The MaxSignal® 4303 Photometer is an absorbance reader for examining histamine contamination by measuring absorbance at 450 nm. The MaxSignal 4303 Photometer is a compact, PC-controlled, photometer system designed to read and calculate the results of assays. This photometer is optimized for use with the MaxSignal® Histamine Enzymatic Assay Kit.
The MaxSignal 4303 Photometer offers 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 customize protocols.
This reliable, proven solution offers sensitivity and ease of use making it ideal for multi-user environments.
Software is included on a CD.
