STAT FAX 4200 Microplate Reader

The Stat Fax 4200 Microplate Reader is a compact, microprocessor-controlled, multi-purpose
photometer system designed to read and calculate the results of assays, which are read in 96
well microtiter plates or strip trays. The microplate reader may be used for in-vitro diagnostics. It is a user-programmable open system with selectable plate formatting, alphanumeric test naming, automatic interpretation options, duplicate well options, curve plotting and editing, flags and error messages from which the user can create a menu of pre-programmed assays for instant recall. This instrument is intended to be used as a stand-alone instrument without a PC but it has a connection in the event a user wishes to download results.

Stat Fax 4200 reads monochromatically (optional) or bichromatically (optional) and has two

  • Four-filter model (405, 450, 492, and 630 nm)
  • Six-filter VIS model (405, 450, 492, 545, 600, and 630 nm)


Substitute filters in the range of 405 nm – 750 nm are available on special order

Stat Fax 4200 accepts all standard microplates. Trays containing microstrips may also be read
whether they are 12 wells in length, 8 wells or even partial strips.

The software allows the operator to create, edit and store assays. Standard
curves are also stored in this memory. Test protocols remain stored until either changed or
deleted by the user.

TheStat Fax 4200’s optical system provides an economical and low maintenance design which reads 8 wells simultaneously. A 96 well plate can be read and printed in the absorbance mode in approximately ten seconds. Light from a lamp installed in a sealed light-tight compartment is filtered using a rotating filter wheel. The filtered light is then divided into 8 channels using a fiber optic bundle. The plate carrier precisely positions each row of 8 wells into the optical path for reading. Light passing through the 8 wells is directed to 8 photo-detectors. The filter wheel moves to a second position to read the 8 wells at a second wavelength. Using bichromatic differential absorbance values corrects for optical imperfections in the plastic wells and removes the effects of meniscus and turbidity.
