Microfluidic Marvel: The Seamaty SD1 Dry Chemistry Analyzer's Test Tray Workflow

This blog post dives into the fascinating world of the Seamaty SD1 dry chemistry analyzer, specifically exploring the inner workings of its test tray workflow.

Faster, Easier, More Accurate Diagnosis:

The Seamaty SD1 revolutionizes medical testing by providing on-site results using a mere 0.1cc of whole blood, serum, or plasma. This fully automated analyzer boasts built-in centrifugation, QR code compatibility, and real-time quality control, leading to faster, easier, and more accurate diagnoses within just 12 minutes.

Replacing the Bulky with the Brilliant:

Gone are the days of cumbersome biochemical machines. The Seamaty SD1 utilizes pre-packaged, lyophilized reagent kits that require no manual diluent addition. These refrigerated kits (2-8°C) offer a remarkable one-year shelf life. But how does this compact system achieve the accuracy of its larger counterparts?

Step 3: Precise Mixing (140-210 seconds)

• A combination of siphoning force and centrifugal force carefully guides the sample and pre-measured diluent into the mixing chamber.
• The instrument employs alternating acceleration and deceleration maneuvers to ensure homogenous mixing.

Step 4: Sample Distribution and Reaction (210-432 seconds)

The diluted sample is strategically distributed into designated colorimetric chambers containing various biochemical reagents.

Step 5: Colorimetric Detection and Analysis (432-672 seconds)

• Chemical reactions within each chamber commence, generating colors indicative of specific biochemical concentrations.
• The SD1 utilizes constant light source detection technology, employing a halogen lamp to ensure a stable light source with minimal intensity variations (less than 1%). This surpasses traditional xenon lamp performance.

The Power of Microfluidics and Spectrophotometry:

By seamlessly integrating microfluidics with spectrophotometry, the SD1's built-in centrifuge further enhances accuracy, adhering to Lambert's Law.
