These superior-quality graduated cylinders are ideal for the safe and accurate measurement of all types of liquids. Cylinders offer a wide rim and a tapered pour spout for easy filling and pouring. The nonwetting interior surface eliminates concave menisci, providing more accurate measurements. The wide pentagonal shaped base provides stability and makes the cylinder roll-resistant. The heavy-duty plastic withstands repeated autoclaving. Switching from glass cylinders to Globe’s plastic equivalents will greatly reduce breakage and the potential for injury.
