Calibrate good times

摘要

Laboratories often assume that their liquid handling instruments, from pipettes to automated liquid handlers, are operating within specifications. However, because data integrity for applications, from drug discovery to molecular diagnostics, relies on accurate and precise liquid delivery, this is a risky assumption with potentially high failure costs. Liquid-delivery instrumentation can be verified using gravimetry which measures liquid weight on analytical balances, This method is adequate for larger volumes such as millilitre quantities, but is not as effective at lower volumes such as microliter and nanolitre quantities. However, laboratories are increasingly working with smaller anc smaller volumes and this trend is expected to continue.
