it is used to dispense small amount of liquids
Dropping Pipet
It is used to protect chemicals which are hydroscopic or which react with water from humidity.
Dessicator
It is used for precise weighing of solids.
Weighing bottle.
It is used for distillation and reflux experiments. It allows for the vapor to cooled back to a liquid.

Adapter
It is used to hold small quantities of substances which are undergoing direct heating by a bunsen burner or other heat sources.
Hard glass tube/Ignition Tube
It is used to hold specimen for observation and to grow cultures.
Petri Dish
It is used in holding large amount of chemical during heating at very high temperatures.
Porcelain casserole.
It is used in holding small amount of chemicals during heating at a very high temperature.
Porcelain crucible
It is used to perform reactions on a small amount of materials. several small depressions for use in a spot test. Also known as reaction plate
Spot plate
It is used in pressure-assisted filtration.
Buchner Funnel
It is used in crushing and grinding of materials
Mortar and Pestle
It is used to heat samples for evaporation
Evaporation Dish
It is used to support the wire gauze and glassware whhile heating.
Tripod
It is used to hold or clamp laboratory glassware and other equipment in place, so it does not fall down or come apart.
Iron Stand
It is used with a ring stand to hold glassware, such as a beaker or a funnel.
Iron ring
It is used to hold and support the buret during titration.
Buret clamp
It used to support a crucible during heating
Clay triangle
It is sed to secure laboratory clamps to a ring stand or lab frame
Clamp holder
It is used to hold crucibles (pababa ang scissor)
Crucible tong
It is used to secure glassware to a ring stand
Other types of clamps
It is used to hold a test tube, probably when hot.
Test tube holder
It is used to support a container, such as a beaker, or a ring stand while it is being heated.
Wire gauze
It is used to produce an open flame. It uses ethyl alcohol or spirit as a fuel. It can be made from brass, glass, stainless steel or aluminum
Heat source
It is used as a heat source when an open flame is not desirable.
Hot plate
It is used to furnish heat in the laboratory, it works by mixing a fuel gas with air, so that the gas will burn with the hottest flame possible
Burner
It is used to measure small mass in the sub-milligram range.
Analytical Balance
It is used for measuring mass, is used to read the mass of items. It has a 3 beams.
Beam Balance
It is used to scoop and transfer a solids
Spatula and Spoons
It is used with a bunsen burner to make a flat , broad flame, fish tail.
Wing top
It is used to hold several test tubes one at a time.
Test tube rack
It is used to clean test tubes.
Test tube brush
It is used for cutting a hole in a cork or a rubber stopper to insert a glass tubing.
Cork borer
It is used to trim, sharpen edges and score glass bbefore cutting.
Triangular File
It is used for compressing a flexible pipe or rubber tube, in order to regulate or stop the flow of a liquid.
Pinch cock
It is used to draw liquids into a pipe.
Aspirator/Pipet bulb
It is used in the flowlines for fluids and gases. It is flexible and resilient due to its natural or synthetic rubber construction.
Rubber tubing
It is used to pick up or hold small objects
Forceps
It is used to rinse pieces of glassware and to add small quantities of water.
Wash Bottle
It is used to measure temperature.
Thermometer
It is used to measure the acidity or alkalinity level of the sample expressed in pH
