Column Chromatography Apparatus Setup – Hints – 360° Interactive Exercise

That is not quite right. Have another go.

Look through the five flash column chromatography apparatus scenes by clicking on the A-E buttons in the image below. Try to identify any hazards/errors within the five scenes.

When you spot the flash column chromatography apparatus with the fewest errors, click on the button to the right to see if you are correct.

Additional activity: Make a list of good and poor practice within the five flash column chromatography apparatus scenes above. When you are presented with the answers, you can self-evaluate your hazard perception skills.

Disclaimer: We have deliberately introduced health and safety issues into these flash column chromatography apparatus scenes for educational purposes.  We do not condone bad lab practice, but allowing learners to see such scenarios can help develop hazard perception skills and a general appreciation of health and safety. We have not highlighted all hazards in these exercises. Best practice may differ in your institution so please discuss this with a local instructor before setting up any apparatus.

Which scenario has the fewest errors? There are hints below to help.

Have you considered the following :

  • – How is the column clamped?
  • – Should a clip be used?
  • – Is there solvent in the column?
  • – Are gloves being worn?
  • – Should the tap at the base of the column be open?

Note: Not all aspects may be visible in each image.
