Thermo Scientific Centrifuge Swing Bucket for TX-400 5000 rpm Set of 4 Buckets

Thermo Scientific TX-400 Round Rotor Buckets (75003655) – Set of 4 x 400 mL

The Thermo Scientific TX-400 Round Rotor Buckets (75003655) are high-performance, general-purpose centrifuge buckets sold as a factory-matched set of four. Engineered to drop seamlessly onto the TX-400 swinging bucket rotor cross (75003181), each bucket provides a generous 400 mL capacity for a total processing volume of 1.6 liters per run. These buckets are certified to reach operational speeds up to 5,000 RPM and are standard across major Thermo Scientific benchtop centrifuge series to support cell culture harvesting, clinical batching, and general blood separation workflows.

Technical Performance & Design

• High-Capacity Round Geometry: Designed with an open, 400 mL individual bucket volume that effortlessly handles large-format bottles or accommodates modular adapters for multi-tube processing arrays.
• Aerosol-Tight Containment Support: Engineered with a specialized upper rim profile designed to accept ClickSeal biocontainment lids (75003656), providing rapid, one-handed click closures that seal in biological hazards and volatile vapors.
• Engineered Metallurgy: Machined from ultra-pure, high-tensile alloy compounds designed to handle rapid deceleration and maximum physical stress loads up to 4,696 x g without metal fatigue.
• Symmetrical Weight Calibration: Distributed strictly as a matched lot of 4 buckets, ensuring that baseline structural weight metrics are perfectly uniform across opposite positions to avoid centrifuge axis wobble and auto-shutoffs.
