Watson Marlow 505di Peristaltic Pump

The Watson-Marlow 505Di is a high-performance peristaltic pump designed for precise fluid handling across laboratory, industrial, and pharmaceutical settings. As a part of the 505 series, this unit is in full working condition and ready for immediate deployment. It features advanced digital control for accurate and repeatable dosing. Key functionalities include a digital display for precise speed and flow management, a flow rate adjustable from 4 microliters/min to 4.4 liters/min based on tubing size, and a speed range of 0 to 350 rpm. The pump enables high-speed dispensing, capable of delivering 100 ml in under 1.4 seconds with an accuracy of ±0.5%. It offers remote control capabilities via RS232 and the programmability to store up to 50 dispensing programs for routine tasks. The pump also allows reversible flow for easy priming and purging, and is compatible with various tubing materials such as silicone, Marprene, or Tygon to handle diverse chemicals. Its peristaltic design ensures easy maintenance, eliminating cross-contamination risks and simplifying cleaning procedures. The included 505L pumphead delivers virtually pulse-free flow through its ‘double-Y’ twin tube design, offering smooth, consistent fluid delivery with flow rates up to 4,375 ml/min, supporting both single and twin-channel flows. The non-drip function ensures precise dosing by preventing waste at the end of each cycle. Technical specifications include a voltage range of 100-220 V / 220-240 V, power consumption of 100 W, operational speed range from 0 to 350 rpm, and operating temperature between 5 to 40 °C. The unit's dimensions are 220 x 400 x 120 mm (W x D x H).
