screw cap

2ml screw cap borosilicate glass vial with closure is a type of laboratory container commonly used for the storage, transport, and handling of liquid or solid samples. It consists of a borosilicate glass vial and a screw cap closure that provides a secure seal. When using screw cap borosilicate glass vials with closures, it is important to handle them carefully to avoid breakage or damage. Proper labeling and documentation should be applied to ensure accurate sample identification and traceability.

2ml UPLC (Ultra-Performance Liquid Chromatography) is a high-pressure liquid chromatography technique used for separating and analyzing chemical compounds. When working with UPLC, it’s important to choose appropriate vials and caps to ensure sample integrity and compatibility with the system.
