This data sheet describes the features and performance of the Varian 212-LC liquid chromatography pump.
The Varian 212-LC chromatography pump is a binary pumping system designed for stable and reliable analytical LC/MS applications. It is engineered to provide accurate, smooth flow with low delay volume, making it ideal for gradient and isocratic applications up to 2 mL/min. The pump is compatible with a range of column sizes, from 1 mm to 4.6 mm, and is suitable for environmental samples, small molecule pharmaceuticals, and industrial process samples.
This document outlines the pump's key features, including self-priming check valves and MS Workstation control for full integration. It provides technical specifications such as flow rate precision, gradient composition accuracy, and maximum pressure limits. The leaflet also includes experimental conditions demonstrating the pump's performance and ordering information.
