bottle top dispenser

Have you ever heard of a bottle top dispenser? Basically, a bottle top dispenser is an instrument that is used to accurately and safely dispense precise volumes of chemicals, reagents, solvents, and oils from containers.

A bottle top dispenser is an important tool in preventing spills, measurement inaccuracies, and potential lab accidents during manual dispensing processes. This apparatus enables controlled delivery of a predetermined liquid volume, typically ranging from 1 ml to 100 ml, directly from a source bottle to a receiving container. 

Components of a Bottle Dispenser

Piston Mechanism

A bottle dispenser mainly consists of a piston, a seal, and a spring. When you turn the adjustment knob, it moves the piston inside the dispenser barrel. Pressing down the piston creates a vacuum or pressure, allowing the liquid to be drawn into or dispensed from the dispenser, depending on the knob’s direction.

Adjustment Knob

With the help of bottle top dispensers, you can choose how much liquid you want to dispense. By turning the knob, you can control the piston, which in turn determines the volume of liquid released. This allows you to dispense liquids with high accuracy and precision during your experiments.

Dispensing Nozzle

It regulates liquid flow for precise dispensing and measurement. The valve mechanism ensures consistent delivery, prevents leaks, and supports compatibility with different bottles, making it a vital tool provided by a reliable laboratory equipment supplier for accurate laboratory operations. 

Bottle Adapters

Last but not the least is the bottle adapters, which enable bottle-top dispensers to securely attach to different sizes of reagent bottles. Basically, they act as a bridge between the dispenser and the bottle, ensuring a tight and leak-proof fit.

Types of Bottle Dispensers

Fixed Volume Dispensers

As the name suggests, fixed volume dispensers are designed to dispense a specific, pre-set volume of liquid with each operation. Fixed volume dispensers are perfect for applications where the same volume of liquid needs to be dispensed frequently and with precision. They usually lack an adjustment knob and are pre-calibrated to dispense a single, fixed volume.

Adjustable Volume Dispenser

The next type is an adjustable volume dispenser that allows you to manually set and adjust the volume to be dispensed using a knob or dial mechanism. This versatility makes the dispenser ideal for various experiments requiring accurate and efficient liquid handling across different volumes.

Advantages of Using a Bottle Top Dispenser

  • Ergonomic Design: They are designed to ensure comfortable handling during operation, reducing hand fatigue and improving user experience. 
  • Time-Saving: Bottle top dispensers simplify liquid dispensing, saving time and effort compared to manual pipetting or alternative methods. 
  • Versatility: They can handle various types of liquids, including acids, bases, and organic solvents, making them suitable for diverse laboratory applications. 

Conclusion

In the end, bottle top dispensers are a crucial piece of apparatus in a modern-day laboratory as they ensure safe, precise, and efficient liquid handling.
