Agilent 1100 HPLC G1361A Preparative Pump

The Agilent 1100 HPLC G1361A Preparative Pump is an isocratic high-performance pump with two parallel pistons, perfect for scale-up work, for typical preparative HPLC and for purity checks. This is a cam driven pump, with fixed stroke and two parallel pistons, each with (identical ball and seat) inlet and outlet valve. Each of the two pump pistons can deliver a maximum of 50 ml/min flow at up to 400 bar pressure. The two cams have overlapping delivery cycles. Compression losses are calculated, and smooth delivery is ensured through variation of the motor speed over the pump cycle. The pistons are guided through two seals each. The gap between those seals is connected to capillary fittings, this way seal wash is not only an option, but an integral part of every pump. A peristaltic pump, to automate seal wash, is also part of the system.

The pump flow leaving the pump head passes through the multi-assembly, which combines the flow of the two pistons, filters the solvent and contains a pressure sensor to monitor system pressure. No hydraulic damper is included in the system. This makes very fast gradients possible. From the multi-assembly the flow is routed to the purge valve and from there either directly into waste or on to the next module (normally injection valve or sampling device). Gradients are formed with two combined pumps, as high-pressure gradients. The combined flow is flowing through a passive mixer, to smooth composition. With its high-pressure mixing principle gradient systems and the usually high flow rates, no degassing of solvents is necessary.

All of our equipment is fully tested to perform at factory specifications before being shipped.
