Description
Centrifuge tube with conical bottom, 9 ml is a laboratory glassware item intended for centrifugation and sample processing. It features an outer diameter of 16 mm and a height of 100 mm, providing a nominal volume of 9 ml. The tube is equipped with a GL 14 thread and screw cap that enables secure closure. Made from borosilicate glass 3.3, this centrifuge tube from manufacturer Rettberg is designed for laboratory applications requiring a conical-bottom format. Supplied as one piece, the tube is practical for small-volume sample handling and separation steps. The combination of the GL 14 screw closure and the conical bottom facilitates pellet formation and recovery after centrifugation. Dimensions of 16 mm outer diameter and 100 mm height align with common small-tube laboratory equipment. Research and analytical laboratories can use this glass centrifuge tube in protocols that call for defined thread size and compact conical geometry. The borosilicate glass 3.3 material is specified for consistent performance in routine laboratory glassware use.
This article is part of Centrifuge tubes (conical), in Tubes & vials.

Questions about Centrifuge tube, conical bottom, 9 ml, o-Ø 16 mm, height 100 mm,
What is this article?
Centrifuge tube, conical bottom, 9 ml, o-Ø 16 mm, height 100 mm, is the article on this page. Luminix Health distributes Rettberg for laboratory use. It sits in Centrifuge tubes (conical), inside Tubes & vials, in Labware.
A centrifuge tube is conical so a pellet collects at the tip, and it is rated for a relative centrifugal force. A 15 mL tube and a 50 mL tube are different rotors. Polypropylene is the ordinary plastic. The cap has to survive the same force as the tube.
A tube holds a small sample upright. A test tube is the open glass or plastic cylinder. A centrifuge tube is conical so a pellet forms at the tip, and it is rated for a centrifugal force the rotor will actually reach. A vial is a small closed bottle, often for a sample that will sit in an instrument. NMR tubes are a special case: the glass has to be uniform or the spectrum is the tube, not the sample. Laboratory ware is listed under ISO laboratory glassware.
