It has been disassembled, inspected, fully cleaned, and calibrated by a trained technician. The seal and O-Ring have been replaced as per manufacturer's recommendation. The internal components are in excellent condition  and the pipette draws evenly and seals well. The aspiration stroke is smooth and responsive. While in excellent cosmetic condition, the pipette may show signs of light wear or marking under close inspection. This does not have an affect on performance or  calibration.

 

This pipette has been calibrated and found to be within manufacturer's specification. While it is suitable for general research use, users should have the pipette inspected and certified by their own independent  technician prior to performing GLP/GMP work or handling precious samples. If you have any technical questions or concerns, please do not hesitate to let me know.
