Introduction
In modern laboratories, accuracy, safety, and efficiency are non-negotiable. Whether you are working in a pharmaceutical lab, research facility, educational institute, or chemical industry, handling liquids precisely is critical. One essential instrument that simplifies liquid handling is the Bottle Top Dispenser.
What is a Bottle Top Dispenser?
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:
- The dispenser is fixed on the reagent bottle.
- When the piston is pulled up, liquid is drawn into the cylinder.
- When pressed down, the liquid is dispensed in a controlled volume.
- Volume can be adjusted using a knob or dial.
This system ensures accurate and reproducible liquid dispensing.
