Some compounds adsorb to borosilicate glass due to hydroxyl groups / silanols on the glass surface and others adsorb due to hydrophobic interaction with the glass itself.

Deactivated (surface treated) RSA-Pro X™ vials offer the best glass options for you since the surface treatment is more complete than any other glass vial available and the surface is non stick, hydrophobic and hydrolytically stable even when heated and cooled.

if you can use plastic vials, your best option is most likely using the 300ul LCMS Poly Vials or our 700ul LCMS Poly Vials.
