● 7-inch large LCD touch screen.

● Imported optical sensor is used for accurate constant volume, which can be accurately fixed to 0.5ml/1ml/2ml.

● 12 independent constant volume adjustment devices to ensure the constant volume accuracy of different color solvents.

● When the concentration reaches the preset volume, the system automatically stops the nitrogen purge of the corresponding channel and alarms. The alarm function can be turned off or on.

● Automatic water replenishment function, no need to add water manually and with anti-dry burning function.

● Equipped with automatic pressure regulating device to ensure the air pressure uniformity of each gas way.

● Built-in multi-group of data storage functions, operation data can be viewed.

● (Optional) built-in nitrogen preheating device, nitrogen blowing after preheating greatly improves the concentration rate, prevents condensation between the volatile concentrate and blowing needle to ensure no cross-contamination of samples.

● Spiral blow needle: 12-position independent throttle valve control ensures the air tightness of the gas path. The spiral blow needle (replaceable) speeds up the concentration rate and greatly saves nitrogen consumption.

● Heating module: dual-channel heating system, fast heating speed and high temperature control accuracy.

● Sealing: hydraulic dual sealing door protection system, built-in circulating fan system to ensure no volatile leakage.
