A dual-mode parallel concentrator combining needle-following and vortex nitrogen blowing can allow for batch quantitative concentration of samples. Each channel is independently controlled and equipped with an infrared level sensor for precise volume determination. The instrument is designed with advanced multi-way balanced gas supply structure to ensure the parallelism of batch sample concentration. Equipped with a large color touch screen, the graphical interface displays the concentration process intuitively and can monitor remotely, making it a more intelligent and efficient concentration equipment for laboratories.
