3. Test Tubes
Used for holding, mixing, or heating small quantities of substances. They can be closed with a stopper to prevent contamination.
Measuring Instruments 📏
1. Graduated Cylinder
A tall, narrow container used to measure the volume of liquids accurately.
2. Pipette
Used to transfer small amounts of liquid with precision.
3. Burette
A long, graduated glass tube with a tap at one end, used for dispensing precise volumes of liquid.
Heating Equipment 🔥
1. Bunsen Burner
A common piece of equipment used to heat substances with a flame.
2. Hot Plate
An electrical device used to heat substances without an open flame, providing a safer option.
Safety Equipment ⚠️
1. Safety Goggles
Protective eyewear to safeguard against chemical splashes and debris.
2. Lab Coats
Protective garments worn to keep clothing and skin safe from spills and splashes.
3. Fume Hood
A ventilated enclosure used to handle hazardous materials and protect users from exposure.
