1 Introduction

1.1

General

Pump P-960 is a compact single-channel pump for use in liquid
chromatography and other applications where constant flow rate is
required. In ÄKTA

™

design chromatography systems, it is used as a

sample pump.

Pump P-960 features:

•

Operating pressure up to 2.0 MPa (20 bar, 290 psi).

•

Flow rates up to 50 ml/min.

•

A pressure sensor connected to the pump outlet.

•

Interface for connecting an air sensor directly to the pump.

Pump P-960 works with a wide range of columns and media supplied
by Amersham Biosciences.

The pump is controlled from a PC running UNICORN

™

control

system, version 4.12 or later.
