Are the graduations on your labware molded on the inside, outside, or simply screen printed?

None of the graduations are molded on the interior. They would be very difficult to mold in that way, and would interfere with the accuracy. Exterior molding also allows for a better grip on the item. However, it does differ by product, specifically:

  • Graduated cylinders: All models have molded graduations, some have screened overprint. Graduated pitchers: All models, with the exception of the nesting models, have molded graduations. Some have screened overprint. Nesting models have printed graduations.
  • Beakers and Erlenmyer flasks: All models have screen printed graduations.
  • Volumetric flasks: All models have a scored graduation, with coloring added.
