High Pressure Pump: CE4100

The Adept high-pressure pump is a dual piston design, as are the Q-Adept pumps. Stepper motor drive provides superb flow precision. Software drive compensation is used in all Cecil pumps to reduce pulsing to negligible levels, without the need for mechanical pulse damping.

Flow rates from 0.001 to 10µL/min are selectable in 0.001 steps at pressures up to 40MPa. Over and under pressure protection is provided.

The pump heads have ceramic inserts for bio-compatibility with check valves of ruby and sapphire.

Binary Low Pressure Gradient Pump:
CE 4100-2

Similar to the Q-Adept Quaternary pump, this pump has just two channels for low pressure mobile phase mixing. It may also be used for isocratic operation.

All pumps may be operated from their keypads and LCD screens or from a PC work station using the Cecil PowerStream software.

Quaternary Low Pressure Gradient Pump: CE 4100-4

The Q-Adept Quaternary pump is designed using all the years of experience of the Adept pumps, delivering mobile phase to the column at flowrates between 0.001 and 10mL/min at pressures up to 40MPa.

Quaternary low pressure mixing is provided by proprietary high speed mixing valves of proven performance and reliability. A dynamic mixer is used following the pre-mixing chamber for ultimate gradient performance. These all form part of the pump and are readily accessible without removing covers.

The uncluttered design of the pump is shown here.

Semi-Preparative Pump: CE 4150

The dual piston pump has stepping motor drive like the analytical version.

The pump provides flow rates from 0.001 to 50mL/min at pressures up to 15MPa and the pump head is biocompatible.
