Beckman Coulter Quick-Seal® 342412 Tube – Precision and Safety in Medical Environments
The Beckman Coulter model 342412 is a Quick-Seal® polyallomer tube designed to meet the most rigorous requirements of medical and biomolecular research laboratories. This single-use tube has a size of 13 × 51 mm and a usable capacity of 5.1 mL, making it the preferred choice for applications requiring low-volume sample processing while ensuring consistent performance at very high speeds.
This tube is specifically manufactured to withstand centrifugation speeds of up to 90,000 rpm, generating a centrifugal force of 645,000 g. These mechanical characteristics make it particularly suitable for analysis protocols, particularly in virology, cell biology, or during detailed clinical analyses requiring high separation rates and rigorous reproducibility. Its k factor of 10 attests to its ability to perform effective separations in a short time, thus optimising laboratory processing cycles.
The Quick-Seal® design provides thermal sealing, preventing the risk of leakage or cross-contamination, which is essential in environments subject to biosafety standards. The 342412 tube is used with specific spacers and can also be combined with floating spacers for applications requiring optimised adjustment of the volume or centre of gravity of the tube.
Fully compatible with ultracentrifuges that accept high-speed rotors designed for 13 × 51 mm tubes, this model is part of a range of reliable consumables that have been proven in hospital and academic protocols. Its polyallomer material combines transparency and strength, facilitating observation of gradients while maintaining sample integrity under extreme stresses.
