This 100-pack of black vial caps and PTFE septa has been strictly QC tested for cleanliness properties and dimensional tolerances to ensure proper application. At Waters, we believe it’s of the utmost importance that you receive liquid chromatography and mass spectrometry products that have undergone thorough testing before being shipped to a lab. If a component of sample preparation isn’t working properly, that can result in the scientists to have to restart their preparation protocols. That’s another reason why we think having the cleanest products from us is incredibly important.

Do you need to stock up on sample vials as well?
If you’re working with compounds that may deteriorate when subjected to UV rays, make sure to use the LCGC Certified Amber Glass Screw Neck Vial. This vial prevents UV rays from contaminating your sample, plus it’s tested for cleanliness by HPLC and held to the tightest dimensional tolerances in the industry.
