Bottle top dispensers are essential tools in laboratories that handle liquid reagents on a routine basis. They attach directly to the bottle opening, enabling precise, repeatable, and safe aspiration and dispensing of fixed volumes of liquid without the need for intermediate containers. Using a bottle top dispenser significantly reduces operational risks, saves working time, and ensures high accuracy in volume measurement compared to manual pouring or pipetting directly from the bottle.
A bottle top dispenser operates based on a piston and valve mechanism that allows controlled aspiration of liquid from the bottle (or from an external container connected by a suction tube) into a measuring cylinder, and precise dispensing of the set volume. The user sets the desired volume using a scale or digital display on the device, and the operating mechanism (typically by pressing a plunger) repeatedly draws and dispenses the precise volume. Many models include integrated air purging and recirculation mechanisms that ensure unused liquid returns to the source bottle, preventing waste and risks.
The accuracy benefits of these dispensers stem from the precise mechanical control over the piston movement and the prevention of human errors common in manual pouring. Additionally, they significantly reduce exposure to reagent vapors, especially when working with volatile solvents, concentrated acids, or strong bases, thereby contributing to user and environmental safety in the laboratory. Advanced models offer self-calibration options, memory for frequently used volumes, and other features that streamline routine work.
Bottle top dispensers are a routine and essential tool in a wide range of laboratory disciplines:
They allow for efficient and relatively risk-free handling of many liquids and prevent measurement errors resulting from uncontrolled large-volume pipetting directly from the original bottle. Their ease of use makes them suitable for a wide range of users and applications.
