UKAS Accreditation for Automated Plate Handling Robots

The United Kingdom Accreditation Service (UKAS) has accredited the automated plate handling robots at the International Laboratory Services (ILS) new food microbiology testing laboratory in Derby, UK. ILS now has 3 automated plate inoculating robots and 1 automated plate spreading robot that are all UKAS accredited and are now available to process customer’s samples. The four machines were designed, produced and installed by AAA Lab Equipment.

The advantage of these robots over laboratories that use manual plating is:

  • Plate production is to a uniform standard
  • There is consistent control of media and the spread of the inoculums on the plate
  • Human error is minimised as the robot directs the operator on the inoculation dilution.

When a sample is booked in to the Laboratory Information Management System (LIMS) with the assigned testing, the information is fed through to the robot which:

  • Selects the appropriate agar
  • Takes a petri dish
  • Removes the petri dish lid
  • Pours the agar into the petri dish
  • Instructs the analyst on what sample dilution to inoculate the plate with
  • Replaces the lid
  • Mixes the inoculums with the agar in a consistent manner
  • Cools the plate
  • Barcodes it with the sample and test information
  • Then stacks them ready for incubation.

This happens in a HEPA filtered atmosphere which significantly reduce any potential environmental contamination.

This will give ILS’s microbiological food testing service greater precision and repeatability to give their customers results of a more consistent quality, with better control of media than manual plating laboratories. Enabling ILS to provide a service of the highest scientific standards and remain at the forefront of contract laboratory testing.
