These disposable, clear polypropylene tubes are best suited for procedures requiring high optical clarity, and thermal and chemical stability. Provide reliable containment of laboratory fluid samples.

• Dual position snap-cap prevents sample loss with ease of handling, heavier gauge walls, and unique construction provide a secure, positive seal
• Medical-style packaging materials
• 17×100 mm tubes have blue printed graduations and white writing patch
• Tube dimensions and volumes are approximate
• Widely used and referenced in laboratory protocols
• Sterile, nonpyrogenicity tested to less than 0.1 EU/ml (Cat. No. 352002 nonsterile)

3000 RCF rating (RCF claims refer to relative centrifugal force measured in g-force for materials with a specific gravity of 1.0 used in an appropriate rotor with correct cushion and safety precautions. Tubes used with organic solvents at temperatures below 0 °C may have lower RCF ratings).
