NVLAP Accredited Pipette Calibration -
0.1 µl to 10 ml with capabilities up to 100 ml.

Troemner’s Pipette Calibration Laboratory was the first NVLAP* accredited laboratory for pipettes in the United States. Troemner offers a complete calibration and repair service for most brands of pipettes, repeaters and burettes.

Facility and Environment

Troemner's state-of-the-art Pipette Calibration Laboratory meets or exceeds the requirements listed in internationally recognized standards. This laboratory was carefully designed and constructed to reduce the effects of vibrations and to strictly control and monitor the environment. Temperature in the laboratory is measured to ± 0.01 degree C and controlled to within 0.2 degree C, with no more than a 0.2 degree C change per hour. Humidity is measured to ± 2% with no more than a 5% change per hour. Barometric pressure is measured to 0.01 mm Hg.

 
Equipment

Troemner has invested in the most advanced instrumentation including gravimetric and spectrophotometric equipment for calibrations of pipettes. Gravimetric pipette calibrations are performed using six high precision balances and mass comparators; some with resolution as low as 1 µg. Troemner also uses humidity traps and other methods to assure accurate gravimetric calibrations. Due to the direct relationship between weight and volume, the Troemner reputation for weighing accuracy is fully utilized in the pipette calibration process to achieve low measurement uncertainties. Spectrophotometric calibrations are performed using photospectrometry, whereby refractive index is proportional to volume. Both techniques assure that only the highest standards are met for complete reliability of pipette calibrations.

 
Staff

Troemner's staff of metrologists and technicians possesses a high level of expertise in performing superior pipette calibrations, adjustments and repairs. Troemner’s metrology staff and calibration technicians also have training from several pipette manufacturers.

 
Processes

Troemner’s pipette calibrations are comprehensive and include details such as making sure that every channel of a multi-channel pipette is fully tested and calibrated. Troemner performs vacuum and leak tests, cleans every pipette, greases the piston, and inspects seals and "O" rings to assure performance accuracy after the calibration. Calibration procedures also include full service and parts availability for all types and brands of pipettes. Free repair estimates are provided.

 
Pipette Calibration Certificates

Troemner’s NVLAP* Pipette Calibration Certificates (view samples of gravimetric and photometric certificates) are designed to meet stringent regulatory and audit requirements including all ISO (including ISO/IEC 17025), FDA, GMP, GLP, DOD, NCCLS, CLIA, ANSI/NCSL Z540-1, and nuclear requirements. The NIST-administered National Voluntary Laboratory Accreditation Program (NVLAP Lab Code 105013-0) approves all procedures for this detailed certificate.

Troemner offers various levels of Pipette Calibration Service.

Troemner offers three standard pipette calibration services. We can also customize calibrations to meet your particular requirements. Below is a comparison of the various standard services available from Troemner.

 
Level 1, Level 1A Pipette Calibration Service – designed to meet all of your stringent requirements including: GLP, GMP, FDA, ISO, NCCLS, CAP and CLIA.

• The most comprehensive NVLAP* accredited repair, calibration and certificate service available.
• Level 1 - a 10-10-10 testing structure, utilizing 10 measurements at three different volumes for a total of 60 measurements. Included is the "As Found" and "As Left" data.
• Level 1A - a 4-4-4 "As Found" testing structure utilizing 4 measurements at 3 different volumes and a 10-10-10 "As Left" testing structure utilizing 10 measurements at 3 different volumes for a total of 42 measurements.

Level 2, Level 2A Pipette Calibration Service – designed for companies that may not require the extensive measurements and pipette calibration data provided by the Level 1 Pipette Calibration Certificate.

• Performed under the same strict conditions as the Level 1 Pipette Calibration Service.
• Level 2 - a 4-4-4 testing structure utilizing 4 measurements at three different volumes for a total of 24 measurements. Included is the "As Found" and "As Left" data.
• Level 2A - a 4-4 testing structure utilizing 4 measurements at two different volumes for a total of 16 measurements. Included is the "As Found" and "As Left" data.

Level 3 Pipette Calibration Service – designed for companies who require third party validation of "as found" data only. This service includes:

• Visual inspection upon arrival for signs of damage and/or wear. If the pipette is determined to be inoperative or malfunctioning, the cost of the repair and any necessary parts will be determined and a Troemner representative will contact you for approval to either proceed or to return the unit in its "As Found" condition. Cost of repair and replacement parts is extra.
• Performed under the same strict conditions as the Level 1 Pipette Calibration Service.
