Laboratory Equipment

Centrifuges:

  • recommended speeds and loadings must not be exceeded;
  • tubes must be adequately robust and examined for defects before use;
  • loads must be balanced and tubes not overfilled;
  • hazardous materials must be centrifuged in capped or sealed tubes;
  • buckets, rotors, trunnions, cushions etc must be positioned correctly;
  • interlocks preventing lids being opened while the centrifuge is in motion must not be overridden;
  • centrifuges should be checked for signs of spillage after use;
  • spillages that are not dealt with correctly can lead to corrosion of rotors etc and their eventual failure;
  • rotors and other components should be inspected and maintained according to the manufacture’s recommendations; and
  • cellulose acetate and cellulose nitrate tubes must not be autoclaved (explosion risk) and their use should be avoided.

Glove boxes:

  • should be used either for storage of materials or for experiments;
  • should be checked for leaks;
  • should not contain sources of ignition (e.g. sparking electrical equipment) if used for flammable or explosive material; and
  • must incorporate devices to contain explosives/implosives if necessary.
