Product Category Description: Microcentrifuge tubes are constructed of polypropylene copolymer (PPCO) and are graduated with white scales to enable easy volume calculations. Large numerals on the necks of the tubes and on the flanges permit easy volume calculation. Plastic tubes blend with most liquids and are suitable for use in microtorches. The conventional-capacity tubes are suitable for applications in which a large volume is required and a short conical neck is required. Conical-bottom tubes are supplied with clear blue frosted necks. The microtubes have a slightly longer neck to admit a lid when a lid is present. The microtubes are too easily crushed during centrifugation.
