Fully Automatic Water Bath Nitrogen Concentrator with 7-inch Touch Screen & Precise Volume Control

1. Utilizes imported optical sensors for precise volume calibration, allowing accurate settings of 0.5ml/1mL/2mL

2. Equipped with a 7-inch large LCD touchscreen, the system can simultaneously process 1-12 large-volume samples

3. Boasts a dual-channel heating system that delivers rapid heating and exceptional temperature control precision

4. Features an automatic water replenishment function, along with water shortage and over-temperature alarm systems for enhanced operational safety

5. Adopts an automatic pressure regulation device to maintain consistent air pressure across all gas channels

6. Upon reaching the preset concentration volume, the system automatically halts nitrogen purging for the corresponding channel and triggers a persistent alarm, with the alarm function toggleable between on and off states

7. Incorporates an independent volume adjustment mechanism to guarantee volume setting accuracy for solvents of varying colors

8. Comes with built-in multi-group data storage functionality, enabling real-time access to machine operational data

9. Implements a hydraulic double-sealed door protection system and an integrated circulating fan system to prevent volatile substance leakage

10. Includes a nitrogen preheating function that delivers heated gas (temperature: about 45°C) to accelerate sample concentration reactions, prevent condensation between volatile concentrates and blow needles, and eliminate sample contamination and cross-infection risks

11. Combines nitrogen preheating functionality with independent throttling solenoid valve control to ensure gas path airtightness and significantly reduce nitrogen consumption
