Description
Test Tubes, Round Bottom with Rim are designed for routine laboratory heating, mixing, and sample handling where durability, safe gripping, and consistent thermal performance are essential. The round bottom profile supports efficient swirling and more uniform heat distribution during gentle heating, making these tubes well suited to qualitative analysis, small scale reactions, and general teaching and research procedures. The rolled rim provides a stronger edge for handling with test tube holders or tongs and helps reduce chipping at the mouth during frequent use.
Manufactured from high quality laboratory glass, these test tubes offer dependable chemical resistance to common laboratory reagents and solutions, supporting routine work 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 robustness during daily handling and washing. The rim also supports use with stoppers or caps where required, providing a practical sealing surface for short term storage or controlled procedures.
Standards and compliance context: Where supplied in borosilicate glass, performance is commonly referenced to recognised borosilicate laboratory glass standards such as ISO 3585 and ASTM E438 Type I, supporting expectations for chemical durability and thermal behaviour. If your application requires formal verification, confirm the glass type and any available compliance documentation.
Supplied by LabChoice Australia, these round bottom test tubes with rim are widely used across Australian schools, universities, research institutes, medical laboratories, and industrial QC environments for reliable everyday laboratory work.
