Study Notes
Beaker
- Used for pouring, storing, mixing, heating, and dispensing
- Not used for precise measurements
- Features a "beak" for pouring
Flask
- Used for holding solids or liquids that may release gas during reactions or splatter easily when stirred or heated.
- Not designed for precise measurements
Florence Flask
- Used for holding liquids
- Not used for accurate measurements
Volumetric Flask
- Laboratory glassware calibrated for precise volume at a specific temperature
- Used for accurate dilutions and preparing standard solutions
- Typically pear-shaped with a flat bottom, made of glass or plastic
Graduated Cylinder
- Used for measuring liquids
- Not suitable for chemical reactions
- Measurements are taken from the curve of the meniscus
Test Tubes
- Used for holding liquids and chemicals during experiments
- Used for storing, mixing, and heating
- Not used for precise measurements
- Should be held using tongs or clamps, never by hand
Burette
- Vertical cylindrical piece of laboratory glassware
- Graduated for precise measurement of liquid volumes
- Fitted with a tap to dispense known amounts of liquid
Meniscus
- Curved surface of a liquid in a cylinder
- Caused by adhesion between the liquid and container and cohesion between liquid particles
- Used for taking measurements in graduated cylinders, beakers and other vessels
Test Tube Holder
- Useful for holding hot test tubes
- Prevents burns
Test Tube Brushes
- Used to clean test tubes and graduated cylinders
Test Tube Racks
- Used for holding and organizing test tubes
- Plastic racks may melt if exposed to extreme heat
Rubber Stoppers
- Used to seal containers to prevent spillage or contamination
- Should not be used when heating containers
Spot Plates
- Used for performing multiple small-scale reactions
Watch Glass
- Used to hold small amounts of solid substances, often the product of a reaction
Glass Stir Rod
- Used to manually stir solutions
- Can transfer small drops of solution
Stirring Rod
- Used for mixing chemicals and hot liquids
Medicine Dropper
- Used for transferring small volumes of liquid (less than 1 mL)
- Typically includes a rubber bulb
Litmus Paper
- Used to identify acids (blue litmus turns red) and bases (red litmus turns blue)
Funnel
- Used to aid in the transfer of liquid from one container to another
Mohr Pipet
- Used for measuring and delivering precise volumes of liquid
Micropipette
-
Used for accurate and precise transfer of liquid samples in the microliter range
-
Available in single channel and multichannel versions
-
Single Channel or Multichannel Micropipettes are selected based on the number of samples or replicates
-
Tips can be conical or cylindrical, universal or pipette specific, filtered or non-filtering, and graduated
Wash Bottle
- Delivers wash solution to a specific area
- Primarily used with distilled water
Weighing Boat
- Used for weighing solids before transferring them to another container
Spatulas
- Used to dispense solid chemicals from their containers
- Chemicals should never be transferred with bare hands
Beaker Tongs
- Used to move beakers containing hot liquids
Bunsen Burner
- Used for heating non-volatile liquids and solids
Hot Plate
- Used for heating substances using electricity
Ring Stand
- Used to hold containers away from a heat source (like a Bunsen burner) during experiments
Iron Ring
- Connects to a ring stand, providing a stabilized platform for reactions
Utility Clamps
- Used to secure test tubes, distillation columns, and burets to the ring stand
Double Buret Clamps
- Used to secure burets (long graduated tubes used in titrations)
Laboratory Centrifuge
- Device driven by a motor that spins liquid samples at high speed
- Used to separate substances of different densities
