Sigma Centrifuge Rotor Bucket Adapter 15 ml 1 Insert

The Sigma 18016 is a high-performance centrifuge rotor bucket adapter designed to provide a secure and balanced fit for specialized sample vessels within Sigma swing-out rotor systems. Engineered from high-density, chemically resistant polymers, this adapter ensures structural integrity under significant G-forces (RCF). By isolating the sample tube from direct contact with the metal bucket and providing lateral support, the 18016 insert minimizes the risk of tube breakage and ensures consistent sedimentation patterns across all rotor positions.

Technical Performance and Design

• Precision-Molded Geometry: Specifically engineered to fit Sigma 11140 and 11150 series swing-out rotors, ensuring a zero-play interface between the insert and the bucket wall.

• Load Distribution Technology: Designed to evenly distribute centrifugal pressure across the surface area of the sample vessel, preventing "bottom-out" stress and ensuring balanced operation.

• High-Grade Material Construction: Manufactured from polyoxymethylene (POM), providing high mechanical strength, low friction, and excellent dimensional stability over repeated high-speed cycles.

• Easy-Access Rim: Features a flanged upper rim for rapid insertion and removal from the rotor bucket, facilitating efficient high-throughput sample processing.
