Instruction to follow sample collection for Water (Water/Waste water) Testing

For testing of Chemical Parameters
  • Specially, Collect the water/wastewater sample in Cleaned and dried bottle.
  • If you want to test oil and grease, Collect Waste water sample in cleaned and dried marked Glass bottle.
  • The Required Sample Volume – 1 Liters or more for Water/Waste water & 500ml(marked) for oil and grease.
  • Completely fill the bottle with water/wastewater and close it tightly without any air bubbles interference.
  • Check the pH & temperature at site.
  • Hand over the sample to the Laboratory within 24 or less hours in a cool(Ice) box (4oC – 6oC).
  • Testing parameters, units and test methods are following. (Parameters in italic do not cover accreditation)

For Microbiological testing

  • Sterilized bottle provided by our laboratory (250ml bottle).
  • Fill the sterilized bottle leaving small space with the sample and close with the lid.
  • Hand over the sample to the Laboratory within 24 or less hours in a cool(Ice) box (4oC – 6oC).
  • Testing parameters, units and test methods are following. (Parameters in italic do not cover
  • accreditation)

Testing can be done

  • Testing for chemical parameters in water/wastewater can be done by our laboratory. Testing for Microbiological parameters in drinking water can be done by CEA or SLAB Accreditation other laboratory.
  • According to your requirement selected parameters can be done and the charges for that should take from laboratory.

Collecting your report

  • Hand over the sample to the laboratory with the Full payment from Cash or Checks.
    Fill the information in the provided document.
  • The test report can be issued within working 8 or 10 days.
  • The test reports can be posted or can be collect direct from the laboratory before 2.30 pm in weekdays.
