The WATSON MARLOW 205CA series of multi-channel cassette pumps feature maximum flows up to 22 ml/min, and offer high-quality pumping with extreme precision. The pumps are available in two versions, the 205S/CA that are manually controlled, and the 205U/CA that can be either manually or automatically controlled. Both types have variable speeds and contain tachometer-controlled servo-quality DC motors. These pumps are integrated with 0-5V DC tachometer output for speed monitoring, and 5V auxiliary output for motor run indication.

The two series also feature a keypad lock for protection. Each channel's flow rates are controlled by a multi-turn "click-stop" pressure adjustment option. The 205CA pump head contains sprung track and snap-fit cassettes, and is a standard choice for various general applications. 205CA pumpheads can accept manifold pump tubing in six different materials with nineteen different sizes. Additional functions include TTL control, optional voltage, remote low voltage option etc.
