LD036PFT4D – LD Class 36 mL/min 5,000 psi; PEEK; Self-flush; Pulse dampener w/ Pressure sensor; Organic seal (FP); Inlet (1/8" OD flex tubing); Outlet (1/8" OD flex tubing)


SKU: LD036PFT4D Categories: ,


Part Number: LD036PFT4D

The versatile LD Class consists of dual-headed positive displacement piston pumps delivering unmatched performance for analytical flash and small-scale preparative chromatography applications. With the patented SSI low dead-volume Pulse Dampener advanced cam technology and dual piston mechanism the LD Class provides virtually pulse-free operation.

The pumps are designed for high flow rate accuracy and low pulsation required for Analytical Liquid Chromatography (HPLC). Standard fluid path materials are Stainless Steel and PEEK in addition to optional Titanium. Other available features include jacketed heads for temperature controlled processes. With 12 mL/min 24 mL/min 36 mL/min and 100 mL/min versions reaching pressures up to 10000 psi these pumps will meet the performance requirements of demanding HPLC needs.

The high performance linear cams along with automatic pressure compensation provide precise flow rates for very accurate high pressure and low pressure gradients. Standard features include an integrated Prime-Purge Valve Pulse Dampener interactive keypad control and complete PC control and status through RS-232 and Micro USB 2.0 ports. The LD Class provides the precise flow and low pulsation for the most challenging separations.
