Pipette
A pipette transfers controlled amounts of liquid from one container to another.
Burette
A burette has a long graduated tube and a valve near the bottom. It dispenses measured amounts of liquid with good control.
Funnel
A laboratory funnel has a wide opening and narrow stem. It helps guide liquids or fine materials into smaller containers.
Dropper
A dropper transfers small amounts of liquid one drop at a time.
Watch Glass
A watch glass has a shallow circular shape. Laboratory workers use it to hold small samples or cover containers.
Glass Rod
A glass rod helps stir liquids and guide liquid while pouring.
Crucible
A crucible holds materials during strong heating. Manufacturers make it from heat-resistant material.
Evaporating Dish
An evaporating dish has a broad shallow shape that helps expose liquid to heat and air.
Mortar and Pestle
A mortar forms the bowl, while the pestle provides the grinding surface. Together, they crush or grind solid materials.
Spatula
A laboratory spatula handles or transfers small amounts of solid material.
Test Tube Rack
A test tube rack keeps several test tubes upright and organized.
Test Tube Holder
A test tube holder grips a single tube securely during laboratory work.
Ring Stand
A ring stand combines a heavy base with a vertical metal rod. It supports clamps, rings, and other apparatus.
Tripod Stand
A tripod stand uses three legs to support containers above a heat source or other apparatus.
Wire Gauze
Wire gauze rests on a support stand and holds laboratory containers above a heat source.
Thermometer
A laboratory thermometer measures the temperature of liquids, gases, and other materials.
Digital Balance
A digital balance measures the mass of laboratory samples and displays the result electronically.
Microscope
A microscope magnifies very small objects so users can observe details that the unaided eye cannot see.
Petri Dish
A Petri dish has a shallow round shape and a fitted lid. Biology laboratories use it to hold and observe samples.
Wash Bottle
A wash bottle has a squeezable body and narrow angled nozzle. Users press the bottle to direct a small stream of liquid.
Reagent Bottle
A reagent bottle stores laboratory chemicals or prepared solutions.
Laboratory Glassware and Containers
Laboratory glassware comes in different shapes depending on whether the user needs to hold, measure, mix, separate, or heat a substance.
- Volumetric Flask holds one specific calibrated volume of liquid.
- Round-Bottom Flask has a spherical body that spreads heat more evenly around its contents.
- Separatory Funnel separates certain liquid layers with the help of a lower valve.
Shape, neck width, markings, and outlets usually provide the clearest visual clues for telling one piece of glassware from another.
Measuring and Weighing Instruments
Laboratories use measuring instruments when experiments require more precision than rough visual estimates.
- Analytical Balance measures mass with high sensitivity and precision.
- Triple Beam Balance uses sliding weights on three beams to determine mass.
- pH Meter measures how acidic or alkaline a liquid is.
- Vernier Caliper measures external, internal, and depth dimensions precisely.
- Micrometer Screw Gauge measures very small thicknesses and diameters.
- Spring Balance measures force or weight through spring extension.
- Stopwatch measures short time intervals during experiments and observations.
Liquid Measuring and Transfer Tools
Scientists use several tools to move liquids safely and control the amount they transfer.
- Micropipette transfers very small measured liquid volumes.
- Pipette Filler helps users draw liquid into compatible pipettes without direct mouth contact.
Pipettes, burettes, droppers, and graduated cylinders all handle liquids, but each tool offers a different level of measurement and control.
Laboratory Heating Equipment
Laboratory heating equipment ranges from simple burners to electrically controlled devices. Users choose the type according to the level and style of heating required.
- Bunsen Burner produces a gas flame for laboratory heating.
- Spirit Lamp uses a wick and liquid fuel to produce a small flame.
- Hot Plate provides heat through a flat electric surface.
- Heating Mantle surrounds compatible vessels and provides controlled electrical heating.
- Water Bath warms containers gently through heated water.
Holding and Support Apparatus
Support apparatus keeps laboratory equipment stable and correctly positioned.
- Iron Ring attaches to a ring stand and supports compatible apparatus.
- Utility Clamp holds laboratory items in place on a support stand.
- Burette Clamp secures one or more burettes in an upright position.
- Crucible Tongs grip hot crucibles or similar containers.
Their jaws, handles, frames, and attachment points usually make these support tools easy to recognize.
Mixing and Grinding Tools
Laboratories use simple and powered tools to stir, mix, crush, and handle solid or liquid substances.
- Scoopula transfers small amounts of powders and crystals.
- Magnetic Stirrer rotates a magnetic stir bar inside a liquid.
- Vortex Mixer rapidly agitates small containers to mix their contents.
A mortar and pestle also belongs to this broad group because it crushes solid materials into smaller particles.
Biology Laboratory Equipment
Biology laboratories use specialized equipment to examine cells, microorganisms, tissues, and other biological samples.
- Microscope Slide supports a specimen during microscope viewing.
- Cover Slip covers a specimen on a microscope slide.
- Dissecting Tray provides a stable surface for supervised biological examination work.
- Centrifuge spins samples quickly to separate components according to physical properties.
- Incubator maintains controlled environmental conditions for selected biological samples.
Microscopes and Petri dishes also play major roles in biology laboratories.
Physics Laboratory Instruments
Physics laboratories use measuring devices to study electrical and mechanical quantities.
- Ammeter measures electric current.
- Voltmeter measures electrical potential difference.
- Galvanometer detects and measures relatively small electric currents.
Physics laboratories also use spring balances, stopwatches, Vernier calipers, and micrometers for mechanical measurements.
Powered and Specialized Laboratory Equipment
Modern laboratories often use powered equipment for analysis, sterilization, mixing, and controlled testing.
- Spectrophotometer measures how much light a sample absorbs or transmits at selected wavelengths.
- Colorimeter measures color intensity or light absorption in certain samples.
- Autoclave uses high-temperature steam under controlled conditions to sterilize suitable laboratory materials.
Research, medical, industrial, and advanced teaching laboratories commonly use this type of equipment.
Laboratory Safety Equipment
Safety equipment protects laboratory users and supports emergency response when something goes wrong.
- Safety Goggles protect the eyes from splashes and particles.
- Eyewash Station provides flowing water for emergency eye rinsing.
- Safety Shower provides emergency water flow over the body.
- Fire Extinguisher helps control certain types of small fires.
- Fume Hood draws hazardous fumes and vapors away from the working area.
These items belong in a separate safety category because their main purpose is protection rather than measurement or experimentation.
