Engineered to fit directly into the round buckets of the TX-400 swinging bucket rotor assembly, these adapters permit the safe, high-speed centrifugation of standard 50 mL conical tubes. This lot of four ensures uniform weight distribution and exact balancing across all four positions of a standard general-purpose benchtop centrifuge line.\u003c\/p\u003e\n\u003ch3\u003eTechnical Performance \u0026amp; Design\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eTX-400 Rotor Optimization: Engineered to lock precisely within Thermo Scientific **TX-400 swinging bucket rotor cross-platforms**, eliminating rotational rattling and tube misalignment under maximum RCF.\u003c\/li\u003e\n\u003cli\u003eHigh-Capacity Conical Support: Each adapter is bored to support **50 mL conical tubes** (such as Falcon™ or Nunc™ lines) with a strict individual cell capacity, yielding a total rotor capacity of **16 x 50 mL conical tubes** per run.\u003c\/li\u003e\n\u003cli\u003ePrecision Cavity Geometry: Formed with an internal profile measuring **29.5 x 116 mm** to match the strict taper of 50 mL conical bottom walls, providing complete baseline support to prevent tube stress fractures at high velocities.\u003c\/li\u003e\n\u003cli\u003eAdvanced Polymer Construction: Fabricated from high-density, chemical-resistant resin designed to withstand aggressive sanitizers, solvents, and continuous mechanical compression stress without micro-cracking.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eProduct Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eCatalog \/ Part Number: 75003683 (75-003-683)\u003c\/li\u003e\n\u003cli\u003eRotor Compatibility: Thermo Scientific TX-400 Swinging Bucket Rotor\u003c\/li\u003e\n\u003cli\u003eCentrifuge Compatibility: Thermo Scientific Sorvall ST16 \/ ST16R, Megafuge 16 \/ 16R, SL16 \/ 16R, and General Purpose Pro Series\u003c\/li\u003e\n\u003cli\u003eTube Format: 50 mL Conical Tubes\u003c\/li\u003e\n\u003cli\u003eCavity Dimensions (Ø x L): 29.5 x 116 mm\u003c\/li\u003e\n\u003cli\u003eLot Quantity: Complete factory pack of 4 adapters\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eKey Benefits \u0026amp; Applications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eCell Culture \u0026amp; Pellet Harvesting: Essential for heavy **mammalian or bacterial cell culture clarification** steps where cells must be uniformly pelleted into the tip of 50 mL conical vials.\u003c\/li\u003e\n\u003cli\u003eSymmetrical Weight Balancing: Supplying a matching **lot of 4 adapters** guarantees consistent tare weight benchmarks across opposite rotor positions, mitigating sample imbalance shutoffs.\u003c\/li\u003e\n\u003cli\u003eAutoclaved Cross-Sanitization: The high-performance resin allows for repetitive **steam autoclaving cycles (121°C)** to meet strict bio-safety guidelines in sensitive tissue culture workflows.\u003c\/li\u003e\n\u003cli\u003eErgonomic Sample Loading: Smooth finger lips allow for swift removal from the bucket interior, making batch hand-offs from biological hoods to the centrifuge chamber rapid and seamless.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003cp\u003e\u003csmall\u003eThermo Scientific™ and Sorvall™ are registered trademarks of Thermo Fisher Scientific Inc.
