\

• Beaker
  • Used for stirring, mixing, or heating liquids.
• Erlenmeyer Flask
  • Used to mix, heat, and store liquids. These flasks are not used to accurately measure volumes of liquids.
• Pipette
  • Come in various sizes and are used to transport accurate volumes of liquids.
• Pipette Bulb
  • Pipet bulbs are used to draw liquids into the pipet.
• Burette
  • Is used to dispense accurate volumes of liquids.
• Graduated Cylinder
  • Used to measure volumes. To accurately read the volume of a liquid, read the bottom of the meniscus.
• Test Tube
  • Used to hold, mix or heat very small amounts of solids or liquids.
• Test Tube Rack
  • Test tube racks hold and help organize test tubes during experiments.
• Test Tube Holder (Tongs)
  • Is used to hold a test tube when it’s hot or when it’s not safe to use the hands.
• Ring Stand
  • Provides a safe base to hold and clamp glassware and pieces of lab equipment.
• Wire Gauze
  • Placed over the ring clamp to support beakers and flasks over a flame
• Clay Triangle
  • Used to support a funnel or crucible with an iron ring
• Crucible Tongs
  • Hold Crucibles only. They have long handles and the tips are serrated to give better grip.
• Crucible and Cover
  • Small porcelain container used to heat substances to very high temperatures.
• Evaporating Dish
  • This is used to get the water out of a solution, evaporate out the water. The watch glass is placed on top to prevent spilling.
• Watch Glass
  • Used as a surface to evaporate liquids, to hold solids that are being weighed, or to cover beakers.
• Wash Bottle
  • Used in the clean up phase of an experiment.
• Volumetric Pipette
  • To transfer that volume of liquid for use in creating a solution or dilution.
• Volumetric (Florence) Flask
  • Used as a surface to evaporate liquids, to hold solids that are being weighed, or to cover beakers.
• Temperature and Pressure Probes
  • Measure the stagnation pressure, the static pressure, and the flow angle within a fluid stream.
• Barometer
  • To measure atmospheric pressure
• Funnel
  • Used to channel liquids into containers that have small openings.
• Test Tube brush
  • Used to clean test tubes and graduated cylinders.
• Glass Stirring Rod
  • Used to stir and decant solutions.
• Bunsen burner
  • Used to heat solutions and other chemicals in the lab.
• Forceps
  • Used to pick up small items.
• Ring Clamp
  • Attached to the ring stand to support and hold glassware such as crucibles beakers
• Mortar and Pestle
  • A bowl made of ceramic to crush and grind soils.
• Spatula
  • Transport and distribute dry chemical compounds
• Scoopula
  • Utensil used in chemistry to \n transfer solids.
• Rubber Stoppers
  • These come in all different shapes and sizes and they are used to seal off a container.
• Tripod
  • Lab a piece of equipment that supports other equipment like the clay triangle or wire mesh that can be used of the ring stand.
• Beaker Tongs
  • These are used to carry hot beakers after heating.
