50 mL Self-Standing Transport Tubes

Molded from high-clarity polypropylene (PP), these tubes are paired with leak-resistant high-density polyethylene (HDPE) screw caps to prevent fluid migration during aggressive vortexing or cross-facility courier transit. Available in sterile, non-sterile, and highly specialized metal-free iterations, this product family covers applications spanning cellular biology, trace metal analysis, and general clinical specimen archiving.

Key Functional Benefits:

• Ergonomic Self-Standing Skirt: Allows technicians to easily execute single-handed pipetting and fluid additions by eliminating the constant reliance on a dedicated test tube rack
• Leak-Resistant HDPE Closures: Precision-threaded caps provide a robust, liquid-tight seal that safeguards precious specimens during high-speed mixing, rocking, or pneumatic tube transport
• Trace Metal-Free Variation: The specialized 6255MF configuration is meticulously processed to minimize trace element background levels, preventing analytical interference during ICP-MS assays
• Certified Molecular Cleanliness: All sterile packaging options are strictly verified to be RNase-, DNase-, and Pyrogen-free, protecting sensitive nucleic acid targets from enzymatic degradation

IMPORTANT! Autoclaving Structural Guidelines: While the premium polypropylene tube bodies can safely undergo standard steam sterilization cycles (121°C), the high-density polyethylene (HDPE) screw caps cannot tolerate the same structural thermal limits. Always entirely remove or completely unthread the caps prior to entering the autoclave chamber to avoid irreversible plastic warping or failure.
