Description
Test tubes, borosilicate glass 3.3, heavy-wall with beaded rim, approximately 180 mm long and 18 mm in diameter, function as versatile laboratory vessels for reagents and samples. Fabricated from borosilicate glass 3.3, they deliver chemical durability reinforced by the heavy-wall construction. The beaded rim enables secure capping and neat pouring during standard operations. Delivered in packs of 100 pieces from manufacturer Hecht, these tubes support everyday laboratory workflows. They are well suited to holding solutions, conducting simple reactions and temporary sample storage, and they integrate with common racks and heating equipment. The extended length supplies additional working volume while remaining compatible with typical stoppers. Research, teaching and quality-control environments employ this glassware for general-purpose needs. Robust build quality handles the mechanical stresses of mixing, heating and transport where borosilicate glass 3.3 is the material of choice.
This article is part of Test tubes, in Tubes & vials.

Questions about Test tubes, borosilicate glass 3.3, heavy wall with rim mm Ø ca. 180 x18
What is this article?
Test tubes, borosilicate glass 3.3, heavy wall with rim mm Ø ca. 180 x18 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.
