  2. What‘s a chemical laboratory? • a place for special researches • different kinds of laboratories (analytical, physicochemical, organic, inorganic, etc.) • necessary equipment • safety instructions must be kept there

  3. Alchemist laboratory - basic equipment - metal shears - filtering vessel - casting mould - vessel for separating oils lighter than water - crystallising dish - vessel for separating oils heavier than water - glass funnel vessel [vesәl] nádoba shears [šiәz] velké nůžky, kleště casting mould [ka:stiŋ mәuld] licí forma funnel [fanl] nálevka

  7. Modern laboratory - equipment • from porcelain, plastic and metal material:mortar and pestle, Buchner funnel, crucible, tong, spoon • glassware: pipette,beakers,flasks,burets, funnels, watch glass, test tube… • chemicals buret [bjuə’ret ] byreta flask [fla:sk] baňka funnel [fanl] nálevka pipette [pi’pet] pipeta

  8. Modern laboratory - equipment • Sophisticated laboratory devices: NMR and massspectrometers UV-VIS spectrophotometers chromatographs Analytical balance

  9. What we have to do... • to prepare for every laboratory session • to work quickly but correctly • to calculate and work up results of measurements • our results write down a report …to get credits

  10. Do you conform to the safety rules? • Wear safety clothes (shroud) and gloves if it’s necesary! • Use glasses or a security shield! • Respect all instructions! or…
