Flashcards

Erlenmeyer Flask

A conical-shaped container used for holding and mixing liquids, especially during reactions where splattering might occur. It's not ideal for precise volume measurements.

Beaker

A general-purpose container for stirring, mixing, and heating liquids. While versatile, it's less accurate for measuring volumes than a graduated cylinder.

Graduated Cylinder

A cylindrical container used for measuring liquid volumes with moderate accuracy. It offers more precision than a beaker.

Disposable Pipette

A plastic tool with a bulb used to measure or transfer small quantities of liquid, typically a single drop at a time. It's often disposable and sterile for specific applications.
