Centrifuges, Cell Washers, CW3
CW3 Cell Washer
Precise, automated performance designed to provide thorough, reproducible blood cell washing. Simplify your work and reduce the time required to wash blood cells with the Thermo Scientific CW3 Cell Washer, the clear choice for trouble-free automation of washing steps for antiglobulin testing. Set all steps of the wash cycles just once and operate the unit by simply loading therotor, shutting the cover and pressing the start key.
Subsequent Applications
Antiglobulin tests, ABO compatibility, Rh testing, Cross matching and Antibody screening.
Fits in
- To your space, with its compact footprint
- To your processes and protocols, with flexibility of 12- or 24-place rotors and standardized, repeatable procedures
Stands out
- Fully automated cell washing cycle saves time
- User-friendly operation with keypad control and easy-to-read digital displays
- Automatic alerts indicate if the saline level is low, and when a run is complete
Efficient Performance
- Fast run– finish washing 24 samples in 3 minutes
- Achieve optimal corpuscle dryness by setting desired decanting speed
- Improve corpuscle washing with optional overflow method during centrifugation step
- Optimize pelleting performance
- For washing, tubes swing at a fixed positive angle to sediment cells rapidly at the bottom of the tube
- For decanting, the rotor holds tubes at a slightly negative angle and the saline is decanted centrifugally
User-Friendly Design
- Save time with pre-set programs in automatic mode
- Manual mode available to wash the cells step-by-step, allowing closed monitoring of washing process
- Tube racks with red and blue number labeling for easy sample balancing
- Cleaning convenience with easy-to-remove catch basin, rotor and rotating bowl
Safe Operation
- Automatic alerts for low or disrupted saline level and for a completed run
- View port on top of unit is available for speed calibration
- Reduces risk of cross-contamination with the saline distributor mounted directly on top of the rotor
- Low-maintenance design with easy-to-change pump tubing
