This four filter bichromatic calculating strip reader features a touch screen interface, on-board graphics printer, and a non-volatile memory to store over 50 user-defined tests. The standard model includes 4 filters, making it possible to load up to 3 strips at a time, and six-filter options are available. The onboard data reduction calculation includes regression to plot curve fitting and cut off absorbance calculation. This is made simple with step my step user prompting and the new larger screen display and graphical capabilities. It has a large- non-volatile memory to store over 100 user tests which can be transferred using parallel and serial outputs or printed via the optional onboard printer. The Strip Reader includes a carrier for break-apart strips up to 12 wells long. Optional carriers are available to accommodate non break-apart (rigid) 8-well or 12-well strips.
