Dispenser Bottle-Top Dispenser, 0.5-5 mL and ±0.5% Accuracy (CAT#: STEM-BC-3831-ZJF)

The Dispenser 0.5-5 mL is a bottle-top dispenser for accurately transferring laboratory liquids directly from reagent bottles. It supports repeatable dispensing while reducing reagent waste. The instrument is suitable for general acids, alkalis, salts, and low-concentration strong acids and bases. Liquid-contact components are made from chemically resistant materials including PTFE, FEP, BSG, and PP. These materials provide chemical inertness, mechanical strength, and corrosion resistance. The wetted components can be steam sterilized at 121°C. The dispenser can be disassembled for convenient cleaning and maintenance. It withstands liquid pressures up to 500 mbar and viscosities up to 500 mm²/s. Five bottle-neck adapters are supplied to support different reagent containers.
