Small-size high-pressure syringe-type pump for Isocratic and gradient analysis systems - No pressure pulsations during eluent feed
- Gradient system consisting of several (up to three) pumps
- Possible use of aggressive, viscous, or hot liquids by virtue of the use of special materials in the parts of the hydraulic system wetted by a mobile phase
- Fast filling and emptying the working chamber (in less than 2 min)
- Possible operation in the pseudo-continuous flow mode (2 pumps)
- Small size
- The pump is controlled by a built-in microprocessor using a keypad and display on the pump panel, or by an external PC
