Round-Bottom Polystyrene Test Tubes

• Widely used and referenced in laboratory protocols
• Dual position snap-cap prevents sample loss with ease of handling; provides a secure, positive seal (except for items 352008, 352017, and 352052 which do not have caps) 
• Sterile, nonpyrogenicity tested to less than 0.1 EU/mL (Cat. No. 352008 nonsterile)

The foundation for consistent research results

• Provide reliable containment of laboratory fluid samples
• Polystyrene tubes are best suited for procedures requiring high optical clarity
• Heavier gauge walls; unique construction 
• Medical-style packaging materials
• 1,400 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.)
• Tube dimensions and volumes are approximate
