The 1212 solenoid valve by Keyto is a 3-way pinch valve with a service life of up to 500 million cycles, designed with special materials. Its built-in tube design reduces internal volume to 10μL, enabling ultra-micro liquid transfer with minimal cross-contamination. With a rapid response speed of under 40ms, it supports flexible liquid path switching in medical, laboratory, and industrial applications. The valve's new appearance design ensures simple and convenient installation.
