Glass test tubes

Glass test tubes are a staple of every working laboratory, and SmartLabs stocks a full range to suit schools, universities, research facilities and medical labs across South Africa. The collection covers borosilicate glass test tubes, soda-lime glass test tubes, and plastic-capped options, in popular sizes from 10 x 75 mm up to 25 x 150 mm, with both rimmed and rimless styles available.

Borosilicate glass is the material of choice for most laboratory applications. It resists thermal shock, tolerates direct flame and autoclave sterilisation, and holds up against a wide range of chemicals, making it the right call for heating reactions, culturing microorganisms, or any work where contamination and breakage carry a real cost. Soda-lime glass test tubes cover lighter-duty general use and are a cost-effective option for high-volume school lab sessions.

The rimmed style gives you a secure grip point for clamps and makes it straightforward to fit stoppers, cotton plugs or caps. Rimless tubes have fire-polished openings that are easier to stack and clean, and pair well with standard test tube plugs. Capped options keep samples sealed for storage or transport.
