Petri dish:

  • Is a shallow transparent lidded dish.
  • It is also known as petri plate or cell culture dish.
  • Petri dish or petri plate was discovered by Sir Julius Richard Petri.
  • It is used to culture cells of different microorganisms such as bacteria, fungi and small mosses.
  • Diameters ranging from 30-200 mm.
  • It is usually made up of borosilicate glass.


  • In microbiology for culture of microorganisms.
  • In cell culture for cultivation of isolated cells.
  • In sample storage and display.

Conical flask:

  • It is a type of flask which have a conical body with flat bottom and a cylindrical neck.
  • It is also known as Erlenmeyer flask or a titration flask.
  • It is named after scientist Emil Erlenmeyer.


  • In microbiology, it is used for the preparation of microbial culture.
  • In chemistry, it is commonly used for mixing by swirling during titration and other solvents.


  • It is a laboratory equipment or glassware.
  • It is generally container with flat bottom and cylindrical in shape and also have small beak to aid pouring.
  • They are made up of glass [Borosilicate glass] or certain plates.

It is of three types:

  • A low from or Griffin from beaker.
  • A tall from or Berzelius beaker.
  • A flat beaker or Crystallizer.

It is commonly used for diluting concentrated chemicals make buffers or catch products during an experiment.

Test tube:

  •  It is a finger –like length made up glass or plastic, which is closed at the bottom and open at the top.
  • It is also referred as Culture tube or Sample tube.
  • It is generally made up of Borosilicate glass.


  • In Bioscience for handling and culturing of different organisms.
  • In chemistry commonly used for handling of chemicals.


  • It is a laboratory tool, sometimes also termed as pipet
  • It is commonly used in biology, medicine and chemistry labs for transfer of measured volume of liquid.
  • Pipettes ranges from 1-1000 µL are distinguished as Micropipettes and Macro pipettes.
  • Heinrich Schnitger was first to patent micropipette in 1957.

Graduated Cylinder:

  • It is commonly laboratory glassware which is used to measure the volume of liquid.
  • It has a narrow and cylindrical in shape.
  • Graduated cylinder also known as mixing or measuring cylinder.
  • Graduated cylinder are made up of Polypropylene.


  • It is a tube that is narrow at the bottom and wide at the top.
  • It is commonly made up of stainless steel, aluminum, glass, or plastic.


  • used for pouring liquids or powder.
  • used for holding filter paper in filtration.
  • used in transferring liquid in small container.

Glass slides or Microscope slides:

  • It is flat piece of glass.
  • It is commonly used for the examination under microscope.
  • A standard microscope slides ranges from 75mm by 25mm and 1mm thick.

Centrifuge tubes:

  • It is generally plastic or glass tube which is used for containing liquid during centrifugation.
  • It is usually made up of Polypropylene.

Inoculating loop:

  • It is simple laboratory tool used by microbiologists.
  • It is also known as smear loop or, micro-streaker.
  • It is generally made up of metal wire [such as Nicrome, platinum or tungsten].
  • Inoculating loop used for transferring a small sample or inoculum from a culture of microorganisms.
  • It is also used in streaking on a culture plates.
