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 it used for? Pipettes are primarily used as media dispensers. That means that they help chemists/experimenters to transfer liquids from one container to another during lab a procedure.
What is the level of accuracy? Highly accurate. Their accuracy is partly dependent on their size which comes in a range of 12 to 24 inches. The graduations on a pipette can measure liquids within a 0.02 ml range.
Which Glassware Should You Use for Accurate Measurements?
On the whole, all the different glassware have a level of accuracy that works in specific cases. So you’ll probably use devices that won’t necessarily be the most accurate glassware for measuring volumes in a certain situation. They key to chemistry experiments is to use high-quality products that are tolerable to the hazardous chemicals in use and provide accurate readings.
