Laboratory Equipment Flashcards

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.
• Evaporating Dish: Glassware for evaporating solutions, resulting in concentrated liquids or crystal precipitates.
• Test Tube Brush: Cleans test tubes and narrow laboratory glassware effectively.

Safety Gear

• Safety Goggles: Protective eyewear to shield the eyes from chemical splashes or substances.
• Test Tube Holder: Keeps hot test tubes secure and safe to handle without direct contact.

Miscellaneous Tools

• Scoopula: A spatula-like utensil for transferring dry chemicals; useful for weighing small amounts.
• Stirring Rod: Thick glass rod used for mixing chemical solutions thoroughly.
• Watch Glass: Curved glass dish used for evaporation, weighing solids, or covering flasks.

Instrumentation & Precision

• Thermometer: Measures temperatures of solids, liquids, and gases in Celsius, Fahrenheit, or Kelvin.
• Triangular File: Used for scratching glass tubing before breaking or grinding chemicals into powder.
• Rubber Stopper: Seals glassware to prevent spillage of contents, ensuring safety in experiments.
