Model C72 Nanobore and Microbore UHPLC Injectors

Up to 20,000 psi liq 360 µm, 1/32", or 1/16" Valco fittings 100, 150, or 250 micron bore 4, 6, 8, or 10 ports Coated stainless stator High-strength PAEK rotor

Many of the latest analytical techniques require systems capable of pressures up to 10,000, 15,000, or even 20,000 psi. The new C72 series injectors from Cheminert feature a proprietary rotor material and stator coating that permit these pressures. C72 injectors are available in a variety of configurations, including a model incorporating our new 360 micron fittings and models with a vertical injection port. (Consult the factory for more information about vertical injection port models.)

The injectors use the same mounting system as the widely used Cheminert C2 series HPLC injectors. Our microelectric actuator determines accurate positioning without limit switches or customer adjustment. Computer control of the actuator is facilitated by TTL-compatible digital logic, contact closures, or RS-232 (RS-485 optional), but it can also be controlled manually. The microelectric actuator is CE-certified, and includes an autosensing 110/230 VAC to 24 VDC universal power supply.
