The Syringe-Based Drop Dispenser is an inexpensive alternative to a burette. Students control the drop rate with the 2 stopcocks and read the volume delivered with the graduated markings on the syringe body.
Features: Robust, Inexpensive, Lightweight
This Drop Dispenser delivers up to 60 mL of solution with a pressure head change of 5 cm—about 16% of the 32 cm pressure head change observed with delivery of 30 mL from a burette. One stopcock controls the drop rate while the other is used to start and stop the flow of liquid.
