Graduated Pipettes: 

  • Graduated pipettes, as you may guess from the name, have markings along the stem. These markings represent the volume of liquid the pipette can hold at any point.
  • They are versatile and can measure various volumes, making them a favorite among scientists and students alike.
  • Graduated pipettes come in two types, TD (to deliver) and TC (to contain). ‘TD’ pipettes are designed to deliver the exact volume indicated on the markings, while ‘TC’ pipettes contain the specified volume but do not necessarily deliver the entire amount due to remaining droplets.

Glass Bulb Pipettes: 

  • On the other hand, glass bulb pipettes (or volumetric pipettes) have only one marking that denotes a fixed volume. The bulb in the middle holds this specific volume of liquid when fully filled.
  • They’re designed for precision, providing a highly accurate measurement of a specific volume. This accuracy is especially vital in analytical chemistry experiments.
  • The only drawback is, they can’t measure varying volumes like their graduated counterparts.

So when you’re deciding between a graduated pipette and a glass bulb pipette, consider the level of accuracy you need and the variability of volumes you’ll be dealing with. In the end, it all comes down to the task at hand!

How do you clean a glass bulb pipette?

Let’s dive right in! Cleaning a glass bulb pipette isn’t as complicated as you might think. In fact, it’s pretty straightforward and can be broken down into a few easy steps. 

What you’ll need:
