Quick-Seal Tube 342414: a Precision Component for Demanding Medical Environments
The Beckman Coulter 342414 tube is a high-performance centrifuge consumable used in medical and biological procedures. Made from polyallomere, a material prized for its chemical and mechanical resistance properties, this tube is optimised for rotation speeds of up to 70,000 rpm depending on the rotor used, while withstanding a maximum centrifugal force of 504,000 g. It is primarily used in preparative ultracentrifugation protocols, where precision and safety are paramount.
Thanks to its Quick-Seal technology, the 342414 tube can be hermetically sealed by heat, eliminating the need for additional caps or seals. This feature significantly reduces the risk of cross-contamination or leaks during centrifugation cycles, making it a reliable choice for sensitive applications such as the separation of nucleic acids, lipoproteins or protein complexes.
The tube has a usable volume of 39 mL, compatible with Type 70 Ti and Type 50.2 Ti fixed rotors, both commonly used in biomedical research platforms and hospital laboratories. Its standard dimensions (25 x 89 mm) allow for optimal loading without the need for complex adapters, while ensuring homogeneous sample distribution under high acceleration.
When used with the right accessories, such as spacers, this tube fits easily into high-throughput centrifugation routines, which are often essential in virological studies, plasmid purification or density gradient analysis. It meets strict standards for reliability, biological safety and chemical compatibility, making it an essential component in the analysis chain for high-stakes biomolecules.
