Product Manual Library
We have an assortment of Product Manuals at our disposal. Due to US Copyright law, manuals listed in our library are not for copy, sale and/or redistribution. These manuals are used by HiTechTrader.com to repair and service equipment. They are also utilized to make sure that the parts, accessories, and actual instruments are compatible with our customers’ needs. This is paramount when buying surplus laboratory or used analytical equipment. Specifications on equipment marketplaces, such as Ebay, can lack this essential information. Our library of manuals allows us to answer customer “needs” questions (i.e.- “Can the software work on Windows XP, Windows 7, Windows 8, or Windows 10?”).

Make : Rainin Instrument
Model : RP-1 Peristaltic Pump
The Rainin Dynamax RP-1 Peristaltic Pump is specifically designed for fluid transfer. The rotating head has ten stainless-steel rollers. As the head rotates, five of the rollers press the tubing up against the compression arm, producing flow by peristaltic action. Five rollers constantly in contact with the tubing ensures low pulsation, smooth flow, and high pressure. The Model RP-1 pump is ideal for critical liquid chromatography, gradient generation, and flow analyzer applications. The RP-1 incorporates a unique cam design: the adjustment screw does not press the compression arm directly. Instead, turning the adjustment screw in the RP-1 moves a cam which applies gradual force to the compression arm. This results in more precise flow control and reduced tubing wear. The RP-1 is powered by a high torque stepper motor, controlled by a microprocessor with unique feedback circuitry for good speed stability, even at extremely low flow rates. Speed stability is maintained between 0° - 40°C and against back-pressures of up to 5 bars. Pump speed is shown in revolutions per minute and a liquid crystal display on the pump front panel. Pump speed and decision of rotation are controlled by a membrane keypad next to the display.
