MICROCENTRIFUGE TUBES: DESIGNED SPECIFICALLY TO FIT INTO LOW VOLUME MICROCENTRIFUGE DEVICES COMMONLY USED IN LABORATORIES. DESIGNED TO WITHSTAND GRAVITATIONAL FORCES UP TO 20000G; HIGH FORCES LIKE THESE ARE REQUIRED TO CONCENTRATE MICROGRAM BIOLOGICAL SAMPLES SUCH AS DNA. WALL THICKNESS IS REQUIRED TO BE HIGHLY UNIFORM IN ORDER TO DISTRIBUTE FORCES EVENLY. PRECISION MOULDED IN RESEARCH GRADE POLYPROPYLENE.
