Test Tube PP Plastic - 16mm dia. x100mm

Stoppers sold separately.

Polypropylene (PP) test tubes are widely used in laboratories because they are shatterproof, chemically resistant, and autoclavable. Unlike glass, they do not break upon impact, which significantly reduces the risk of injury or sample loss from accidental drops. 

Key Benefits of Polypropylene

• Polypropylene offers a unique balance of physical and chemical properties that make it a standard choice for many lab applications:
• Durability and Safety: PP is highly impact-resistant and flexible, meaning it can be bent or dropped without shattering. This makes it safer for use in educational settings and fieldwork.
• High Centrifugation Strength: Because it can withstand mechanical stress and high centrifugal forces (often up to 12,000–15,000 x g) without deforming or cracking, PP is the preferred material for centrifuge tubes.
• Thermal Stability: It can withstand a wide temperature range, typically from -80°C to +121°C. This allows PP tubes to be used for both deep-freeze storage and sterilization in an autoclave.
• Chemical Inertness: It resists many organic solvents, as well as most acids, bases, and alcohols. Its hydrophobic surface also helps reduce protein and nucleic acid binding, which is critical for biological assays.

Common Applications

• Sample Storage: Frequently used for long-term storage of biological samples due to its leak-proof screw cap options and ability to endure freezing.
• Microbiology and Cell Culture: PP is ideal for growing cultures because it can be sterilized to ensure a contamination-free environment.
• PCR Assays: Its thermal stability makes it suitable for the rapid temperature changes required in Polymerase Chain Reaction (PCR).
• High-Throughput Labs: Its lightweight nature and standardized dimensions make it compatible with automated laboratory equipment and robotic handling.
