The 401U/D1 pump provides single or multiple channels for precision metering between 0.01 mL and 120 mL per minute. The ultrasmall footprint design and manual and auto-analog speed control and remote switching options of the 401U/D1 allow for use in applications where space is at a premium.
    The 401U/D1 provides low pulsation, and an offset L head is available for pulse-free pumping. The pump is fitted with a 400 D pumphead with a quick-release spring-loaded track, a four-roller rotor, and an adjustable occlusion lever for precise control of flow and pressure. The 401U/D1 holds a constant vacuum at low flow for error-free experiments. The infinite occlusion setting allows for the use of fine tubing.
