Description
Centrifuge tubes PP 15 ml 18 x 118 mm graduated are transparent polypropylene centrifuge tubes with a conical bottom and graduation marks for laboratory centrifugation. Each tube measures 18 x 118 mm and holds 15 ml, offering a standard format for sample handling before, during and after spinning. The clear PP body allows visual checking of contents and fill level, while the conical base supports collection of sediments after centrifugation. Graduation on the wall assists volume reading when preparing or transferring samples. These tubes from manufacturer Witeg are autoclavable up to 120 °C within the stated temperature limit. Supplied in packs of 100 pieces, they suit laboratories that need a ready stock of graduated conical plastic tubes. The transparent, graduated design makes them practical everyday consumables for routine centrifugation workflows. Pack net weight is 0,518 kg according to the specifications. They belong to the centrifuge tube product group used across research and analytical laboratories for spinning and short-term sample holding.

Questions about Centrifuge tube PP 15ml 18x118mm graduated
What is this article?
Centrifuge tube PP 15ml 18x118mm graduated is the article on this page. Luminix Health distributes Witeg 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.
