Designed with a 0.5 mL (500 µL) working volume capacity, these tubes are injection-molded from high-purity, ultra-clear polypropylene (PP). The structural layout is distinguished by a skirted conical base that provides standalone stability on benchtops, paired with vertical external knurling (ribs) that lock directly into specialized laboratory workstation racks for efficient, one-handed cap manipulation. Rated to withstand extreme centrifugal forces up to 20,000 x g, these tubes utilize a secure screw cap closure embedded with an Ethylene Propylene Diene Rubber (EPDM) O-ring, delivering a certified vapor-tight and leakproof seal that eliminates the risk of sample evaporation or cross-contamination during intensive fluidic loops.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Performance and Design\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003cp style=\"margin: 0;\"\u003e\u003cb\u003e20,000 x g Heavy Centrifugation Rating:\u003c\/b\u003e Structurally validated to withstand high-velocity g-forces in standard microcentrifuges.
