NEWMEEN SERIES NITROGEN BLOWING INSTRUMENT

Product model: NMDC-12 / NMDC-24 / NMDC-96

A nitrogen blowing instrument, also known as a nitrogen evaporator, is a specialized laboratory device designed for the purpose of concentrating or evaporating samples using a stream of nitrogen gas. This instrument is commonly employed in various scientific disciplines such as chemistry, biochemistry, and analytical chemistry.

The nitrogen blowing instrument operates by introducing a controlled flow of high-purity nitrogen gas onto the surface of a liquid sample, typically held in a sample container. The nitrogen gas serves to gently evaporate the solvent, leaving behind a concentrated residue of the analyte of interest. This method is particularly useful in sample preparation for analytical techniques such as gas chromatography (GC) and mass spectrometry (MS), where the removal of solvents is crucial for accurate and sensitive analysis.

Key features of nitrogen blowing instruments often include adjustable gas flow rates, temperature control, and compatibility with a range of sample containers. These instruments are valued for their efficiency in rapidly reducing sample volumes, enhancing the analytical sensitivity of downstream techniques, and facilitating the preparation of samples for a wide array of applications in research and quality control laboratories.

Product description:

NEWMEEN series nitrogen blowing instrument is a high-precision temperature control instrument formed by the combination of microcomputer processing and PID control mode. Its working principle is to blow nitrogen gas to the surface of the heated sample quickly, continuously and controllably, according to the evaporation speed of the concentrated solvent and Boiling point, set the heating temperature to achieve rapid concentration of a large number of samples. The instrument uses an aluminum heating module, which has good heat transfer and uniform heat transfer, can achieve rapid heating and rapid temperature control. Nitrogen is blown onto the surface of the sample to achieve anaerobic concentration of liquid samples.

Product features:

1. The gas needles are independent of each other and will not cause cross contamination. 

2. The flow rate of each air needle can be adjusted individually.

3. Each blowpipe channel can be used in combination or alone.

4. Each air needle flow regulating valve is vertically corresponding to the hole position of the module, so that the adjustment is intuitive and convenient.

5. The system has high temperature control precision, wide temperature control range and convenient temperature calibration.

6. The lifting mechanism has a safety protection device, which is safe to use.

7. The lifting mechanism has a scale display, and the positioning is accurate and clear.
