The BioTek Elx405 Select CW is a robust microplate washer built by one of the industry’s leaders in microplate technology.  The ELX405 Select CW from Bio-Tek is the world’s first deep well microplate washer that aspirates and dispenses into 96- and 384-well plates less than 50 mm in height. ANSI/SBS standard microplates are also accommodated, resulting in a total solution for all of a laboratory’s solid bottom microplate washing needs.  The system is capable of cell washing and ideally suited for plate preparation for assays such as ELISA. The new ELx405 Select CW  from BioTek is a robot compatible, full plate washer incorporating Bio-Tek’s patented Dual-Action manifold with independent filling and evacuation control for precise overfill washing and overflow protection.  The Elx405 microplate washer comes equipped with an built-in system check which is used during initial power up to diagnose the health of the instrument. This microplate washer’s carrier has two directions, left to right and front to back. Contact us today to learn more about our Biotek ELx405 Select CW Plate Washing System.
