1 Laboratory Equipment The figure was adopted from (Dec 2006)http://vip.busytrade.com/huaou

2 volumetric cylinders watch glasses beakers The figures were adopted from z (Dec 2006)http://vip.busytrade.com/huaou

3 volumetric flasks The figures were adopted from and (Dec 2006)http://vip.busytrade.com/huaou

4 measuring of a precise volume „meniscus“ = a concave upper surface that forms on a liquid in a tube as a result of surface tension

5 filling the volumetric flask

6 glass pipettes filling the pipette using the pipette pump pipette pump

7 insertion of the pipette into the pipette pump: carefully, but tightly

8 meassuring of a precise volume of 5 mL  4,49 mL  4,85 mL 5,0 mL The figures are from (Dec 2006)http://www.uwplatt.edu/chemep/chem/chemscape/labdocs/catofp/measurea/volume/pipet/page.htm

9 measuring out a precise volume by the doser doser test tubes holder

10 doser storage bottle dosing plunger wheel for volume adjustment

11 titrimetric flask burette „titration“

12 burette burette filler graduated tube storage bottle dosing stopcock

13 filling the burette using the burette

14 automatic pipette

15 plastic tip pipetting button emptying filling The figure was adopted from the CD-ROM: Encyklopedie laboratorní medicíny pro klinickou praxi 5. Kolektiv autorů, ed. A. Jabor, M. Zámečník, SEKK s r.o., Pardubice, Katedra klinické biochemie IPVZ Praha, 2005, hypertext. ISBN

16 the pipette can be used solely with a plastic tip

17 automatic pipette for the volume range: 10 – 100  l yellow tip is destined for „yellow pipette“

18 automatic pipette for the volume range: 10 – 100  l yellow tip is destined for „yellow pipette“

19 automatic pipette for the volume range: 100 – 1000  l blue tip is destined for „blue pipette“

20 automatic pipette for the volume range: 100 – 1000  l blue tip is destined for „blue pipette“

21 volume adjustment of the automatic pipette Never adjust volume out of the allowed range! turn slowly

22 stendby 1 st position 2 nd position holding the pipette

23 filling emptying Pipetting step by step 1 st stendby 1 st 2 nd The figure is from: Encyklopedie laboratorní medicíny pro klinickou praxi 5. Kolektiv autorů, ed. A. Jabor, M. Zámečník, SEKK s r.o., Pardubice, Katedra klinické biochemie IPVZ Praha, 2005, hypertext. ISBN

24 Removing of solution drops from the tip surface the drops can be removed only in a direction from up to down

25 stendby position 1 st position (= filling the pipette)

26 emptying the pipette (2 nd position)

27 tip ejector button

28 spectrophotometer

29 pH meter with an electrode immersed into buffer solution

30 chromatographic chamber with a thin layer inside (TLC chromatography)

31 fume cupboard chromatographic chambers

32 water bath (thermostat)

33 equipment for gel electrophoresis power suply (direct current) electrophoresis chamber applicator containers for staining and destaining gel
