Dose and Dab: New Absorber Pen for Diiodomethane
Oct 04 2021
What is the use of Diiodomethane in contact angle measurement?
Diiodomethane, an organoiodine compound, is a standard liquid for contact angle measurements to determine surface free energy. The substance is used, for example, in the quality assurance of activated materials prior to bonding or coating. The otherwise rarely used chemical is used as a nonpolar liquid in combination with polar water and is particularly suitable for this purpose because it forms quite high, easily measurable contact angles and is inert to most materials. It is easy to handle if safety regulations are observed, but it must be disposed of properly. This step is much safer and easier with an Absorber Pen than, for example, with a collection of paper towels or cotton swabs.
New Absorber Pen rapidly removes drops of diiodomethane
Available exclusively from Krüss, the new Absorber Pen for diiodomethane quickly removes drops that have been dosed for contact angle measurements from the sample, simplifying safe handling of the liquid. With the absorbent material inside, the pen holds at least 1000 μL and can be transported and stored safely and odour-free throughout its useful life.
