No Name Description Function Picture

1. Beaker Glass A cylindrical container, has a scalar used for measuring solution (Not quite accurate)

 A Container to dissolve substances.

 Used to collect filtrates from filtering

operations as well as liquids from titrations.

 A place for stirring the liquid.

2. Beaker

Tongs A handler, has a single hand gripper like a scissors.

Usually, and recommended to be placed at the middle of the beaker.

 To handle hot beakers safely.

3. Erlenmeyer

Flask A container, has a flat bottom, a conical body, and cylindrical neck. Also has a scalar in its body, used for measuring solution (Not quite accurate)

 Used for making solutions or for holding, containing, collecting, or either for measuring chemical

volumetrically.

 For chemical reactions or other processes, e.g:

mixing, heating, cooling, dissolving, precipitation, boiling (as in distillation), or analysis.

4. Reaction Flask

Spherical (i.e.

round-bottom flask),

companied by their necks, at the end of which are ground glass joints to quickly and tighly, connect to the rest of the apparatus (f.e. a reflux

condenser or dropping funner)

 To keep both in a reaction under vacuum, and pressure,

sometimes silmutaneously

5 Multiple

neck flasks Has multiple neck, can have two to five necks, less commonly six necks. Each topped by ground glass connections which are use in more complex reactions that require the controlled mixing of multiple reagents

 Multiple necks flask I some varieties of the reaction flask

6 Schlenk Flask

A ground glass opening and a hose outlet and a vacuum stopcock.

 To connect the flask to a vacuum-nitrogen line through the hose and to facilitate either in vacuum or in an atmosphere of nitrogen easily.

7. Büchner

Flask Known as a

vacuum flask, filter flask, suction, side- arm flask, kitasato flask or Bunsen flask. A thick-walled Erlenmeyer flask with a short glass tube and hose barb protruding about an inch from its neck.

 The short tube and hose barb act as an effective adapter over which the end of a thick-walled flexile hose (tubing) can be fitted to form a connection to the flask.

 The other end of the hose can be connected to source of vacuum such as an aspirator, vacuum pump, or house vacuum.

 To prevent the sucking back of water from the aspirator into the Büchner flask.

8. Volumetric Flask

Pear-shaped, with a flat bottom, and made of glass or plastic

 To make up a solution to a know volume.

 To measure volumes of liquid materials for laboratory experiments much more precisely than beakers or Erlenmeyer flasks

9. Vacuum

Flask An insulating storage vessel that greatly lengthens the time over which its contents remain hotter or cooler than the flask’s

surrounding.

Consists of two flasks, placed one within the other and joined at the neck.

 To hold liquified gasesmfor flash freezing, sample preparation, ad other processes where maintaining an extrem low temperature is desired.

10

. Burette a graduated glass tube with a tap at one end, It is a long, graduated glass tube, with a stopcock at its lower end and a tapered

capillary tube at the stopcock's outlet.

 Used in quantitative chemical analysis to measure the volume of liquid or a gas

 for delivering known volumes of a liquid, especially in titrations.

11 .

Burette Clamp

Has two clamp, used for hold 2 burretes

 Used to hold two burets once it attached to a ring stand, Burets in the clam are free to move up and down or to spin so that they fit your height and handedness needs

12 .

Ring Stand Made from a metal stand consisiting of a long upright rod attached to a heavy

rectangular base that is used with rings and clamps for supporting laboratory apparatus.

 Used to hold or clamp laboratory glassware, and other equipment. In place, so it does not fall down or come apart

13

. Mortar and

pestle A set of two simple tools.

The mortar is charastically a bowl. The pestle is a blunt, club-shaped object

 Softens substances that are still in solid or crystalline form

14

. Filler pipette A small glass or plastic tubes for transferring precise volumes of liquids.

 To draw liquids into the pipette

 Also used to draw non- liquid substances

15 .

Pipette Dropper

A chemical dropper, small glass or plastic tubes to transmareat

 Used to transfer measurable amount of liquid

16 .

Measuring Glass

A graduated

glass container.  Used to measure quantities of liquid

17 .

Petri Dish A shallow transparent lidded dish

 c

18

. Desiccator Sealable enclosure containing desiccants.

Circular, and made of heavy glass

 Used for preserving moisture-sensitive items

 To protect chemicals which are hygroscopic or which react with water for humidity

 Used to remove traces of water from an almost-dry sample

19

. Condensers A long tube through which the vapors are directed, with the outside air providing the cooling. Has a separate tube or outer chamber through which water is circulated, to provide a more effective cooling

 Used to condense vapors, that is turn them into liquid by cooling them down

 Used for distillation, reflux, and extraction.

20

. Graduated

Cylinders A graduated cylinder, known as measuring cylinder or mixing cylinder.

 Used to measure the volume of a liquid.

21 .

Bottles A container with narrow openings generally used to store reagents or samples

Used to store reagent or sample.

22 .

Jars/Bell Jars Cylindrical containers with wide openings that may be sealed

 Bell jers are used to containing vacuum

23

. Vials Small Bottles  Used as scientific sample vessel. E.g. in autosampler device in analytical

chromatography

24

. Test Tubes Made from expansion- resistant glasses, mostly borosilicate glass or fused quartz. Has flat botton, around bottom, or a conical bottom.
