They can be used immediately after opening the box. Cleaning and drying operations are no longer needed. It also eliminates the need to carefully avoid contamination during storage. That means significantly less time and space are required for operations.   Measurement Method A large thoroughly-cleaned glass bottle was filled with ultrapure water. That water was dispensed from the bottle into a vial and the TOC level was measured in both the bottle and vial. Using the bottle water measurement results as blank data, the quantity leached from the vial was determined by subtracting the blank measurement results from the vial measurement results. Leaching was evaluated in that way a total of six times, including three times for vials (reused vials) cleaned using a laboratory equipment cleaning machine and three times using CQ pre-cleaned vials. CQ vial were significantly more effective at inhibiting leaching than the vials cleaned in the cleaning machine. Therefore, the use of CQ vial should be considered not only by customers measuring pure water, but also by customers that want to avoid contamination during vial cleaning, drying, and storage, and customers looking to save the time and space required for cleaning, drying, and storing vials.
