DURAN Dropping Funnel Borosilicate 241222409 100 mL
The DURAN Dropping Funnel Borosilicate 241222409 100 mL is built for precise metered addition of liquids to reaction mixtures. Its cylindrical shape with graduation markings allows visual monitoring of volume in the funnel or dispensed volume.
It’s equipped with a standard NS-type stopcock and a key retention device to prevent accidental rotation, ensuring safe and controlled flow.
Manufactured from DURAN borosilicate glass 3.3, the funnel resists chemical attack, tolerates thermal stress, and is autoclavable for reuse.
Ideal for applications in both research and teaching labs, this funnel makes it easier to add reagents dropwise or continuously with precision.
