The easy-to-use keypad controller allows you to set up and store gradient methods. A pulse damper and transducer in one of the pumps allow you to set upper and lower pressure cut-off limits to help extend column life. During operation, this Series I pump monitors the current system pressure.

The detector LED displays absorbance or lamp energy levels. Simply dial in the desired wavelength, sensitivity, and rise time on the detector; auto-zero, and you are ready to run.

The proven single-piston pump design combined with the pulse-damper give the Series I pump the performance of the most expensive pumps at a fraction of the cost.

The Series I Binary Gradient is available in stainless steel or metal-free, biocompatible Bioclean™ (PEEK) fluid path.

Pump

The Series I Pump provides precise, reproducible flows to 10 mL/min. at 2500 psi in an economical package. The pump can be used in liquid chromatography applications and for metering.

For binary gradient solvent delivery, the fluid outputs of the two pumps are combined through a tee into the pulse damper to provide effective mixing and pulse dampening characteristics.

Detector

The V520 UV-Vis detector features high sensitivity with selectable absorbance ranges from 0.0005 to 4.0 AUFS. Unique fiber optics and proprietary circuits ensure low-noise, low-drift performance. A pre-aligned deuterium lamp is standard for the UV wavelength range (195- 400nm); an optional tungsten lamp extends the detector range (400-800nm). The analog output of the detector may be hooked up to any data collection system.

Connections between the pumps and the keypad controller are easily made with the supplied RS232 cables. The System Control Unit (SCU) provides control of the gradient program, run duration, and number of repeating cycles. It can store 10 gradient methods, link to a shutdown method, and receive an external start command (TTL/contact closure) from the injector or data system.
