High positioning accuracy – High-precision stepper motors combined with world-class guide rails ensure near "zero deviation" positioning accuracy.
Reliable embedded control – A highly integrated 32-bit STM32 microcontroller with SPI and I2C bus technology reduces board size, minimizes component count, and improves system reliability.
Intelligent system – Fully automatic power-on self-test and preparation functions detect circuit and mechanical faults immediately, while complete system purging ensures excellent experimental repeatability.
Versatile injection modes – Supports three injection modes (full loop, partial loop with loss, partial loop without loss) and multiple sample tray configurations (120-well standard, 96-well, 72-well optional) to meet diverse application needs.
