Description
Test Tubes Round Bottom, Rimless are designed for routine heating, mixing, and reaction work where smooth handling, reliable thermal performance, and easy cleaning are essential. The round bottom profile promotes efficient swirling and uniform heat distribution during gentle heating, while the rimless finish provides a clean, straight tube mouth that is well suited to use with test tube racks, closures, and automated washing processes. These tubes are widely used in teaching laboratories, sample preparation, qualitative analysis, and general bench procedures.
Manufactured from high quality laboratory glass, these test tubes provide dependable chemical resistance to common reagents and solutions, supporting routine use with acids, alkalis, salts, and many solvents depending on concentration and temperature. Smooth internal surfaces minimise residue retention and support efficient cleaning between uses, while consistent wall thickness improves durability during daily handling. The rimless design also reduces edge chipping points compared with rolled rim styles, which can be beneficial in high use environments where tubes are frequently loaded, unloaded, and washed.
Standards and compliance context: Where supplied in borosilicate glass, tube performance is commonly referenced to borosilicate laboratory glass standards such as ISO 3585 and ASTM E438 Type I, supporting expectations for chemical durability and thermal behaviour. Always confirm the glass type and any supplied compliance documentation if your laboratory requires formal verification.
Supplied by LabChoice Australia, these round bottom rimless test tubes are used across Australian schools, universities, research facilities, medical laboratories, and industrial QC environments where reliable, easy to clean tubes support consistent daily laboratory workflows.
