The Corning Bottle Top Dispenser is a universal solution for dispensing organic and inorganic liquids. The specialized airpurging and closed circuit system ensures no loss of reagent during dispensing, as well as when the device is not in use. The dispenser comes with 4 adapters with different diameters for universal use with multiple bottle sizes. The telescopic suction tube can be adjusted smoothly to different bottle heights. The calibration tool allows easy in-lab calibration with a built-in recalibration mechanism to ensure the highest reproducibility during the dispenser’s long life cycle. Every dispenser is individually tested and delivered with a certificate of performance. Corning Bottle Top Dispensers are suitable for using with a wide range of chemical solutions. The components that come directly in contact with the reagents are made of chemical resistant, robust materials such as platinum, ceramic, PTFE, or borosilicate glass.
