Fully Closed Dry Nitrogen Blowdown Concentrator with 50-Step Program Temp Control for Lab Sample Concentration

1. Employs dry heating technology to avoid sample contamination from water vapor, safeguarding sample safety and analytical accuracy

2. Utilizes 5 operational modes and a 50-step program temperature control system for high-level automation and precision

3. Constructed from pure aviation aluminum, the heating module offers rapid, uniform heating and supports on-demand replacement for enhanced versatility

4. Boasts 4-sided module visibility and a drawer-type sample tray for push-pull sampling, enabling unobstructed, convenient observation of sample liquid levels

5. Features two electric lifting modes for the blow needle—fine-tune and rapid lift—eliminating the need for manual adjustment

6. Integrates an automatic pressure regulation device to maintain consistent pressure across all gas pathways

7. Comes with a built-in multi-group data storage function for real-time access to device operational data

8. Incorporates a double-sealed door mirror protection system and built-in circulating fan system, eliminating the need for ventilation windows and preventing volatile substance leakage

9. Equipped with front and side observation windows on the chassis for easy monitoring of sample status throughout processing

10. Includes a nitrogen preheating function that delivers heated gas (approximately 45°C), accelerating sample concentration, preventing condensation between volatilized concentrate and blow needles, and avoiding sample contamination or cross-infection

11. Combines nitrogen preheating technology with independent throttling solenoid valve control to ensure gas path air tightness while significantly reducing nitrogen usage
