The ISOLAB Hexagonal Stopper NS 34/35 is meticulously crafted from high-quality borosilicate glass 3.3, renowned for its exceptional resistance to heat and chemical corrosion. This stopper adheres to the stringent DIN 12252 standards, ensuring top-tier performance in laboratory settings. The lower closed end features a "drip-tip" design, facilitating the return of adhered liquids back into the flask, thereby minimizing sample loss. Its hexagonal flat head design prevents rolling on surfaces and allows the stopper to stand upright, reducing contamination risks.
Key Features:
This stopper is an indispensable accessory for laboratories seeking reliable and high-quality sealing solutions for their glassware.
