The 400F/D peristaltic pump generates flow rates up to 82 ml/min and works well in applications that require lower flow rates. The pump uses a spring-loaded track for long tube life and flow-accuracy. When necessary, the tubing occlusion can be adjusted to produce higher pressures. Available with four standard gear motors, the pump accepts tube elements with a 1.0-mm wall thickness, and it comes in four bore sizes to match the pump to the required flow. The unit also comes in two and three-channel models.
