What is a Bottle Top Dispenser?

A bottle top dispenser is a laboratory device mounted directly on top of a reagent bottle to dispense liquids in controlled volumes. It is widely used for acids, bases, solvents, and other chemicals.

Unlike traditional measuring methods, this device ensures:

• High precision
• Repeatable dispensing
• Safe chemical handling

Working Principle of Bottle Top Dispenser

The working principle is based on a piston-cylinder mechanism.

How it works:

1. The dispenser is fixed on the reagent bottle.
2. When the piston is pulled up, liquid is drawn into the cylinder.
3. When pressed down, the liquid is dispensed in a controlled volume.
4. Volume can be adjusted using a knob or dial.

This system ensures accurate and reproducible liquid dispensing.
