The BD FACS™ Lyse Wash Assistant (LWA), with its patented cell wash technology, automates sample preparation for flow cytometry applications. It lyses, mixes, washes, and fixes samples with minimal labor. Automating incubation and washing, the LWA batch processes up to 40 patient samples per run to reduce hands-on time and operatorinduced variability in laboratory data. Samples can be transferred to a BD FACSCanto or BD FACSCalibur flow cytometer for analysis using the LWA carousel.
