altSarstedt (Newton, NC) has introduced a 13 × 75 mm configuration to its existing line of false-bottom screw cap aliquot tubes. False-bottom tubes feature an elevated conical base that lifts serum/plasma yields to a more optiumum height for automated analysis. The new option has a small 2.5 mL filling volume, a rounded skirt for accommodation in analyzer racks, and is made from polypropylene with molded-in graduations.
