Multi Functional Nitrogen Blowing Concentrator

Product Description of Products

The multifunctional nitrogen blowing concentrator is widely used in analytical work, especially in the fields of environmental pollutants and food safety analysis. In order to obtain trace amounts of target components, it is necessary to preprocess the prepared samples. The process mainly includes basic steps such as sample extraction (extraction), concentration, purification, and re concentration. Among them, how to quickly and non destructively concentrate is also a key step. The commonly used devices for completing the concentration process include rotary evaporators, K-D concentrators, and nitrogen blowers (referred to as nitrogen blowers). Among them, nitrogen blowing concentration is simple and does not require special device design. When the sample quantity is small or the solvent amount is small, this method is convenient to use. When a large amount of samples need to be concentrated at the same time and there is a high amount of solvent, the above concentration devices become inadequate, and the concentration process becomes time-consuming and laborious (requiring supervision to prevent drying), and the open nitrogen blowing device is not conducive to the health of operators.

This device adopts a unique concentration method to significantly improve the concentration rate. At the same time, the equipment uses its own exhaust fan to directionally discharge the evaporated exhaust gas through the exhaust pipe, allowing the nitrogen blowing concentration device, which originally had to be placed in a ventilated kitchen, to be safely installed on a general experimental platform. Not only is it easy to move, saving laboratory costs, but it also reduces the harm of toxic and harmful solvents to operators. It is a laboratory sample pretreatment device.

Product characteristics 

1. The multifunctional nitrogen blowing concentrator can simultaneously concentrate single or multiple samples without the need for manual monitoring: The multifunctional nitrogen blowing concentrator uses 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 blowing of the corresponding channel and gives an alarm prompt. The entire concentration process does not require manual supervision;

2. Special airflow blowing trajectory and buffering design: can accelerate solvent evaporation and concentration, prevent solvent splashing loss;

3. Working parameters can be freely set, controlled, and displayed in real-time: The main working parameters include nitrogen blowing pressure, water bath temperature, and working time, all of which can be set as needed.

4. Stable and constant nitrogen blowing airflow pressure: The instrument comes with an automatic pressure regulating device, which can automatically control and maintain a constant airflow pressure, unaffected by sudden opening, closing, or quantity of the working channel (sample);

5. No pollution impact on the sample: All gas paths and related components are made of verified zero pollution materials to avoid contamination of the sample from the instrument;

6. Easy to operate and safe: flexible working parameter settings, convenient sample insertion/extraction process, easy to learn and use; The fully enclosed design and the built-in strong exhaust system configuration of the instrument can avoid the influence of water bath steam and organic volatile components on the instrument and operators.
