Features: plastic test tubes for laboratory tests round bottom with screw caps on the top ideal for samples, food colorings, craft use, etc. These were manufactured for use as centrifuge tubes and hence are leak proof. The non wetting interior surface eliminates concave menisci, providing more accurate measurements switching from glass cylinders to globe's plastic equivalents will greatly reduce breakage and the potential for injury chemically resistant to most acids, bases and many common solvents .
