VICI Valco’s says that its Cheminert C72 ultra-high pressure UHPLC injectors, switching valves, and selectors are ideal for high speed, high throughput techniques which demand a valve and fitting system that minimize internal volume and eliminate dead volume.
This injector features a proprietary stator coating that permits pressures up to 15,000 or 20,000 psi suitable for the most demanding analytical techniques. All models are compatible with any VICI actuation option such as the Cheminert C2 series HPLC injectors.
The optional microelectric actuator determines accurate positioning without limit switches or customer adjustment. Computer control is facilitated via RS-232 or RS-485 interface, but it can also be controlled manually. The actuator is CE-certified, and includes an autosensing 110/230 VAC to 24 VDC universal power supply. Compact and lightweight, the device is available in 4, 6, 8, and 10 port configurations, and choice of .004”, .006” or .010” bore.
The company has also announced a new universal valve actuator, which permits the use of a single motor and control software to operate virtually any Valco or Cheminert rotary valve, both two position and multiposition. This reduces cost and minimizes the amount of equipment necessary to provide adequate valve automation.
