Description
Centrifuge tube with conical bottom, 9 ml, O.D. 16 mm, height 100 mm is a compact laboratory glass tube engineered for small-volume centrifugation. Made from borosilicate glass 3.3, it provides a nominal volume of 9 ml, an outer diameter of 16 mm and a height of 100 mm. The conical bottom concentrates sediments efficiently, facilitating clear separation and easy recovery of pellets. Equipped with a ground joint sleeve NS 12,5/14 and a hollow stopper, the tube maintains a secure closure during operation and storage. This centrifuge tube from manufacturer Rettberg delivers the chemical durability and thermal stability expected of borosilicate glass 3.3, rendering it appropriate for analytical, biochemical and clinical workflows. The standardised joint ensures compatibility with common laboratory fittings, while the hollow stopper allows convenient handling. Offered as a single piece, the tube is well suited to protocols requiring precise small-volume separations where optical clarity and material inertness are essential. Its sturdy construction supports repeated cleaning and sterilisation cycles typical of modern laboratory practice.

Questions about Centrifuge tube, conical bottom, 9 ml, o-Ø 16 mm, height 100 mm, with
What is this article?
Centrifuge tube, conical bottom, 9 ml, o-Ø 16 mm, height 100 mm, with 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.
