TOC Sample Bottle

Sample vials carry a central role in the drug testing process. However, many pharmaceutical companies tend to focus only on price when purchasing sample vials and neglect the impact of sample vial quality on test results. The quality of sample bottles is not only related to the accuracy of the experiment, but also directly affects the recovery and reproducibility of TOC (Total Organic Carbon) testing in the pharmaceutical industry.
The quality of the sample vials is crucial to ensure the accuracy and reliability of the test results. Our brand, Brilliance Sun, understands this and is committed to meeting the high standards of pharmaceutical TOC testing through its well-designed sample bottles. Below is a detailed explanation of how Brilliance has fine-tuned the design of the three key components of the vial – cap, gasket and body – to meet the industry’s stringent standards.

Bottle Caps: The Perfect Combination of Sealing and Dust Protection
To prevent contamination due to laboratory errors, Brilliance Yang TOC sample bottles and caps are strictly sized for analyzing volatile organic compounds (VOA), with a soft sealing polytetrafluoroethylene (PTFE)/silicone gel spacer, and a dust cap that stays closed when filling the bottle with water and removes when placing the sample, to avoid potential contamination due to laboratory errors.
A polyethylene dust cap is pre-installed on each cap to protect the spacer from particulate buildup prior to analysis, and the tightness of the cap is precisely controlled to ensure a tight seal while avoiding cap damage or deformation due to over-tightening.

Bottle Gasket: Double Guarantee of Corrosion Resistance and Non-stickiness
Brilliance Yang TOC sample bottle gaskets are produced using imported Teflon and silicone raw materials. The Teflon material has excellent resistance to acids, alkalis and organic solvents, and its non-adhesion ensures that the components of the bottle gasket will not penetrate into the sample during TOC testing. Silicone material with its unique physicochemical properties, such as electrical insulation, temperature resistance and waterproof effect, as well as soft hardness, to ensure that the autosampler needle puncture does not leak, no residual sample accumulation.
