Description
VACUETTE® tube 4 ml FX sodium fluoride / potassium is a laboratory collection tube with a 4 ml fill volume and an FX additive based on sodium fluoride and potassium. The tube measures 13 x 75 mm and is fitted with a grey cap and a black ring; the tube itself is transparent, so the collected material can be viewed after filling. Grey cap and black ring colour coding help distinguish this FX sodium fluoride / potassium format from other tubes in the same size class. The 13 x 75 mm geometry is intended for routine laboratory handling, including placement in standard racks used for this diameter and length. This VACUETTE® tube from manufacturer Greiner Bio-One is laboratory material for sites that specify the FX sodium fluoride / potassium additive combination together with a 4 ml fill volume. Transparent walls support visual confirmation of fill. Choose this 4 ml FX tube when protocols require VACUETTE® 13 x 75 mm tubes with grey cap, black ring and sodium fluoride / potassium additive.

Questions about VACUETTE® tube 4 ml FX sodium fluoride / potassium
What is this article?
VACUETTE® tube 4 ml FX sodium fluoride / potassium is the article on this page. Luminix Health distributes Greiner Bio-One for laboratory use. It sits in Test tubes, inside Tubes & vials, in Labware.
A test tube is the open cylindrical vessel for a small liquid, in borosilicate glass or in plastic. Rimmed and rimless mouths differ. The size is diameter by length. It is not graduated for a result, and a glass tube that will be centrifuged has a force limit.
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.
