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.
Class B cylinders are certified to meet ASTM accuracy and precision standards. Economy cylinders bear no specific accuracy or precision certification. It is important to note that after autoclaving, even certified products may no longer be as accurate.
