CLASS “A”

We call it the ‘CLASS “A” EXPERIENCE’, not only because we have one of the most reliable testing labs and state-of-art equipment settings, but more importantly because we give our clients a better business experience in Class “A” Glassware Items.

We have managed to achieve a “Win-Win” situation, both for our Calibration Labs and our Esteemed Clients, which enable us to offer Class “A” calibrated products at astoundingly reasonable rates.

Please contact us to know how we manage to do this, without compromising on quality.

Calibration Certifications:

  • Our ranges of Volumetric Products are available with Calibration Certificates. Our certificates confirm that the product has been tested for compliance to the appropriate standard.
  • Our Class “A” Glassware Range comes with Individual Calibration Certificate and an Individual Product Serial Number.
  • Each certificate includes details of the actual volume, uncertainty estimation for the calibration and the required tolerance for compliance
  • Graduated Pipettes, Cylinders and Burettes are calibrated at three separate points on the scale which is detailed on the certificate.
