SINNOWA DS-161 Fully Automatic Biochemistry Analyzer

Product Overview

The SINNOWA DS-161 is a fully automatic random-access biochemistry analyzer engineered for small-to-medium-sized clinical laboratories, hospitals, pet clinics, and research institutes requiring reliable, high-throughput automated chemistry testing. Manufactured by SINNOWA Medical Science & Technology Co., Ltd. under ISO 9001:2015 and ISO 13485:2016 certifications, the DS-161 delivers a throughput exceeding 160 tests per hour through a direct-reading optical system and advanced post-spectroscopy design. The analyzer accommodates 40 sample positions including standard, quality control, and emergency slots, with original test tubes and serum cup compatibility, and supports 42 reagent positions in standard configuration (24 R1 plus 18 R2) with a 2-8 degrees Celsius reagent refrigeration system. Its intelligent liquid-level detection, anti-collision protection, volume-tracking reagent probe, and automatic sample dilution/retest functions minimize manual intervention while maximizing result accuracy. The DS-161 supports endpoint, kinetic, fixed-time, single-wavelength, bichromatic, immunoturbidimetric, serum blank, single-standard, and multi-standard methodologies across a wavelength range of 330-850 nm. With AI-enabled software, multi-language support, automatic maintenance functions, an emergency sample priority channel, and storage for over 2 million patient records, the DS-161 combines compact dimensions with the performance typically expected from larger floor-standing chemistry analyzers.
