Specifications
The VWR 10-425 Screw-Thread Vials VWC4010-60BLK Polypropylene Caps With Septa are engineered with precision in mind. They are constructed from high-quality borosilicate glass, available in both clear and amber variations for light-sensitive samples. The clear vials are made from 33 expansion borosilicate glass, known for its excellent thermal and chemical resistance. For samples requiring protection from UV light, the 51A amber borosilicate glass is the ideal choice.
These vials feature a 10-425 screw thread, a common and versatile standard in laboratory settings. This thread type ensures compatibility with a wide range of autosampler and manual cap systems. The wide opening is a crucial design element, facilitating easy filling and dispensing of samples, and minimizing the risk of cross-contamination.
Each vial has a maximum fill volume of 1.8mL. This capacity is well-suited for many chromatographic analyses, such as HPLC and GC, where sample volumes are typically small. The accompanying caps are made of durable black polypropylene, a material chosen for its chemical inertness and resilience. Crucially, these caps come with pre-attached septa, simplifying the preparation process and ensuring a consistent seal every time.
Performance & Functionality
In terms of pure functionality, the VWR 10-425 Screw-Thread Vials VWC4010-60BLK Polypropylene Caps With Septa perform their intended task with exemplary reliability.
