Product Overview
The RHEODYNE MXT715-004 is a precision analytical injection valve engineered for accurate, repeatable sample introduction in high-performance liquid chromatography (HPLC) and analytical instrumentation systems. Manufactured by IDEX Health & Science under the renowned Rheodyne brand, this valve utilizes a rotary shear-valve working principle in which an internal rotor and stator pair align to switch between LOAD and INJECT positions. The MXT715-004 is a manually actuated, two-position injection valve designed for low-dispersion sample transfer, making it a critical flow-control component in analytical fluid circuits where precise volumetric reproducibility and chemical inertness are essential.
