Description
Test tubes made of soda-lime glass with a round bottom deliver dependable vessels for laboratory sample handling at a slightly larger working volume. Each tube offers a 9 ml capacity with dimensions of Ø 12 x H 100 mm, suited to general chemistry, teaching laboratories and routine analytical workflows that need extra headspace or volume. Soda-lime glass provides good clarity for visual checks while remaining practical as a high-use consumable. Supplied in packs of 500 pieces from manufacturer Marienfeld, the tubes support efficient restocking for multi-user labs and course practicals. Round-bottom geometry helps with mixing and gentle heating applications where even heat distribution is preferred. The total pack weight is 3,500 kg, appropriate for central laboratory stores. The 12 mm diameter and 100 mm height fit standard racks designed for this common format. These soda-lime glass test tubes are intended for research, quality-control and educational settings requiring everyday glassware for sample preparation, qualitative work and straightforward observation tasks.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Test tubes, soda-lime glass, round bottom, 9 ml, Ø 12 x H 100 mm, 500 unit(s)
What is this article?
Test tubes, soda-lime glass, round bottom, 9 ml, Ø 12 x H 100 mm, 500 unit(s) is the article on this page. Luminix Health distributes Marienfeld for laboratory use. It sits in Round-bottom flasks, inside Beakers & flasks, in Labware.
A round-bottom flask is the heating flask of a distillation or a reflux. The curved wall takes the heat, and the ground neck connects to a still head or a condenser. The joint size, not only the volume, has to match the rest of the set.
A beaker is an open working vessel: easy to pour, poor as a measure. An Erlenmeyer flask has a flat base and a conical wall so a liquid can be swirled without climbing out. A round-bottom flask is for heating under a condenser, because the heat meets a curved wall and the joint at the neck connects to the rest of the glassware. Borosilicate is the glass that survives the temperature change. These forms are listed under ISO laboratory glassware.
