What is lateral flow reader engine | Lateral flow reader engine series THETA®
Lateral flow reader engine is ...
The C16171 series lateral flow reader engine consists of an optical head for detecting reagent color development and fluorescence lines and a control board integrated with a motor for driving the optical head.
This lateral flow reader engine detects lines with high sensitivity by utilizing software programs for profile data acquisition and waveform analysis.
When developing a lateral flow reader, this lateral flow reader engine will serve as the core component specially optimized for reading of lines.
C16171 series operation sequence
1. Set an immunoassay reagent (lateral flow test strip) in the measurement area of the lateral flow reader engine.
2. Scan the detection window of the test strip.
When the lateral flow reader engine receives a measurement start command, the optical head starts scanning the reagent colordevelopment (fluorescence) area.
One measurement completes in about 12 seconds.
