Test Tube

Test Tubes are narrow laboratory glassware tubes used for holding, mixing, heating and observing small liquid or sample volumes. Available in options such as graduated and stoppered BORO 3.3 glass designs, they support sample handling, reactions and routine testing. Australian laboratories, schools and universities use test tubes for reliable practical experiments, sample preparation and science education workflows.

Test Tubes with Graduation and Stopper, BORO 3.3 Glass are designed for holding, mixing, observing and temporarily storing compatible liquid or solid samples during routine laboratory work. The transparent glass body allows users to view sample colour, clarity, separation, sediment formation and reaction changes without opening the tube.

The graduation marks provide a convenient visual guide when adding or comparing sample quantities. These markings should be treated as approximate unless the manufacturer supplies confirmed tolerance, calibration or volumetric accuracy information. For analytical measurements requiring defined accuracy, laboratories should use calibrated volumetric glassware rather than relying on graduated test tubes.

The supplied stopper helps cover the opening during compatible sample handling and short-term storage. Users should not assume that the stopper provides a gas-tight, pressure-tight or leakproof seal unless this is confirmed in the product documentation. Stopper and sample compatibility should also be checked before use, particularly when working with solvents, corrosive chemicals or volatile materials.

BORO 3.3 borosilicate glass has low thermal expansion and defined chemical durability properties, making it widely used for laboratory glassware. ISO 3585 specifies the properties of borosilicate glass 3.3, while ASTM E438 covers glass types commonly used in laboratory apparatus. These standards are relevant material references but should only be stated as confirmed product compliance claims when supporting manufacturer documentation is available.

ISO 4142 specifies test tubes suitable for general laboratory use and includes tubes manufactured from borosilicate, neutral and soda-lime glass. It provides a recognised technical reference for laboratory test tube construction and dimensions. The standard does not automatically confirm that a particular product complies with its requirements unless compliance has been verified by the manufacturer.

Before use, each tube should be checked for cracks, chips, damaged graduations or contamination. The stopper should be removed before heating, and a closed tube should never be heated because pressure may build inside. Users should also confirm the tube size, stopper fit, chemical compatibility, temperature limits and laboratory method requirements before use.

For LabChoice Australia customers, Test Tubes with Graduation and Stopper, BORO 3.3 Glass provide a practical option for schools, universities, research laboratories, quality control facilities, industrial laboratories and routine chemistry workflows requiring visible sample handling with approximate graduated reference markings.
