Metrova™ for pipette calibration
Pipette calibration,
graded as you weigh.
Gravimetric calibration to ISO 8655 on the tablet: the weighings go in, the Z factor and the errors are worked out as they do, and the certificate and sticker print from the record. Your customers find every certificate and due date in their own portal.
The methodGravimetric, to ISO 8655: ten weighings at each test volume.
The limitsISO 8655-2, the manufacturer's, or your customer's own, named on the certificate.
The pipettesSingle-channel and multichannel, fixed and variable volume.
The priceIts own department, and free when you run Calibration too.
On the bench
- Scan the pipette's tag and its history opens. One tap starts today's certificate from the last one, carrying its volume range, its channels and whose limits it is judged against, and never last visit's weighings or room conditions.
- The test volumes come from the pipette itself: its nominal volume, half of it, and a tenth of it, or its minimum if that is higher.
- An as-found check before anything is adjusted, then ten weighings at each volume as calibrated. The two passes are kept apart, so a mean never mixes a pipette before its adjustment with the same pipette after it.
- Record the water temperature and the barometric pressure, and the Z factor is worked out from them; the masses become volumes through it.
Graded as you weigh
- Each volume's systematic error (is it accurate?) and random error (is it repeatable?) are worked out as the weighings go in.
- Each is graded against ISO 8655-2, or against the manufacturer's limits or your customer's own when that is what the job calls for. The certificate names which limits it was judged against.
- The service done on the pipette is ticked off on its certificate: seals, O-rings, pistons, shafts, filters, preventive maintenance.
After the bench
- The certificate is approved by someone other than the technician, and the sticker prints from the record with a QR code that opens the pipette.
- Every certificate sets the pipette's next due date, so your recall list and the reminder emails build themselves.
- Your customer sees each pipette's certificates and due dates in their portal, and asks for a correction there if something is wrong, on the record.
Being built: a Pipettes department of its own
Pipette calibration runs today inside Calibration. A Pipettes department of its own, with its own page and list beside Calibration, is being built now. Tell us how your shop runs pipettes and it will be built around that too.
