NG-Mini 迷你氮吹儀

NG-Mini MINI Sample Concentrator  

產品簡介

NG-Mini迷你氮吹儀主要用于樣品的濃縮或制備（如藥物篩選、激素分析、液相、及質譜分析中的樣品制備）。工作原理：通過將氮氣吹入加熱樣品的表面，使樣品中的溶劑快速蒸發、分離，從而達到樣品無氧濃縮的目的，保持樣品更純凈。使用氮吹儀代替常用的旋轉蒸發儀進行濃縮，能同時濃縮多個樣品，省時高效。

The nitrogen sample concentrator NG-Mini is mainly used for concentrating or preparing sample in batch. Such as drug screening, hormone analysis, liquid phase and mass spectrometry in the analysis of sample preparation. It works by blowing nitrogen in the surface of sample which is being heated to accelerate evaporating and separating the solvent in the samples without oxygen. Instead of the rotary evaporation instrument, nitrogen sample concentrator can efficiently concentrate dozens of samples simultaneously.

產品特點：

1、獨特的氣路控制專利設計，增強氣密性減少漏氣隱患；操作簡單，提起/按下氣針即可實現通道開關；每個通道的開關狀態一目了然。

2、加熱器使樣品被快速加熱至蒸發溫度,同時氣體經氣針吹至溶液表面，促使溶液快速蒸發和樣品濃縮。

3、氣室組件高度可以調節，使之適用不同的試管，標準氣針長度為150mm。

4、有6個氣道控制開關，不浪費氣體。

5、在濃縮有毒溶劑時,整個系統可置于通風柜中。

6、內置超溫保護裝置，自動故障檢測及報警功能。

7、顯示屏同步顯示溫度、時間，操作簡單方便。

8、標準配備氣室組件和專用可調節支架。

1. Synchronously working with heating by dry bath in the bottom and nitrogen blowing on the surface accelerates liquid evaporation and sample concentration.

2. The position of gas needle in air chamber plate can be adjusted to suit for different types of tubes.

3. The height of the air chamber plate can be adjusted. The length of a standard gas needle is 150mm.

4. Separately blow of 6 needles and flow regulating of each needle are available to avoid gas waste.

5. The entire equipment can be put into ventilation cabinet when the concentration sample in toxic solvents.

6. Built in overheat protection, automatic fault detection and fault beep alarm devices.

7. LED displays immediate temperature and diminishing time. Operation is simple and convenient.

8. Standard configured air cavity and adjustable bracket.
