Laboratory Apparatus

Basic Equipment's

Graduated Cylinders

is a tool for **measuring liquid volumes** in a lab, with a narrow shape and marked lines

Microscope

1. **an optical instrument used for viewing very small objects, such as mineral samples or animal or plant cells, typically magnified several hundred times.**

Beaker

are vessels in which liquid is placed so it can be stirred, mixed or heated. They come in a variety of shapes, sizes and materials depending on the application, and can be reusable or disposable.

Bunsen Burner

consisting typically of a straight tube with small holes at the bottom where air enters and mixes with the gas to produce an intensely hot blue flame.

Test Tubes

is a common piece of laboratory glassware consisting of a finger-like length of glass or clear plastic tubing, open at the top and closed at the bottom.

Droppers

these devices look like thin tubes made of plastic or glass, tapering off to a narrow end. They usually have a rubber or plastic bulb at the end for facilitating liquid intake.

Glass Stirring Rod

is a piece of laboratory equipment used to **mix chemicals**. They are usually made of solid glass, about the thickness and slightly longer than a drinking straw, with rounded ends.

Digital Balance

are devices used to precisely measure the mass of an object.

Conical Funnel

It is used for the **separation of different kinds of chemicals like oils, detergents, solvents, inorganic solids, and various minerals**. It is available in two shapes: the wide neck and the narrow neck.

Spatulas

are used to **measure solids, move objects and scrape material from beakers**.

Test Tube Rack

used to **hold upright multiple test tubes at the same time**.

forceps

are the **"tweezers" in an organic chem lab**.

Safety Googles

play a critical role in protecting a worker’s eyes, especially when an individual works with chemicals, machinery, laser light and biological hazards.

Volumetric Flask

is a piece of laboratory apparatus, a type of laboratory flask, calibrated to contain a precise volume at a certain temperature.

Conical Flask

uses include **mixing and heating solutions, short term storage and for research involving testing accessories such as chemical probes and sensors**

Boiling Flask

also known as a round bottom flask, is a chemical vessel with a spherical body and a cylindrical neck.

Burettes

**dispense and measure variable amounts of liquid or sometimes gas within chemical and industrial testing** specially for the titration process in volumetric analysis.

Thermometer

measure temperature with a high level of precision for applications such as experiment monitoring, instrument calibration, materials testing, and maintaining a sterile work environment.

Separating Funnel

are used in the lab for **liquid-liquid extractions**, separating a mixture's components into two solvent phases of different densities.

Pipette

is a small tube that can transfer liquids from one container to another and is a common piece of **laboratory** equipment.

Mortar and Pestle

is predominantly used to **crush and blend substances together**.

Watch Glass

used to **hold solids during weighing**.

Slides

is a thin flat piece of glass, typically 75 by 26 mm (3 by 1 inches) and about 1 mm thick, used to hold objects for examination under a microscope.

Tongs

are large pincers for **grasping and lifting vessels of heat-resistant material used in high temperature chemical reactions**.

Erlenmeyer flasks

their slanted sides and narrow necks allow the contents to be mixed by swirling without the risk of spills, which is useful for titrations and for boiling liquids.

Syringe

is a laboratory apparatus that is used to **measure and transfer small amounts of liquid**.

Magnifying Glass

it is used to **view enlarged or magnified images of objects or read the small calibrations marked on many equipments**.

Tripod

is a portable, three-legged platform equipment, which is usually made of lightweight metal such as stainless steel or aluminium so that it can be moved conveniently within the lab.

Coverslips

are small squares of glass that cover the specimen placed on the microscope slide.

Ring Clamp

hey are used to **stabilize or support items such as separatory funnels, or to hold beakers over open flames**.
