Do you offer onsite pipette calibration?

No, we do not offer any onsite services due to limited control of environmental conditions. The American Association for Laboratory Accreditation (A2LA), published a policy in 2012 stating that higher measurement uncertainties are expected from onsite calibration. View that policy here: A2LA Policy P104

All of our calibration service and pipette repairs are performed in an environmentally controlled facility that complies with ISO 17025 standards for temperature, humidity, etc.
