Brief introduction:

HNDK200-2 blowing nitrogen is mainly applied to the mass concentration of sample preparation, such as the hormone drug screening, analysis, liquid phase and gas phase and mass spectrometry analysis of sample preparation.

Working principle: by blowing nitrogen into the heating the surface of the sample, the sample of the rapid solvent evaporation, separation, so as to achieve the sample without oxygen enrichment

The purpose of, keep sample more pure.

Using nitrogen blowing instrument instead of the commonly used rotary evaporation instrument for enrichment, can enrichment dozens of samples at the same time, sample preparation time was shortened, and

To save time, easy to operate, fast characteristic.

Features:

1. The heater to make samples were heated to evaporation temperature quickly and efficiently, and at the same time by gas cavity bullishness of needle blow to the surface of solution, promote the fast evaporation and solution

The sample concentration

2. There are 12 airway control switch, do not waste gases

3. The whole working system is composed of adjustable gas cavity and heater

4. Gas injection in the position of the chamber can be changed, so is suitable for various tube. The standard gas needle length is 150 mm

5. Chamber can be adjusted according to the solvent liquid level height, when the concentration of toxic solvents, the whole system can be placed in ventilated compartments

6. Automatic fault detection and alarm function

7. Standard gas cavity and special adjustable bracket

8. The built-in overtemperature protection device

9. The real-time temperature display, time decreasing
