Thermo Scientific CW3 Cell Washer

Tuesday, 09 May, 2017 | Supplied by: Thermo Fisher Scientific


Fully automated, the Thermo Scientific CW3 Cell Washer has been engineered to combine the benefits of efficient performance with user-friendly design and safe operation. Users can select one of the preset programs that have been designed to run in automatic mode, accelerate blood cell washing cycles and achieve time savings, while allowing for ease of use and sample safety.

The cell washer has been designed to achieve optimal corpuscle dryness by allowing users to preset the desired decanting speed. At the same time, corpuscle washing is improved via the optional overflow method. It enables precise, thorough, reproducible and rapid blood cell washing of up to 24 tubes in a 3 min run.

For washing, tubes swing at a fixed positive angle to sediment cells rapidly at the bottom of the tube, whereas when decanting, the rotor holds tubes at a slightly negative angle and the saline is decanted centrifugally. The result is optimised pelleting performance. Furthermore, the flexibility to use 12- or 24-place rotors and standardised, repeatable procedures enables the instrument to adapt to the processes and protocols already in place within the lab.

Built with sample safety in mind, the compact cell washer features an automatic alert mechanism that informs users about low or disrupted saline levels and when a run is complete. A view port on top of the unit facilitates quick calibration, while the saline distributor is mounted directly on top of the rotor to reduce the risk of cross-contamination.

The washer is also equipped with tube racks bearing red and blue number labelling for easy sample balancing. When closed-monitoring of the washing process is required, the system can be operated manually to allow for cells that need to be washed step by step. As a low-maintenance instrument, the cell washer includes easy-to-change pump tubing and an easy-to-remove catch basin, rotor and rotating bowl.
