Product Overview
The Polylab Test Tube with Screw Cap is engineered for modern laboratory workflows where secure sample containment, chemical resistance, and workflow compatibility are non-negotiable. Available in polypropylene or polystyrene, these tubes offer unmatched reliability across clinical, research, industrial, and academic lab environments.
Superior Material, Smarter Design
Crafted using chemically inert polymers, these tubes withstand aggressive reagents and physical stress without cracking or degrading. Polypropylene variants are heat-stable and autoclavable, ideal for sterilization and reuse. Polystyrene versions offer crystal-clear visibility—perfect for sample inspection or colorimetric analysis.
The screw-cap mechanism is a standout feature, offering superior sealing over snap or push-fit alternatives. This leak-proof design is vital during centrifugation, transport, or temperature fluctuations, ensuring your sample stays safe and uncontaminated. Researchers in microbiology, biochemistry, or diagnostic labs rely on this security to maintain sample integrity during sensitive experiments.
Ready for Real Lab Conditions
These tubes integrate seamlessly with standard centrifuge rotors, tube stands, and storage boxes, helping streamline operations across departments. Whether you’re spinning samples, storing reagents, or collecting specimens, these tubes fit perfectly within your existing setup—no custom holders or adapters required.
The interior surface is ultra-smooth to prevent residual adhesion, ensuring accurate sample recovery and easier cleaning. This also helps minimize cross-contamination, especially during serial dilutions or sample transfers.
Color-Coded Efficiency
To support high-throughput labs and sample-heavy workflows, Polylab offers color-coded caps that simplify sample tracking. Ribbed caps provide better grip—especially useful when wearing gloves—reducing time and improving safety in fast-paced environments like hospitals or teaching labs.
Certified Safe & Sterile
Every tube undergoes strict quality control, ensuring it’s free from DNase, RNase, and pyrogens, making them ideal for molecular biology or clinical applications. Built under GMP-compliant protocols, these tubes meet international labware standards for both research and diagnostic purposes.
