The Ultra-Chem 90 Semi Automatic Biochemistry Analyzer is designed for precise biochemistry testing, offering real-time colored graphs and absorbance readings. It features a Windows Embedded Compact 7 operating system and a 4.3-inch true color touch screen for intuitive operation. The analyzer allows for 300 programmable tests and stores up to 1,000 results with editable patient information, all powered by an external universal power supply adaptor. The unit employs photometric analysis with an interference filter, offering an absorbance range from 0.0000 to 3.0000 with a linearity of +1% and repeatability of 0.001. Its spectral range is selected automatically via a filter wheel, supporting wavelengths of 340, 405, 505, 546, 578, and 630 nm including two free positions. The device is equipped with a long-life tungsten halogen lamp acting as a light source and a photodiode detector for accurate measurements.
