Readers / Automated Systems

Abraxis offers a variety of equipment for measuring optical signal produced by ELISA, RBA, and other assay types, from the fully-automated CAAS to basic readers.

Cyanotoxin Automated Assay System (CAAS)
PN 475200, CAAS, Microplate format, 96 well, without computer and printer, installation included
PN 000111, CAAS Training, On-site

CAAS is an automated, “hands off”, microtiter plate format analyzer for quantitative determination of anatoxin-a, BMAA, cylindrospermopsin, microcystins and saxitoxins. The analyzer is computer controlled and capable of automating all the steps of both ELISA and RBA assays including fluid handling, plate mixing, incubation/timing, optical reading, calculations and reports.

Assay automation with CAAS is easy, reliable, and consistent; moreover, multiple analyte assays can be run simultaneously (multiplexing). Testimonials
