PROCEDURE
FOR PIPETTE REPAIR AND CALIBRATION |
| 1.
Set-up
the analytical balance that is certified by an outside company.
Allow twenty to thirty minutes for the balance to acclimate.
Perform on-site calibration with Calibrated Ultra Class weight
traceable to NIST. |
| 2.
Highly purified distilled
water will be used maintaining a constant temperature of eighteen
to twenty-four degrees Celsius. |
| 3.
Each instrument is logged using
the manufacturer's serial number and/or the number the lab has
assigned, model and volume range. If there is no number, the
technician will etch a number on the handle of the instrument. |
| 4.
Check the instrument at two levels,
high and low, with at least three measurements at each level.
Each measurement is recorded. (Up to tem readings for an additional
fee, depending on your SOP requirements). |
| 5.
Disassemble the instrument and
check for: a.Corrosion of piston b.Seal
and/or o-ring wear c.Worn, broken or missing
components. |
| 6.
Combined results of Step #4 and
Step #5 determine if the instrument passes inspection. |
| 7.
If the instrument passes inspection,
a sticker with the date of calibration will be affixed and returned.
If the instrument does not pass inspection, it will be disassembled
and cleaned. Worn, broken or missing components will be replaced.
The instrument will then be calibrated at two levels, high and
low, with three or more readings at each level. A sticker with
the date of calibration and due date for the next calibration
will be affixed. |
| 8.
If the instrument is not repairable
or not cost effective to repair, it will receive an "Out
of Calibration" sticker and returned. |
| 9.
Copies of the calibration report
will be provided to the necessary departments for their records. |
| 10.
Our procedure meets GMP/GLP, FDA, ISO, CLIA and CAP
requirements for pipette calibration. |
