    Regarding pipette certificates, will "as found" data with no adjustment suffice for a pipette calibration for ISO/IEC 17025 in a lab that's accredited with the following:
    • 1. ISO 17025 only?
    • 2. ISO 8655 only?
    Cheers everyone,

    Hello, welcome the forum!

    with respect to your question, is this in regards to a calibration company performing calibrations for others, or doing it internally?

    Hi Brad,

    Appreciate the response. Yes that's correct, for a third party company that is performing calibrations for us. We are seeking the 17025 accreditation and two calibration labs we're looking at as potential vendors hold accreditation status for points 1 & 2. To be cost effective, we've chosen the basic pipette service for each which provides "as found" data with no adjustment and includes uncertainty data.

    Ah gotcha. Well technically you don’t have to get them adjusted for optimal accuracy. But.... if pipettes are ‘t cleaned, maintained, lubed, etc., they will accumulate error.

    I recommend reviewing and tracking the amount of error found when they are returned. If they start trending up, you will need to spend the money for adjustment, or they will start failing.

    I venture to say I could pay for five single channel maintenance activities for what one deviation/investigation would cost.
