Overview
Test Tube is a cylindrical glass vessel used for holding, mixing, or heating small quantities of solid or liquid substances. Manufactured via borosilicate glass melting and annealing processes to ensure high thermal shock resistance and chemical inertness.
Application
- Laboratory analysis equipment: Centrifuges, spectrophotometers.
- Chemical processing plants: Reagent storage, titration stations.
- Pharmaceutical manufacturing: Quality control sampling, reaction vessels.
Precautions
- Operate within -20°C to 450°C temperature range; avoid rapid thermal gradients.
- Maximum internal pressure must not exceed 1 atm unless reinforced.
- Clean with non-abrasive solvents; inspect for micro-cracks before reuse.
