Binary high pressure gradient Streamline system in PEEK version, consisting of two P1m+P1s pumps with programmable mixing of two mobile phase components at high pressure with 0.1% accuracy (between 10% and 90% mixing ratios).

An integrated two-channel degasser is a recommended part locvated on the top in the solvent cabinet. In the analytical version, the flow rate range from 0.001 ml/min to 10 ml/min is adjustable to 0.001 ml/min accuracy with a maximum working pressure of 35 MPa (5,000 psi). Flow rate adjustment accuracy is ±1% and flow rate variation is better than ±0.1%. A unique feature is an active piston and seal rinse that prevents crystallization of buffers.
A touch screen display on the front panel allows intuitive control of the pump. The display shows the flow rate. A PRIME function is also directly available for flushing at increased flow rates. A cabinet is included for placing bottles with mobile phases. Control and programming of the gradient is done from the Clarity data station.
Watrex: Streamline™ Binary High Pressure Gradient system, PEEKPUMP FEATURES
- Each pump has a single stepper motor driven, dual head positive displacement pump (pump heads 180° out of phase)
- PEEK pump heads and fluid path
- Incorporates a diaphragm-type pulse damper, which reduces pulsation in the system by as much as 90% and includes an isolated pressure transducer (i.e., the transducer adds no dead volume).
- Ruby/Sapphire Check Valves (1/16” ball)
- Front panel flow adjustment in 0.001 mL/min increments
- Upper and Lower Pressure Limits: Automatically turns the pump OFF if the system pressure exceeds the maximum pressure limit, or drops below minimum pressure limit
- Microprocessor advanced control with advanced pre-compression algorithm and user calibration feature
- Back panel USB communications port for complete control and status monitoring; Clarity Driver available
- Automatic piston wash (self-flush)
