Description
Test tubes in borosilicate glass 3.3 with round bottom are designed for everyday laboratory sample handling and heating work. Each tube measures 10 × 75 mm with a wall thickness of 0,9/1,0 mm and is produced on automated machines to deliver uniform length and wall dimensions across the batch. Borosilicate 3.3 glass provides the thermal resistance needed when tubes are exposed to open flame, heating blocks or hot water baths, while the clear walls allow straightforward visual inspection of contents. These tubes from manufacturer ISOLAB Laborgeräte are supplied in packs of 100 pieces, supporting efficient stocking in teaching labs, research groups and routine analytical workflows. The round-bottom geometry seats securely in standard racks and heating accessories. Within the same product family, neutral glass options are also available; this borosilicate version is the preferred choice whenever elevated temperatures are expected. Consistent dimensions help maintain reproducible handling from tube to tube during serial tests, incubations or simple storage of liquid samples.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about tube à essai - verre borosilicate - 10x75 mm
What is this article?
tube à essai - verre borosilicate - 10x75 mm is the article on this page. Luminix Health distributes ISOLAB for laboratory use. It sits in Ballons à fond rond, inside Béchers & fioles, 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.
