Level 4 Pipette Calibration & Repair

AS-FOUND AND AS-LEFT PERFORMANCE ANALYSIS

Six Levels Service Guide | Level 1 | Level 2 | Level 3 | Level 4 | Level 5 | Level 6 | Service at a Glance


Level 4 Service is used by laboratories operating in a regulated environment. These labs are typically involved in clinical trials, forensics or pharmaceutical research, QA studies, or Quality Control and manufacturing, and require complete documentation for both the As-Found and As-Left status of each pipette. Level 4 is used by many labs that require certification but not measurement uncertainty for each instrument's calibration event.

As part of our Level 4 Service:
Parts are priced competitively at or below retail price and are subject to change.
Calibrate, Inc. will abide by any and all safety requirements of your company.
Calibrate, Inc. guarantees messages will be answered with a return call from a Calibrate, Inc. Service Representative within 48 hours of an inquiry.
Warranty declaration for calibration, labor, and parts.


1. Pipette Identification:

Calibration reports are indexed by the serial number of the pipette, and/or by any additional identification codes (such as property tag numbers, or asset numbers) or by identifying markings found on the pipettes (such as initials or lab name). The next date for recommended service will be based on a semi-annual maintenance schedule unless otherwise specified by the client.

2. Preventative Maintenance and Accuracy Verification for GMP/GLP Applications:

  • As-Found data collected prior to any inspection, cleaning, and disassembly of the instrument.
  • Complete disassembly (as applicable), inspection, and cleaning of the instrument.
  • Replacement of Teflon seal and o-ring or grease, if the instrument requires a seal, and as recommended by the manufacturer.
  • Calibration of instrument to Calibrate, Inc.'s SOP 125–Level 4 specifications or to your unique calibration needs as defined by the contract review process.
  • Sticker affixed to pipette with information such as date of service and service provider, the serial number of the instrument, technician's initials, date of calibration, and next calibration due by month, day and year. Specific details concerning the information to be presented on the calibration label are determined with the customer during the contract review process.
  • Optional Out of Service Report can be prepared for each instrument that cannot be repaired or is taken out of service.
  • Toll-Free Service Center telephone number and easy-to-use Service Ordering via our website.
  • All equipment used for calibration is NIST traceable (copies of all NIST traceable Calibration Certificates are available upon request).
  • As-Found and As-Left inaccuracy and imprecision data is provided for each pipette based upon the number of samples and volumes agreed upon during the contract review process. Calibrate, Inc. has a variety of validated templates designed to meet your verification needs.

    3. Calibration Certificate:

    Calibrate, Inc. provides its Level 4 customers with a Calibration Certificate. This certificate provides valuable information concerning the pipette including: serial number; size; manufacturer; location; environmental conditions; and all the NIST traceability information concerning the Calibrate, Inc. Measurement and Test Equipment used in pipette calibration. Detailed As-Found and As-Left Calibration Data are provided for each pipette serviced. Reference Calibrate, Inc.'s SOP 125-4.

    4. Failure Report:

    If an instrument fails the As-Found data check, the failure is noted on the Calibration Certificate for that pipette, under As-Found Data. In addition, Calibrate, Inc. Representatives notify the end user of the failure in person or via the phone.

    If a pipette cannot be repaired and/or fails to meet the required tolerances, the instrument is tagged as failed or out of service. The end user must determine the disposition of the instrument. As part of the Level 4 Service, Calibrate, Inc. will be happy to complete an Out of Service report for each pipette that fails or cannot be repaired, for a small additional fee.

    5. Measurement and Test Equipment Verification and Traceability:

    All Measurement and Test Equipment is calibrated by accredited third party vendors of calibration, and copies of NIST (SI) traceable calibration certificates are available upon request.

  • The balance is allowed to equilibrate to the customer's location, and then its performance is verified prior to use. (Reference Calibrate Inc.'s SOP 181.)
  • Only Class I NIST (SI) traceable weights, NIST (SI) traceable hygrometers, and NIST (SI) traceable Delta Range balances are used.

    6. Environmental Conditions :

  • Environmental conditions present in the customer's lab are entered into the Calibrate, Inc. proprietary software.
  • The program then calculates the air density, liquid density, and the Z factor from the values of barometric pressure, temperature, and relative humidity.
  • The Z factor is used to calculate the weight to volume conversion.
  • The inaccuracy and imprecision data is calculated from the volume values.
