TUBE DESIGNED SPECIFICALLY TO FIT INTO LOW VOLUME MICRO CENTRIFUGES, USED IN RESEARCH LABORATORIES. THE TUBE IS PRECISION MOULDED FROM RESEARCH GRADE INERT POLYPROPYLENE. IT IS ENGINEERED TO WITHSTAND FORCES UP TO 20,000 G, AS FORCES LIKE THESE ARE REQUIRED TO CONCENTRATE MICROGRAM BIOLOGICAL SAMPLES, SUCH AS DNA. THE TUBE HAS A HIGHLY UNIFORM WALL THICKNESS IN ORDER TO DISTRIBUTE THE CENTRIFUGAL FORCES EVENLY. THE TUBE IS FITTED WITH A LID.

CLASSIFICATION HAS BEEN DETERMINED IN ACCORDANCE WITH THE FOLLOWING: GENERAL INTERPRETATIVE RULES (GIR)S GIR 1 HAS BEEN USED TO CLASSIFY THIS PRODUCT BY THE TERMS OF HEADING 8421 - CENTRIFUGES, INCLUDING CENTRIFUGAL DRYERS; FILTERING OR PURIFYING MACHINERY AND APPARATUS, FOR LIQUIDS OR GASES GIR 6 HAS BEEN USED TO CLASSIFY THE GOODS TO SUBHEADING LEVEL 8421 91 - PARTS OF OF CENTRIFUGES, INCLUDING CENTRIFUGAL DRYERS ALSO CLASSIFIED IN ACCORDANCE WITH: NOTE 2(B) TO SECTION XVI HARMONIZED SYSTEM EXPLANATORY NOTES (HSEN) (I) TO HEADING 8421
