Test Tube PP Plastic - 16mm dia. x100mm

Stoppers sold separately.

These polypropylene (PP) plastic test tubes (16mm diameter x 100mm) are popular in labs because they're shatterproof, chemically resistant and autoclavable. Unlike glass, they don't break when dropped, which greatly reduces the risk of injury or losing your sample.

Key Benefits of Polypropylene

Polypropylene balances physical and chemical properties in a way that makes it a standard choice for many lab jobs:

• Durability and safety: PP is impact-resistant and flexible, so it can be bent or dropped without shattering, which makes it safer in schools and fieldwork.
• Centrifuge strength: It withstands mechanical stress and high centrifugal forces (often up to 12,000 to 15,000 x g) without deforming or cracking.
• Temperature range: Typically -80°C to +121°C, so PP tubes can go in the deep freezer or the autoclave.
• Chemical inertness: It resists many organic solvents, and most acids, bases and alcohols. Its water-repellent surface also reduces protein and nucleic acid binding, which matters in biological assays.

Common Applications

• Sample storage: Long-term storage of biological samples, as the tubes cope with freezing.
• Microbiology and cell culture: PP can be sterilised for contamination-free culture work.
• PCR: Its thermal stability suits the fast temperature changes of polymerase chain reaction (PCR).
• High-throughput labs: Light, standard-sized tubes suit automated equipment and robotic handling.
