Description
Sample tubes, PS, 13 x 75 mm, round bottom are laboratory consumables intended for sample collection, short-term holding and processing in analytical, clinical and research settings. Manufactured from polystyrene (PS), they provide optical clarity for visual checks and a nominal volume of 0,0051 l. With a diameter of 13 mm, height of 75 mm and round-bottom form, the tubes locate securely in standard racks, blocks and many autosampler systems. Packs of 1000 pieces support high-throughput laboratory routines while ensuring dimensional uniformity. These sample tubes from manufacturer Ratiolab are appropriate for aqueous samples and everyday procedures where polystyrene chemical compatibility is suitable. They integrate into reagent-tube, sample-tube and autosampler workflows typical of quality-control, diagnostic and general laboratory environments. The round-bottom geometry assists mixing and recovery of modest volumes, while the lightweight design eases handling and transport under normal laboratory temperature conditions. They offer a clear, practical solution for routine sample management without superfluous features.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about Test Tubes, PS, 13 x 75 mm, round bottom
What is this article?
Test Tubes, PS, 13 x 75 mm, round bottom is the article on this page. Luminix Health distributes Ratiolab for laboratory use. It sits in Round-bottom flasks, inside Beakers & flasks, in Matériel de laboratoire.
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.
