How to Clean Mold Release Agent from HDPE parts?
Q. We are looking for a product that will allow us to clean mold release agent from the surface of molded HDPE parts. A. The best way to reliably remove silicone based mold release agents is to immerse the HDPE parts in very hot (170ºF) 2% Alconox detergent followed by a very hot (170ºF) rinse, ideally both in ultrasonic tanks. After the first very hot rinse, normal ambient temperature rinsing can be done. This can also be done with stiff brushes, but of course protective equipment must be worn.
The theory behind this is that …
Advanced Cleaning: Relationship Between Conductivity, Surface Tension and pH
Q: I am doing a conductivity study using Alconox detergent. I am seeing that the pH and Surface Tension listed on the COA differs between lots. Do you think these variables affect conductivity enough to alter my results?
A: Here’s the short answer… Surface tension does not have any interactive relationship with conductivity; pH has a very small, essentially negligible interaction with conductivity; and concentration and temperature are much bigger causes of change in conductivity.
Replacing Hazardous Acids
Q: What can I use to replace hazardous acids below pH 1 cleaning?
A: Depending on exactly what you are using your acid cleaning to do, we may be able to help you.
Monitoring Stability of Alconox Solution
Q: Is a 1% Alconox solution stable in tap water? How long can 1% Alconox be stored as solution? Is pH measurement the best estimate of stability?. A: lconox® Powdered Precision Cleaner, is stable in tap water (or any purity water- within reason) for….
How to Clean Labware: Don’t Use Grocery Store Detergents
Q. We use grocery store detergents to clean our labware and it recently came to my attention that we may need to switch to a laboratory grade detergent such as Alconox or Liquinox. Why is that necessary?
A. Here are some insights as to why a grocery store detergent is not suitable for use in a lab…
