Reagent Bottle(Screw Neck DIN/ISO)

A Reagent Bottle (Screw Neck DIN/ISO) is a standardized laboratory container used for safe storage, mixing, and transport of chemical reagents, solutions, and biological media. Designed according to DIN (Deutsches Institut für Normung) and ISO (International Organization for Standardization) specifications—typically DIN 168 / ISO 4796—these bottles ensure international compatibility and consistent quality. They are generally made from borosilicate glass (e.g., type 3.3) for chemical durability and thermal shock resistance, or high-quality laboratory-grade plastics (e.g., HDPE or PP) for lightweight and unbreakable use. The screw neck features standardized GL threads (commonly GL32, GL45, GL80), ensuring secure sealing with compatible screw caps, septum adapters, or tamper-evident closures. These bottles often include graduated volume markings, wide mouths for easy pouring, and autoclavable caps and pouring rings for sterile environments.
