- Feature single metric scale, PYREX stopper
These graduated cylinders are calibrated "to contain" and are useful as mixing cylinders. Each cylinder features the PYREX stopper. Graduations are in durable white enamel.
When taper sizes are given, the first number is the stopper diameter (mm) across the top; the second number is the stopper length (mm). If only one number is given, it indicates the stopper diameter (mm) across the top.
