Dry nitrogen blowing instrument Mainly used for the enrichment or preparation of bulk samples (such as drug screening, hormone analysis, liquid chromatography, and mass spectrometry in sample preparation) . By using the microcomputer control technology, the use of high pure aluminum material as the heating medium, to achieve more accurate temperature control, temperature control range. Its working principle is through the surface nitrogen blowing heating of the sample, the rapid evaporation, solvent in the sample separation, so as to achieve the purpose of keeping concentrated anaerobic samples, sample more pure.
Shanghai Chi Tang 12 dry nitrogen blowing instrument XDN100-1 Main features:
One Blow needle, independent of each other, to avoid cross contamination.
Two LED, display, time display temperature decreasing synchronous display, simple and convenient operation.
Three , Dry nitrogen blowing instrument A complete airway control switch, separate flow regulation, no waste gas.
Four In the toxic solvent concentration, the system can be put in the ventilation cabinet.
Five And the chamber height can be adjusted, the standard gas needle length is 150mm.
Six The built-in over temperature protection device, automatic fault detection and alarm function.

Comparison of dry nitrogen blowing instrument and water bath nitrogen blowing instrument
Dry nitrogen blowing instrument and water nitrogen blowing instrument is the two common nitrogen blowing instrument, the difference between them reflected in the temperature range of the heating module, and the scope of the different.
(1) The heating module
Dry nitrogen blowing instrument is used for heating the metal module, general aluminum module.
Water is the water bath heating nitrogen blowing instrument.
(2) Heating temperature range
The heating temperature range of the dry nitrogen blowing instrument at room temperature to 150 degrees.
Water bath heating temperature range of nitrogen blowing instrument at room temperature to 100 degrees.
(3) Applicable scope
For a very afraid of water samples, can not use water nitrogen blowing instrument, can only use dry type.
(4) Heating characteristics
Compared with the method of hot water bath heating mode, heating more moderate, more uniform.
(5) Sample cooling
When the special samples can not be heated, but need to be cooled, water bath water bath can be used as a way to use the ice bath.
