Description
Dropping funnel 100 ml with socket NS 14,5/23 and cone NS 14,5/23 is a graduated cylindrical laboratory vessel fitted with a solid glass stopcock of 2,5 mm bore. Made from borosilicate glass 3.3, it incorporates a drain tube with drip tip and precision ground joints for leak-free connections. The clear graduation enables accurate monitoring of liquid volumes during controlled addition in synthetic, preparative, or analytical procedures. Nominal volume reaches 0,1 l, while the stopcock (NS 12,5) provides dependable flow adjustment. This configuration mates readily with standard laboratory glassware trains. Offered by manufacturer Rettberg, the funnel delivers the chemical durability and thermal performance expected from borosilicate 3.3. Its cylindrical profile and reliable stopcock support reproducible dosing in research, process development, and educational laboratories. Net weight is 0,142 kg, allowing straightforward manipulation on the bench whenever measured reagent introduction is required.
