The 400F/DM is our standard instrument-quality peristaltic pump for low flow rates. The pumps have a spring-loaded track, which gives superior life and flow-accuracy. The tubing occlusion can be adjusted to produce higher pressures. The pump is available with four standard gearmotors. Each one is extremely small in size and has low power requirements. The pump accepts standard manifold tube elements, with three color-coded stops. The tubing is available in 20 bore sizes, allowing the user to precisely match the pump to the required flow. See page 21 for additional options.
