THE PRODUCT DESCRIPTION ►∣Product Description:

The Chuan Yi Instrument全自动氮吹仪 is essential in a multitude of analytical tasks, particularly in environmental pollutant and food safety analysis fields, where trace target components must be obtained. Pre-treatment of the samples is required, which typically includes steps such as extraction, concentration, purification, and re-concentration. The rapid and non-destructive concentration process is a critical aspect. Common equipment used to complete the concentration process includes rotavap systems, K-D concentrators, and nitrogen吹扫 (commonly abbreviated as nitrogen blowers). Nitrogen blowing concentration is relatively simple, requiring no special device design, and is very convenient when the sample quantity is small or the solvent volume is low. However, when a large volume of samples needs to be concentrated simultaneously with a significant solvent volume, the above concentrators may fall short, making the process time-consuming and labor-intensive (requires supervision to prevent evaporation) and the open nitrogen blowing devices can be harmful to the operator's health.

The nitrogen blow-out instrument employs a special concentration method to significantly enhance concentration speed. Simultaneously, the device uses an integrated exhaust fan to direct the evaporated waste gases out through the exhaust pipeline, allowing the nitrogen blow-out concentration unit, which was originally required to be placed in a fume hood, to be safely installed on a standard laboratory platform. Not only is it easy to move and cost-effective for the lab, but it also reduces the harm to operators from toxic and harmful solvents. It is an essential pretreatment device for the laboratory.

THE MAIN CHARACTERISTICS

1. Simultaneously concentrate one or more samples without human supervision: The fully automatic nitrogen concentrator employs multiple optical sensors to monitor the concentration process of each sample. When the evaporation concentration reaches the preset volume, the system automatically stops the nitrogen blowout in the corresponding channel and triggers an alarm. The entire concentration process requires no human oversight.

2. 7-inch large LCD touch screen control, capable of handling 1-12 large capacity samples (up to 200ml)

3. Heat is applied using a dry method to prevent water vapor contamination of the samples, ensuring their safety and accuracy.

4. The heating module is made of pure aviation aluminum, offering fast and even heating with the ability to be easily replaced.

5. Special airflow sweeping path and cushioning design: Accelerates solvent evaporation and concentration, prevents solvent splashing and loss.

6. Flexible setup, control, and real-time display of operating parameters: Key operating parameters such as nitrogen blowing pressure, temperature, and working time can all be set as required.

7. Sample Non-Pollution Influence: All airways and related components are made of verified zero-pollution materials to prevent contamination from the instruments affecting the samples.

8. 12 independent throttle valves ensure air tightness in the gas line, while spiral gas needles (replaceable) accelerate concentration rate, significantly reducing nitrogen consumption.

9. Equipped with a hydraulic double-sealed door mirror protection system and an internal circulating fan system, ensuring no volatile substances leak.

10. Easy to operate and safe: Flexible working parameter settings, convenient sample insertion/extraction process, easy to learn and use; fully enclosed design and the powerful exhaust system built into the instrument effectively prevent the impact of steam and organic volatile components on the instrument and operators.
