The chemistry lab is a place where the essence of matter can be explored. While some labs may have very specialised equipment (depending on research needs) such as high-pressure liquid chromatography and mass spectrometers, all chemistry labs will typically have a selection of equipment in common. This equipment must be serviced regularly, as well as properly cleaned and stored after each use.
The most important equipment in the chemistry laboratory is safety equipment. Emergency showers and eye wash stations, fume hoods, fire suppression equipment, safety glasses and lab coats provide a measure of protection against the potentially harmful effects of chemicals and reactions in the laboratory. Training in the use of safety equipment can lead to quick control of emergency situations.
Mass, Volume and pH
Accurate measurement of the mass of chemicals requires a calibrated electronic balance, though some labs may substitute a triple-beam balance when high precision is not required. Measuring the volume of reactants, products and catalysts often necessitates the use of graduated cylinders and pipettes. PH meters should be calibrated prior to each use for the pH range to be measured accurately.
The glassware in a chemistry lab includes beakers (for holding liquids), Florence flasks (round-bottomed flasks), volumetric flasks (long-necked flasks), Erlenmeyer flasks (flasks with increasing circumference going from neck to bottom), filter flasks (for filtration) and a variety of test tubes used for various experiments.
When assembled, a ring stand provides a framework with which to hold equipment during experiments. The components of a ring stand include a ring stand, ring stand clamp, support ring, utility clamp and wire gauze.
A variety of additional equipment is commonplace in chemistry labs, including Bunsen burners, strikers, mortar and pestle, clay triangles, watch glasses, crucibles, crucible tongs, chemical spoon, stirring rods, filter funnels and a variety of stoppers.
