Calibration Services


VWR, the preferred vendor for laboratory supplies, offers calibration and cleaning for laboratory equipment.

  • Pipettes
  • Temperature instruments
  • Timers and stopwatches
  • Humidity and pressure instruments

Calibration and cleaning is performed on a bi-monthly basis. Please contact VWR representative Amy Van Arsdale at 847-274-9152 or for more information.

If you have an item that is too large to drop off, stop by the stockroom and pick up a repair form. A repairperson will schedule an appointment to clean and calibrate it in your lab.


Mettler-Toledo holds quarterly Balance, Scale, and pH Meter Calibration Weeks. Visit the Lab News page for more information.

If your lab has balances, scales, or pH meters, they can be maintained through Mettler-Toledo's calibration program.

Program Services:

  • Annual or Bi-Annual Preventative Maintenance
    Preventative maintenance for balances, scales, or pH meters includes cleaning, calibration, adjustments, and minor repairs. Service is billed at $75/unit. Any additional parts required for non-routine repairs are discounted 20%. This work will be billed to your department/school chart string.
  • Emergency Calibration
    Emergencies due to circumstances that go beyond warranty and guaranteed work are billed at the Preventative Maintenance Service Program Rate of $150/hour (as well as $144/hr for travel time). This work will be billed by invoice directly to the department/school.

For annual or bi-annual preventative maintenance, labs will be billed to their department/school chart string. A purchase order is not necessary. If charging to a sponsored program, verify that account code 75450 is open.

For emergency calibration, invoices will be sent directly to the department/school.
