Chemistry Lab Equipment Flashcards

Lab Equipment Overview

• Graduated cylinder measures liquid volumes with moderate accuracy.
• Buret enables precise measurement during titrations, integral for achieving exact chemical reactions.
• Ring stand supports various apparatus for heating, allowing items to be elevated above surfaces.
• Test tubes facilitate small-scale chemical experiments and reactions.

Mixing and Heating Tools

• Glass stirring rod combines or mixes chemical solutions efficiently.
• Rubber policeman acts as a spatula for scraping contents from beakers.
• Utility clamp secures various items in place during experiments.
• Evaporating dish is used for heating liquids until evaporation occurs.

Heating Sources

• Burner provides flame for heating substances and conducting reactions.
• Mortar and pestle crush solids into fine powders for easier dissolution.
• Beaker tongs safely handle hot beakers to prevent burns.

Specialized Heating Tools

• Clay triangle supports crucibles for high-temperature heating.
• Watch glass serves as a lid for evaporating dishes and can hold solids for weighing.
• Erlenmeyer flask is a versatile vessel for heating, storing liquids, and mixing due to its unique shape.

Precision Measurement and Handling

• Volumetric flask accurately measures a specific liquid volume, similar in precision to graduated cylinders.
• Crucible and cover enable heating of small solids at elevated temperatures.
• Crucible tongs specifically designed for handling hot crucibles without direct contact.

Dispensing and Directing Liquids

• Wash bottle dispenses small amounts of distilled water for rinsing or hydration.
• Funnel directs liquids into containers with minimal spillage for precision in pouring.
• Disposable pipets allow for drop-by-drop liquid dispensing; convenient and single-use.

Safety and Maintenance Equipment

• Wire gauze supports items atop a ring stand while also indicating potential heat hazards.
• Scoopula moves small solid amounts efficiently without the risk of contamination.
• Test tube clamp specifically designed for safely handling test tubes during experiments.

General Purpose Tools

• Forceps manage small objects or hazardous materials without direct contact.
• Test tube brush cleans and maintains cleanliness of test tubes for repeated use.
• Well plate accommodates microscale experiments, featuring multiple wells for various reactions.

Marking and Safety Equipment

• Glass marking pencil allows for temporary labeling on glassware, easily erasable.
• Goggles are mandatory for eye protection when handling heat, chemicals, or glassware.
• Pinch clamp secures rubber tubing to control fluid flow during experiments.

Support and Structural Equipment

• Ring clamp fastens beakers or other containers to a ring stand for stability during heating.
• Striker is a tool used to ignite a Bunsen burner safely and effectively.
• Test tube rack holds multiple test tubes upright, ensuring they do not tip over during analysis.

Weighing Tools

• Weigh boats provide a clean surface for weighing out chemicals on a balance, minimizing contamination.
