What is the most accurate glassware?

Burettes are one of the most accurate glassware for measuring volumes. They fall under the category of volumetric glassware. They are cylindrical in nature like the graduated cylinders with their calibrations printed on the side. The only difference is that their designs are narrower.

What is a pipette?

Pipettes. Pipettes are a kind of volumetric glassware that is designed as very long and narrow glass tubes. It has a little rubber bulb at the center, a narrow tip and a hash mark that tells you when it is full. The bulb is used to create a vacuum of sorts that helps to suck air and then draw the liquid into the device.

What is a graduated cylinder?

Hence, they’re used solely as containers. 2. Graduated Cylinders. Graduated cylinders are tall narrow vessels. Like the name suggests this type of glassware contains proper markings that are generally present on the sides. In addition to that, it has a glass bottom that functions as a spout to pour the liquid out.

Is glassware accurate?
