Used to hold and mix liquids.

CLAY TRIANGLE

Used to support a crucible during heating

TEST TUBE CLAMP

Used to hold a test tube, particularly when hot.

CRUCIBLE

Used for holding chemicals during heating to very high temperatures.

TEST TUBE RACK

Used to hold several test tubes at one time.

CRUCIBLE TONGS

Used to hold crucibles.

THERMOMETER

Used to measure temperature in Celsius.

ERLENMEYER FLASK

Used to hold and mix chemicals. The small neck is to facilitate mixing without spilling.

UTILITY CLAMP

Used to secure glassware to a ring stand.

EVAPORATING DISH

Used to heat liquids for evaporation.

VOLUMETRIC FLASK

Used to prepare solutions to an accurate volume.

RING CLAMP

Used with a ring stand to hold glassware, such as a beaker or a funnel.

FORCEPS

Used to pick up or hold small objects.

VOLUMETRIC PIPETTE

Used to measure small amounts of liquid very accurately.

WASH BOTTLE

Used to rinse pieces of glassware and to add small quantities of water.

FUNNEL

Used to transfer liquids or fine-grained materials into containers with small openings. Also used for filtration.

GRADUATED CYLINDER

Used to measure a precise volume of a liquid.

WATCH GLASS

Used to hold solids while they are being weighed or to cover a beaker.

MORTAR AND PESTLE

Used to crush and grind materials.

WIRE GAUZE

Used to support a container, such as a beaker, on a ring stand while it is being heated. May have a fiberglass or ceramic center.

ASPIRATOR

used for moving air, fluids, etc. by suction. Also known as an eductor-jet pump, or a filter pump.

BUCHNER FUNNEL

is a piece of laboratory equipment used in suction filtration under reduced pressure.

BURETTE CLAMP

A buret clamp is chemical or biological laboratory equipment. It is used for firmly holding test-tubes, burettes and other glassware in place when performing experiments such as titration

CONDENSER

Laboratory apparatus used to condense vapours back to liquid so that the liquid can be recovered. It is used in distillation and in reactions where the liquid mixture can be kept boiling without the loss of solvent.

FILTER PAPER

It is usually used with a filter funnel, Hirsch, or Buchner funnel. Ashless filter paper is mainly used for gravimetric methods in quantitative chemical analysis.

GLASS TUBING

Glass tubing is used to connect other pieces of lab equipment. It can be cut, bent and stretched for a variety of uses.

LITHMUS PAPER

Litmus paper is used for measuring the pH of a liquid. The pH is a measurement of how acidic or basic a liquid is.

PH METER

The pH meters measures the activities and not the concentrations of hydrogen ions.

REAGENT BOTTLE

It is used to put in chemical substances, solutions, or solvents.

RUBBER STOPPER

The primary purpose of a rubber stopper is to prevent a gas or liquid from escaping its container during a scientific experiment. Rubber stoppers can also prevent the contamination of samples by protecting the contents of laboratory glassware from air. Last, the use of rubber stoppers allows experimenters to shake or mix solutions without spilling them.

RUBBER TUBING

Rubber tubing is often connected to a condenser, which is a laboratory tool used in the process of distillation. The rubber tubing helps cool water to flow in and out of the condenser and helps the heated water vapour in the condenser return to its liquid state.

SEPARATORY FUNNEL

is a piece of laboratory glassware used in liquid-liquid extractions to separate (partition) the components of a mixture between two immiscible solvent phases of different densities.

SET OF WEIGHTS

Weights are also used to calibrate and/or check the accuracy of other weighing instruments.

SPATULA

It is use to scrape away samples of biological materials, or chemical precipitates and residues.

TEST TUBE BRUSH

A test tube brush is used to clean out the bottom of a test tube.

TRIPOD

This lab equipment is used to support and hold various flasks, beakers and other glass ware when not in use and also during experiments.

PIPETTE

It is a laboratory tool commonly used to transport a measured volume of liquid, often as a media dispenser

OSTWALD PIPETTE

A special pipette used in measuring viscous fluid such as whole blood.

PASTEUR PIPETTE

plastic or glass pipettes used to transfer small amounts of liquids, but are not graduated or calibrated for any particular volume.

PETRI DISH

is a shallow cylindrical glass lidded dish that is typically used to culture microorganisms.

ROUND BOTTOM FLASK

is used for reactions, distillations and collection.

AUTOCLAVE

is used to sterilise solid and liquid media for microbial cultures

LABORATORY OVEN

Used in drying or getting the moisture content

HEATING MANTLE

used to apply heat to containers, as an alternative to other forms of heated bath.
