Dispenser Bottle-Top Dispenser, 5-50 mL and ±0.5% Accuracy (CAT#: STEM-BC-3834-ZJF)

The Dispenser 5-50 mL is a large-capacity bottle-top dispenser for controlled reagent transfer. It accurately distributes liquids directly from storage bottles in repeatable portions. The broad volume range is suitable for solution preparation and other higher-volume laboratory procedures. Direct dispensing helps reduce reagent waste and operator contact with corrosive media. The fluid-contact components are made from resistant PTFE, FEP, BSG, and PP materials. These components can be autoclaved at 121°C for sterilization. The instrument can be dismantled easily for cleaning and routine maintenance. It handles liquid densities up to 2.2 g/cm³ and viscosities up to 500 mm²/s. Five included adapters support installation on several common reagent-bottle threads.
