This model of the instrument is based on "Liquid Gating Technology," capable of outputting interaction information at solid/liquid/gas or solid/liquid/liquid multi-phase interfaces in the form of pressure. The instrument integrates fluid transport channels that detect pressure, providing real-time pressure output signals. As a basic version of the Liquid Gating Pressure Threshold Testing Analyzer, the GIFT-002B model features an open operation mode, allowing users to configure the output ports of the instrument according to specific experimental requirements and usage scenarios, thus building target research system models. It is suitable for integrated scientific research and industrial applications.
