Mini Metering Pump LMMP-A10

The Mini Metering Pump LMMP-A10 offers a highly versatile flow rate range from 0.001 to 10 mL/min, making it suitable for both analytical and semi-preparative HPLC applications. Its precision is ensured by a double-piston pump design with an electronic pressure pulsation suppressor, which minimizes pulsation effects and guarantees smooth, stable flow. The flow rate accuracy of the pump is 0.5% at 1 mL/min, using secondary water at room temperature, while flow rate reproducibility is 0.2% under the same conditions. This high degree of control ensures reproducible chromatography results and supports experiments requiring sensitive and consistent mobile phase delivery.

The Mini Metering Pump LMMP-A10 is specifically engineered to handle corrosive mobile phases, including organic acids, organic alkalis, and inorganic acids. To minimize contamination and ensure system durability, the pump uses inert materials in all areas exposed to liquids, including passivated 316 stainless steel, PTFE, and PEEK. These materials provide chemical resistance while maintaining the purity of the samples being analyzed. The thoughtful use of high-quality, inert materials reduces the risk of secondary impurities affecting the chromatography, making this pump highly reliable for sensitive laboratory applications such as HPLC and other precision liquid delivery processes.

Yes, the Mini Metering Pump LMMP-A10 is designed for seamless integration into automated laboratory systems. It features LAN RS-485/232 communication ports, allowing control through a PC or chromatographic workstation. This enables users to program flow rates, start/stop operations, and monitor system performance remotely. Additionally, the pump has built-in maximum and minimum pressure settings for system protection, and the LCD display provides real-time monitoring of operational parameters. Its compatibility with automated setups ensures that users can perform complex and unattended HPLC experiments with consistent, precise results.

The Mini Metering Pump LMMP-A10 is ideal for use in HPLC systems, supporting both analytical and semi-preparative applications. It is commonly employed in laboratories dealing with pharmaceuticals, biochemistry, food analysis, and chemical research where precise, stable, and reproducible flow is critical. Its ability to handle corrosive mobile phases allows researchers to work with a variety of organic and inorganic solvents without risk of contamination or system degradation. The pump is also suitable for experiments requiring microflow delivery or handling sensitive samples, making it a versatile and indispensable tool for modern chromatography labs.

The Mini Metering Pump LMMP-A10 is designed with durability and low maintenance in mind. Its double-piston pump system and electronic pulsation suppressor reduce mechanical wear, while the use of high-quality inert materials prevents corrosion and contamination. Components such as the piston backflushing capillary and pump head inlet are designed for easy cleaning and maintenance, ensuring consistent performance over time. The compact design and user-friendly LCD interface make monitoring and operation straightforward, reducing the need for frequent technical intervention. Overall, the pump combines robust construction with ease of use to provide reliable and long-lasting service in demanding laboratory environments.
