This 25ml acrylic burette is graduated and screen printed in black to Class B accuracy. Transparent and break resistant, it is suitable for use in education, research or industrial laboratories--especially where breakages often occur. This series is unaffected by most dilute aqueous solutions (except ammonia and HF), but unsuitable for ethanol or organic solvents. Lengths and internal dimensions can vary, as all are individually calibrated. Capacity: 25ml. Per each. Dynalon® #: 564715-0025.
