Sigma Centrifuge Rotor Bucket Adapter 50 ml Lot of 2 Inserts

Description

The Sigma 18052 is a precision-engineered rotor bucket adapter designed to facilitate the secure and balanced centrifugation of 50 ml conical tubes. These inserts are manufactured from high-density, chemically resistant polyoxymethylene (POM) or similar high-grade polymers, ensuring durability under high relative centrifugal forces (RCF). By providing a snug, contoured fit for standard 50 ml tubes, these adapters minimize tube vibration and prevent structural failure during high-speed sedimentation runs.

Technical Performance and Design

• Optimized Geometry: Specifically contoured to support the conical base of standard 50 ml centrifuge tubes (such as Falcon™ or Corning™ brands), ensuring even distribution of g-force across the tube wall.

• Vibration Reduction: Engineered to provide a precision fit within the rotor bucket, reducing mechanical “play” and ensuring a smooth, quiet run even at maximum rated speeds.

• Chemical Resilience: Constructed from materials resistant to common laboratory solvents, detergents, and biological buffers, allowing for easy decontamination and long-term use in rigorous lab environments.

• Balanced Performance: This lot of two adapters is matched to maintain rotor symmetry, which is critical for preventing spindle wear and ensuring the longevity of the centrifuge motor.

Product Specifications

Key Benefits

• Enhanced Sample Safety: Prevents tube “bottoming out” or crushing by providing bottom-up support during the deceleration and acceleration phases.

• Easy Insertion/Removal: Features a flanged top or easy-grip rim (depending on specific revision) to allow for rapid sample loading and unloading during high-throughput workflows.

• Autoclavable: Most Sigma polymer adapters are designed to withstand standard autoclaving cycles (121°C) for sterile research applications.
