After its first use, pipette and liquid handling devices begin to fall out of factory calibration.  For spring operated instruments, the process of aspirating and blow-out cause spring deformation and spring hysteresis.  When this occurs, the volume is altered and must be recalibrated. Dropping pipettes, misuse and general laboratory practices can also effect the pipettes calibration.  Old shafts, overused micrometers and faulty tips holders can cause unsatisfactory performance of the pipette or liquid handler.  The effects of altered volumes can invalidate studies, waste funding and be subjected to nonconformity issues. Hospitals, pharmaceutical companies and research institutes who follow GMP, GLP, FDA and ISO must ensure they have properly operating equipment.  Utilizing calibration tools, 5 place balances, and certified parts, ECS will reset the pipettes and liquid handlers to factory settings. As an ISO accredited service, ECS is one of the few companies capable of guaranteeing services that have been vetted by a third-party organization. This ensures we are following proper procedures and keeping our clients information safe.  Guarantee you instruments are accurate and functioning correctly with one simple step: Pipette Calibration Services.
