AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 1100 Series G1312A pump is a versatile high-performance microflow pump designed for critical applications in areas such as chromatography and scientific instrumentation. The pump is lightweight, compact, and easy to operate, making it ideal for a variety of lab settings. The G1312A utilizes high-pressure, direct-drive rotary devices to achieve maximum accuracy and precision. The rotating pumphead is driven by a permanent-magnet synchronous motor which allows for smooth, consistent operation and speed accuracy. The motor is also highly efficient, ensuring maximum performance. A gas-purged bearing design further adds to the pump's performance by providing increased durability and life expectancy. The G1312A features a wide range of speed and volume control options to accommodate a variety of experiment requirements. The speed can be adjusted from 20 to 1300 RPM while the flow rate is adjustable from 0 to 1100 mL/min. An integral pressure sensor allows for direct measurement of system pressure while a keypad allows for easy adjustment of the device's settings. The G1312A also features advanced safety features, including overpressure and over-temperature protection. The pump has an alarm function which activates in the case of an internal failure, preventing unwanted pressure buildup. The pump also includes ten memory locations which simplify parameter storage, saving time and allowing for more efficient operation. The G1312A is constructed from durable stainless steel, ensuring that the device is corrosion and temperature resistant and vibration tolerant. The pump is also equipped with a digital, five-digit LCD display which makes it easy to view and understand the pump's settings and running conditions. Overall, HP 1100 Series G1312A pump is an excellent choice for a variety of high-precision applications. The pump offers excellent performance, accuracy, and reliability, making it perfect for laboratories that demand precision and repeatability.
