Do you offer class A plastic graduated cylinders?

We do not offer plastic graduated cylinders with Class A accuracy. It is very difficult to reach Class A accuracy with plastic, which is why they are almost always glass.

What are your ASTM certified labware offerings?

Class B graduated cylinders meet ASTM E1272 and ISO 6706. Double-scale pharmaceutical graduates meet ASTM E1094. Class B volumetric flasks meet ASTM E288 and ISO 384. Burets meet ASTM E287. It is important to note that after autoclaving, even certified products may no longer be as accurate.
