Study Notes

Scientific Tools Overview

Flint Striker: Device used to ignite Bunsen burners through sparks generated from a rough surface and flint.
Funnel: Conical utensil designed to channel substances into small containers via a narrow tube at the apex.
Beaker & Beaker Tongs: Beakers are containers for stirring and measuring liquid volume in mL; tongs are for handling hot beakers safely.
Evaporating Dish: Small porcelain or borosilicate glass bowl with a spout, used mainly for evaporating solvents from samples.
Stopper: Rubber stopper is used to seal flasks and test tubes, especially in fermentation processes.
Test Tube: Cylindrical glassware, open at the top, closed at the bottom, used for holding small volumes of liquid samples.
Test Tube Clamp: Instrument designed to clamp onto a ring stand for securing test tubes or beakers during experiments.
Lab Burner Screen/Wire Mesh: Supporting wire gauze used under beakers on a stand to evenly distribute heat from a Bunsen burner.
Spot Plate/Well Plate: Laboratory tool with cavity depressions to conduct reactions with small quantities of reactants.
Wash Bottle: Squeeze bottle with a nozzle used for rinsing laboratory glassware.
Bunsen Burner: Produces a single open flame for heating and sterilization, fueled by natural or liquefied petroleum gas.
Tube Cleaner: Utilizes cleaning chemicals to remove deposits from laboratory tubes.
Pipette: Common laboratory tool for transporting or dispensing measured volumes of liquid.
Crucible Tongs: Specialized scissor-like tongs with pincers used for handling hot crucibles or glassware.
Clay Triangle: Wire apparatus used to support a crucible during heating with a Bunsen burner.
Support Stand with Rod (Ring Stand): Equipment supporting clamps and holds devices like burettes or test tubes for experiments.
Scoopula: Spatula-like tool used to transfer solid substances in laboratory settings.
Forceps: Tool for grasping small objects when fingers are too large or when multiple objects need to be held.
Conductivity Meter: Measures conductance as the inverse of resistivity, commonly used in electrical studies.
Mortar and Pestle: Device for crushing and grinding substances into pastes or powders, used since ancient times.
Digital Temperature Probe: Stainless steel sensor measuring temperature in various solutions for multiple scientific experiments.
Utility Clamp: Scissor-like device to securely hold laboratory equipment in place.
Graduated Cylinder: Tall, narrow container marked with measurements, used for accurately measuring liquid volumes.
Watch Glass: Concave glass used for evaporating liquids, weighing solids, and covering beakers during heating.
Glass Stirring Rod: Solid glass rod used for mixing solutions in laboratory experiments, akin to a thicker straw.
Burette Clamp: Specific clamp designed to hold burettes securely on a stand for convenient use in titrations.
Beaker: Versatile container for mixing, stirring, and heating liquids in laboratory settings.
Erlenmeyer Flask: Conical flask for mixing and storing liquids, featuring a flat bottom and a narrow neck.
King Clamp: Tongs-like device used for grasping or holding laboratory equipment securely.
