• Lab equipment is an important part of science in general.• Since science is divided into pure and applied parts, experiments are very important.• Equipment are used to carry out experiments with ease.
Classification• Equipment can be classified into different categories usually based on the material they are made of. Glasswares Porcelainwares Others
GlasswaresBeaker• Used to hold and heat liquids. Multipurpose and essential in the lab.Test Tube• Used by chemists to hold, mix, or heat small quantities of solid or liquid chemicals, especially for qualitative experiments.
Florence Flask• Used for heating subtances that need to be heated evenly. The bulbed bottom allows the heat to distribute through the liquid more evenly. The Florence Flask is mostly used in distillation experimentsErlenmeyer Flask• Used to heat and store liquids. The advantage to the Erlenmeyer Flask is that the bottom is wider than the top so it will heat quicker because of the greater surface area exposed to the heat.
Funnel• When lined with filter paper, used to filter suspended solids from a liquid.Graduated Cylinder• Used to make accurate measurements of liquid volumes.Stirring Rod• The stir rods are used to stir things. They are usually made of glass.
Watch Glass• Convex-concave piece of glass used in chemistry as a surface to evaporate a liquid, to hold solids while being weighed, or as a cover for a beaker.Petri Dish• Used for holding a culture medium upon which cells, bacteria, and viruses can be grown and studied.
PorcelainwaresCrucible and Cover• Used to heat chemicals (usually solids) to high temperatures. This may be necessary to dry a solid completely.Evaporating Dish• Used to evaporate the liquid away from a small volume of solution.
Mortar and Pestle• Used to grind solid chemicals into smaller pieces. By grinding solid chemicals into smaller pieces, the solid may dissolve or react with other chemicals more quickly.Spatula• used for moving small amounts of solid from place to place
Others• The “other” equipment can be further classified as ACCESSORY or for SPECIAL SET- ups.• Some special Set-ups include distillation, titration, filtration etc.
AccessoriesBrushes• Coarse bristles to scrub and clean glassware and other equipment. They come in many different sizes, depending on the item being cleaned.Crucible Tongs• Used for handling crucibles, evaporating dishes, and other hot objects.
Test Tube Rack• Used for holding test tubes upright when they contain chemicals, and also hold test tubes upside down to dry.Test Tube holder• Used to hold and transport hot test tubes.Thermometer• Used to measure the temperature of substances.
Set-Ups• Equipment involved in set-ups are usually used for that special purpose alone.• Basic set-ups are essential in performing experiments.
HeatingClay Triangle• Used to support crucibles when heating them.Wire Gauze• Used for supporting beakers and flasks when they are being heated with a Bunsen Burner
Bunsen burner/ Alcohol lamp• Used for heating chemicals and equipment.Iron ring• Used to support laboratory equipment above the work surface.Iron stand• Used to provide support for other equipment and a means of raising equipment above the work surface.
MicroscopyMicroscopes• various powers are the most common of the biology lab equipments used in bio labs to see organisms and samples more closely.SlidesIn a biology lab, cells are gently smeared onto a glass slide, treated with a fixative so that the cellular component is seen clearly.
Distillation• A method of separating mixtures based on differences in volatilities of components in a boiling liquid mixture.
Distilling Flask• The distilling flask is used to separate liquid mixtures by distillation.Condenser• Used to cool gases to a point where they will liquefy, or condense, back into their liquid form, so that they may be collected in a separate container.
Titration• A common laboratory method of quantitative chemical analysis that is used to determine the unknown concentration of an identified liquid.
Burette• Used in titrations to measure precisely how much liquid is used.
