主要特点

These bottletop dispensers conserve reagents with a built-in recirculation valve allowing you to prime and purge without waste. The PTFE piston with ETP o-ring provide frictionless movement reducing the occurrence of bubbles in your dispenses. The springless PTFE valve manifold offers superior chemical compatibility and resists jamming.
