The glass test tubes from AllChimie are the reference cylindrical vessels for small reaction volumes, qualitative tests and incubations. Manufactured from borosilicate glass 3.3, they withstand temperature variations, direct flame heating and sterilisation operations.
Available with or without rimmed neck (rolled edge), in standard diameters (Ø 10, 12, 13, 16, 18, 20, 25 mm) and various lengths (75 to 200 mm), these tubes fit all standard racks, bench centrifuges and heating baths. Some references are offered with screw caps for tight conservation.
Used daily in biology, microbiology, analytical chemistry, quality control and education, they are the base consumable for micro-scale protocols. Some sterilised or standard-compliant versions are available for sensitive applications.
At a workstation, test tubes are held vertically in a rack calibrated to the right diameter, sampled with a graduated pipette or Pasteur pipette, and sealed with rubber stoppers or silicone stoppers depending on sterilisation needs. For manual stirring, the glass stirrer efficiently complements the equipment.
