The United Kingdom Accreditation Service (UKAS) is the sole accreditation body recognised by government to assess, against internationally recognised standards, laboratories that provide test and calibration services. UKAS combines a depth of technical knowledge and expertise built up over many years with scientific and technical specialists operating across the entire test and calibration spectrum, from forensics to food safety. Accreditation by UKAS demonstrates the competence, impartiality and performance capability of laboratories.
UKAS ISO 17025 accredited laboratories have:
- Competent and trained staff
- Properly maintained and calibrated instruments
- Internal and external quality control
- International recognition
Being ISO 17025 accredited for pipette calibration means that we can provide our clients with an assurance of our laboratory procedures and the validity and quality of our results.
- Test work will be conducted by valid, recognised, technical methods suitable for the purpose required and of established performance characteristics
- The work will be performed by properly qualified and trained staff
- The work will be carried out on equipment which is functioning properly and which is calibrated so as to provide traceability to international standards of measurement
- Data will be subject to quality control, both from the point of view of accuracy & precision, by means which have been approved by independent technical assessors
METTLER TOLEDO’s pipette service operates to these standards meaning that you will always benefit from these advantages. The same certified equipment, trained personnel and procedures are used whether you use the full UKAS service level and certification or one of our regular service options.
Whether or not your own laboratory is UKAS accredited, by using METTLER TOLDEO for your pipette service your minimise risk.
FAQs
METTLER TOLEDO Certification
1. What does UKAS Accreditation mean to me?
Based on rigorous documentation, extensive training, and long-term proficiency testing, METTLER TOLEDO’s Pipette Service division has achieved the highest level of calibration competency and data integrity when using the gravimetric method and now provides a single point for servicing of all major brands of pipettes to this level.
When you choose UKAS calibration you will receive additional information on your Calibration Certificate including statement of measurement uncertainty per volume setting. Whether or not you choose this option, METTLER TOLEDO’s Pipette Service complies with all quality standards as set forth by ISO guidelines and UKAS interpretation, assuring you of the highest level of calibration competency and traceability.
Isn’t it comforting to know that UKAS auditors have ensured the highest calibration standards are being met, so you can trust your service provider.
2. What is ISO 8655?
ISO/EN8655 is an international standard for the volumetric calibration of Piston Operated Volumetric Apparatus (POVA). The standard, which is in seven parts has become an ISO standard and a European Norm and all European National Standards such as BS6018, BS7532 and DIN 12 650 have been superseded in its favour.
Calibration methods are detailed in the standard and the gravimetric test is the reference method. Maximum errors for trueness (Inaccuracy) and precision (CV%) are listed for all types of POVA device.
The standard states "Apparatus shall be calibrated with noted tips. (A pipette calibrated with a specific tip shall only be deemed within calibration with that tip)".
ISO 8655 recognises pipettes, tips and service as a complete system.
