The NK200-2N Sample Concentrator is a high-efficiency nitrogen evaporator designed for rapid and gentle concentration of multiple biological or chemical samples simultaneously. It uses precisely controlled streams of nitrogen gas combined with heating blocks to speed up solvent evaporation in test tubes, vials, or microtubes—without compromising sample integrity. The unit features dual independent control zones, allowing different temperature and time settings for each block, which significantly improves flexibility and throughput. The fine stainless steel needle manifolds evenly distribute nitrogen gas to each sample position, ensuring consistent drying while minimizing solvent loss and cross-contamination. With a digital LCD interface, the NK200-2N offers intuitive control over temperature, time, and gas flow. It is widely used in pharmaceutical, biochemical, clinical, and environmental laboratories for sample prep before LC, GC, and HPLC analysis.
