MEDILAB Test Tubes are high-quality cylindrical vessels designed for holding, mixing, heating, and observing small quantities of liquid or solid samples during laboratory procedures. Made from Borosilicate Glass 3.3, they offer excellent clarity, chemical resistance, and thermal stability—making them essential tools across scientific, academic, and industrial laboratories. Their consistent performance ensures accurate results in routine analysis, qualitative tests, research experiments, and controlled reactions.

Key Features

• High-clarity borosilicate construction for accurate visual observation of samples.
• Outstanding thermal shock resistance, ideal for heating, boiling, and autoclaving.
• Chemical-resistant glass suitable for acids, alkalis, organic solvents, and reagents.
• Uniform wall thickness for durability, consistent heating, and lab safety.
• Rounded bottom design ensures easy mixing and residue-free cleaning.
• Smooth rim finish for safe handling and compatibility with rubber stoppers.
• Available in multiple sizes to suit diverse analytical and research needs.
• Reusable & long-lasting, providing excellent cost efficiency for laboratories.

Handling & Precautions

• Do not subject cold tubes directly to high heat; allow gradual temperature change.
• Avoid sudden quenching after heating to prevent glass stress.
• Clean with mild detergents and dedicated test tube brushes for best results.
• Autoclave safely at recommended temperatures (121°C, 15 psi).
• Do not use with highly abrasive materials to avoid scratching the inner surface.
• Store in racks or protective containers to minimise breakage.
• Ensure proper drying before heating to prevent cracking.
