Bottle-Top Dispenser

A bottle top dispenser is a common lab instrument used to dispense precise amounts of chemicals/ reagents, organic and inorganic solvents, oils, etc. from bottles or other containers. Bottle top dispensers can safely dispense a fixed amount of liquid, directly from a bottle to a receiving container, typically between 1ml and 100 ml. All bottle-top dispensers work on the piston principle, which means that the piston and some other internal parts are in direct contact with the liquid. All bottle-top dispensers work on the piston principle, which means that the piston and some other internal parts are in direct contact with the liquid. Therefore, the chemical compatibility of the instrument must be able to withstand the liquids used in the laboratory.
