Description
Test tubes "ELKA" with beaded rim are laboratory glassware items measuring approximately 100 mm in length by 12 mm in diameter. Fabricated from soda-lime glass, they serve as clear vessels for holding samples, reagents or reaction mixtures in scientific workflows. The distinctive beaded rim improves handling and stability when placing the tubes in racks or transferring contents. Supplied in packs of 100 pieces, these tubes support everyday needs in research, teaching and routine analysis. The soda-lime glass construction makes them suitable for a wide range of non-specialised laboratory applications. Available from manufacturer Hecht, the ELKA test tubes integrate into standard laboratory setups for chemistry, biology and medical diagnostics. Their approximate dimensions of 100 x 12 mm allow compatibility with conventional test-tube stands and holders. The open cylindrical form facilitates pipetting, observation and temporary specimen containment. Consistent sizing supports qualitative tests and sample preparation protocols. These beaded-rim tubes provide practical glassware for general laboratory requirements involving reaction tubes or sample tubes.

Questions about Test tubes ELKA, with rim mm Ø ca. 100 x 12
What is this article?
Test tubes ELKA, with rim mm Ø ca. 100 x 12 is the article on this page. Luminix Health distributes Hecht 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.
