What Is a Test Tube Used For in Scientific Research?

Test tubes serve as fundamental tools across laboratories, enabling chemical reactions, biological sample storage, and precise measurements. Over 89% of laboratory workflows require test tubes for temporary substance containment, with 72% of pharmaceutical companies using them for drug compatibility tests. Their cylindrical shape allows minimal surface exposure while facilitating easy observation under microscopes or spectrophotometers.

Material Innovation and Durability

Modern test tubes utilize borosilicate glass 3.3, demonstrating 40% higher thermal shock resistance than standard soda-lime glass. Plastic variants made from polypropylene withstand 134°C autoclaving cycles 500+ times without deformation. A 2023 study showed:

• Glass test tubes: 0% chemical absorption rate
• Plastic tubes: 98.6% recyclability index
• Hybrid coatings: 3x scratch resistance improvement
