Description
Test tubes in neutral glass with round bottom, measuring 12 x 75 mm and with a wall thickness of 0,8/0,9 mm, serve as compact vessels for routine laboratory sample handling, reagent reactions and short-term storage. Produced on automated machines for uniform length and wall thickness, they ensure consistent dimensions across every piece in the pack. Neutral glass is one of two glass types available in this series; these tubes are suited to general chemical and biological work where elevated heating demands are not the primary requirement. The round-bottom design aids mixing and seating in standard small-tube racks. Each pack contains 100 non-sterile pieces and comes from manufacturer ISOLAB Laborgeräte. The compact 12 mm diameter and 75 mm length make them practical for teaching laboratories, quality-control benches and research workflows that need reliable, uniformly manufactured glassware for sample preparation and qualitative analysis without unnecessary bulk.
This article is part of Round-bottom flasks, in Beakers & flasks. See also Flat-bottom flasks.

Questions about tube à essai - verre neutre - 12x75 mm
What is this article?
tube à essai - verre neutre - 12x75 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.
