Merck: Low Adsorption (LA) – Vials Neutral pH

Profile: Enjoy the benefit of maximum sample extraction, without the worry of trace analytes being adsorbed to the surface of our certified Low Adsorption, Center Drain, MRQ30 and QsertVial products.

Features and Benefits:

Maintains sample integrity during storage
Minimizes pH shifts in the sample
Reduces metal contamination in the sample
Compatible with most autosamplers.

Supelco’s new certified low adsorption CD, MRQ30 and QsertVial products now offer the benefit of maximum sample extraction without the worry of trace analytes being adsorbed by the vial surface. These 12 x 32mm vials are manufactured from Type 1 borosilicate glass with a 9mm thread.

The Low Adsorption (LA) – Neutral pH vials are manufactured using a process that decreases the number of hydroxyl groups on the vial’s glass surface, significantly reducing surface activity while improving analytical quantitation and minimizing pH shifts in the sample. This same process also removes unwanted surface metals such as sodium and boron that can contaminate samples and interfere with trace analysis. Unlike other methods used to decrease vial surface activity, the elimination of surface activity in LA vials is integral to the manufacturing process and is not a chemical surface treatment.
