Description
Blank reagent tubes for KJD10 are laboratory consumables intended for blank and control runs in Kjeldahl-related digestion workflows on the KJD10 platform. Supplied as a pack of 20 pieces, they support method blanks, reagent blanks and parallel control digestions where matched tube geometry is needed for consistent heating and handling. These tubes come from manufacturer Labbox and fit laboratories that operate KJD10 digestion setups and require dedicated blank vessels alongside sample tubes and catalyst tablets. Net weight of the pack is 0,800 kg, with the same gross weight stated for the unit. Product type is listed as LBG, with country of origin China. In nitrogen determination practice, blank tubes help quantify background contribution from reagents and handling so that sample results can be corrected appropriately. Use them as part of a complete Kjeldahl preparation set when standardised blank determinations are required for quality control, method validation or routine series work in food, feed, environmental or general analytical laboratories.

Questions about Sealing tubes, Kjeldahl for KJD10, 20 pcs
What is this article?
Sealing tubes, Kjeldahl for KJD10, 20 pcs is the article on this page. Luminix Health distributes Labbox for laboratory use. It sits in Tubes à essai, inside Tubes & flacons, in Matériel de laboratoire.
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.
