Dispenser Bottle-Top Dispenser, 2.5-25 mL and ±0.5% Accuracy (CAT#: STEM-BC-3833-ZJF)

The Dispenser 2.5-25 mL is a bottle-mounted instrument for precise medium-volume liquid distribution. It delivers repeatable portions directly from the original reagent container. This design reduces handling steps, reagent loss, and exposure to corrosive liquids. The dispenser is appropriate for common laboratory acids, alkalis, salts, and dilute strong reagents. Its liquid-contact path uses chemically resistant PTFE, FEP, BSG, and PP components. The wetted assembly can be sterilized by steam at 121°C. The modular design permits convenient disassembly for cleaning and maintenance. It supports liquids with temperatures up to 40°C and pressures up to 500 mbar. Supplied adapters allow installation on five different bottle-neck standards.
