Study Notes
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.
