Study Notes

Laboratory Equipment Overview

Beaker: A glass container for mixing, heating, and stirring liquids. Features a flat bottom and small spout.
Bunsen Burner: A gas burner producing an open flame, used for heating, sterilization, and combustion.
Clamp: Holds round glassware like beakers or flasks securely during experiments.

Heating Equipment

Clay Triangle: Supports crucibles on a ring stand while heating, ensuring stable heating.
Florence Flask: Round body and long neck; used for uniform heating, boiling, and swirling liquids.
Wire Gauze: Metal mesh sheet that sits on a ring stand to support glassware during heating processes.

Handling & Transfer Tools

Crucible Tongs: Scissor-like tool for grasping hot laboratory glassware safely.
Dropper Pipet: Measures and transfers small liquid quantities using milliliters (mL) or microliters (μL).
Pipet Bulb: Rubber bulb used as a vacuum to fill pipettes and control liquid flow.

Measuring Equipment

Electronic Balance: Provides accurate weight measurements for various substances.
Graduated Cylinder: A tall, narrow container for measuring liquid volumes accurately.
Volumetric Pipet: For precise liquid measurements, essential for creating solutions.

Storage & Cleaning

Erlenmeyer Flask: Storage and mixing container with a conical shape; minimizes evaporation.
