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.

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
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 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 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
NVLAP* Pipette Calibration Certificates (view samples of gravimetric
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

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
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
- Performed under
the same strict conditions as the Level 1 Pipette Calibration
- 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
- Performed under the same strict conditions as the Level 1 Pipette
