergent bath will typically easily last for 8 hours.

For example, you can make up a fresh Alconox® or Citranox® solution once a day and then verify that the pH has not changed more …
