Piston pump ECP2300

waterelectricself-priming

Preparative HPLC pump with flow-rate ranges of 0.001 – 300 ml/min Powerful and durable pumps suitable for preparative applications in low- and high-pressure liquid chromatography across the chemical industry. An extended number of wetted material versions – not only stainless steel but also Hastelloy, titanium, and PEEK. ECP2300 is designed with 2 pump heads connected in parallel with a piston diameter of 3/8”. Many improvements make these pumps more reliable, including a new learning algorithm for pulsation suppression and a leakage sensor. The pumps can operate in two modes, i.e., using constant pressure or using the newly added option of constant flow rate. Gradient function: These pumps work as isocratic pumps, and, together with ECOM gradient boxes, they also work as gradient pumps. Gradient boxes ECB2005 and ECB2005PC are equipped with a four-way gradient mixing valve and must be ordered together with the pump. These sophisticated units allow for achieving a precise low-pressure gradient, i.e. gradual changes of solvent composition by mixing up to four liquids at the pump‘s entry. The gradient profile can be defined via a computer or manually using a display and a keypad. Without the use of a gradient box, the pump works isocratically. Customers can use the pistons‘ back-washing function while working, for example, with a buffered mobile phase. Seals: All pumps are delivered with GFP (PTFE) seals by default. You can order the pumps with UHMW-PE seals, which are considered the optimal recommended choice.
