Laboratory sample container COT

Overview
Measuring the total organic carbon (TOC) content in pure water involves a risk of laboratory contamination that can significantly affect results. Certified Quality (CQ) vials are produced and cleaned under tightly controlled processes to minimize leaching of organic impurities, making them suitable for pure water and low‑concentration TOC samples.

Features — Reliability

• CQ vials are supplied with a product certificate confirming organic impurity leaching is less than 10 µg C/L.
• Vials are pre‑cleaned to prevent accidental contamination during in‑lab cleaning, drying, or storage.
• Each vial is sealed with a cap and septum and packed in a protective plastic box to inhibit dust and external contaminants.

Features — Efficiency

• Pre‑cleaned status allows immediate use after opening the box, eliminating in‑lab cleaning and drying steps.
• Reduces handling and dedicated storage space, streamlining sample preparation and improving laboratory workflow.
