Frequently Asked Questions
What is the purpose of a beaker in a laboratory setting?
A beaker is used for mixing, stirring, and heating liquids. It provides a convenient way to hold and measure volumes of liquid.
How do you properly use a graduated cylinder?
To properly use a graduated cylinder, place it on a flat surface, pour the liquid in, and read the measurement at eye level at the bottom of the meniscus.
What safety equipment is essential when using lab equipment?
Essential safety equipment includes safety goggles, lab coats, gloves, and in some cases, face shields and fume hoods to protect against chemical exposure.
What is the difference between a pipette and a dropper?
A pipette is used for precise measurement and transfer of small volumes of liquid, while a dropper is less precise and typically used for adding small amounts of liquid dropwise.
Why is it important to calibrate lab equipment?
Calibrating lab equipment is important to ensure accuracy and reliability of measurements, which is crucial for reproducible experimental results.
What should you do if you break glass lab equipment?
If you break glass lab equipment, do not attempt to pick up the pieces with bare hands. Use a dustpan and brush to clean it up and dispose of the shards in a designated glass waste container.
What is the function of a Bunsen burner in the lab?
A Bunsen burner provides a single open flame that can be used for heating, sterilization, and combustion in laboratory experiments.
How do you clean and maintain lab equipment?
Lab equipment should be cleaned immediately after use with appropriate cleaning solutions, rinsed thoroughly with distilled water, and dried to prevent contamination and wear.
