Glass Test Tubes

Laboratory-grade clear glass test tubes, made from Borosilicate 3 glass. These glass test tubes have high thermal and chemical resistance, making them ideal for a wide range of laboratory experiments and testing.

Standard rimmed tubes can crack if a stopper is wedged too deeply into the flare. The rimless shape is also easier to sterilise and clean, and more suitable for sample archiving, centrifuge rotors, and compact racking.

The benefits of rimless glass test tubes

• Uniform Heat Transfer: Consistent results when used with burners or water bath heating
• Suitable for Automated Use: Rimless openings make these test tubes suitable for robotic grippers and capping machines
• Easier Cleaning: Rimless design ensures zero residue after sterilisation
• Borosilicate Glass: Made from durable, chemical-resistant and thermal-resistant glass
