Globe Scientific 12x75mm Test Tube | Amber Polypropylene, 5mL, Case of 2000

Safeguarding light-sensitive samples is a critical challenge in clinical and analytical workflows. The Globe Scientific 110441AM Amber Test Tube is specifically engineered to protect vulnerable compounds—such as bilirubin, vitamins, or light-sensitive diagnostics—from damaging UV degradation. Measuring a standard 12x75mm with a 5mL capacity, these tubes integrate flawlessly into automated analyzers, centrifuges, and standard rack systems without requiring specialized adapters.

Manufactured from robust, premium polypropylene (PP), these tubes offer significantly higher impact resistance and chemical stability compared to standard polystyrene tubes, ensuring they will not shatter if dropped. The amber tint is molded directly into the plastic, providing permanent light protection that cannot scratch off like applied coatings. Supplied in an economical case of 2,000 (divided into 2 convenient bags of 1,000), these tubes are the preferred choice for high-volume labs requiring dependable light protection.

Features and Benefits

• Amber UV Protection: The deep amber tint effectively blocks damaging ultraviolet light, preserving the integrity of light-sensitive analytes and reagents.

• Shatterproof Polypropylene: PP construction delivers superior durability and impact resistance, eliminating the safety hazards associated with glass or brittle polystyrene tubes breaking in centrifuges.

• Standard 12x75mm Profile: The universally accepted 5mL dimensions ensure perfect compatibility with existing laboratory centrifuges, vortex mixers, and automated clinical analyzers.

• Chemical Resistance: Polypropylene is highly resistant to a broad spectrum of standard laboratory chemicals, solvents, and biological buffers.

• High-Volume Packaging: Packaged as 2,000 tubes per case (2 inner bags of 1,000) to support the demanding workflows of high-throughput testing facilities.

Frequently Asked Questions

Can I centrifuge these polypropylene tubes?
Yes, polypropylene (PP) is highly durable and excellent for centrifugation. It possesses higher chemical resistance and impact strength than clear polystyrene (PS) tubes, though it is slightly more translucent rather than glass-clear.

Do these tubes include caps?
No, the 110441AM SKU includes the tubes only. Compatible 12mm flanged plug caps or grip caps can be purchased separately.

Will the amber color scratch off?
No, the amber coloration is physically mixed into the polypropylene resin before molding. It is not an external coating, so it cannot be scratched off or degraded by solvents.
