Test tubes are available in various formats suitable for sample preparation, heating, mixing, and analysis of both liquid and solid materials. Manufactured from borosilicate glass 3.3 or other materials resistant to chemical agents, they provide good thermal resistance, high inertness, and dimensional stability compatible with repetitive handling. Their standardized geometry ensures compatibility with racks, centrifuges, and heating systems, while maintaining tolerances suited to analytical requirements. Depending on the model, they may be autoclavable or compliant with ISO or DIN standards, supporting controlled use in research, quality control, and in the chemical, cosmetic, and food industries. A complete range is available to meet routine laboratory needs.
