Introduction :
CM200 visual nitrogen blowing instrument is mainly used in the preparation of large quantities of sample concentration , such as drug screening, hormone analysis, preparation of liquid, gas and mass spectrometric analysis of samples.
Working principle : The sample was heated by nitrogen gas was blown surface , so that the rapid evaporation of the solvent in the sample , the separation , so as to achieve an oxygen-free sample enrichment purposes , holding the sample is more pure . Using nitrogen blowing instrument instead of the usual rotary evaporator concentrate , concentrate dozens of samples simultaneously , so that the sample preparation time is much shorter , and time-saving , easy to operate, fast characteristics
Features :
1, the heater so that the sample is rapidly heated to the evaporation temperature , while the gas by the gas needle blow to the solution surface , prompting rapid evaporation and sample concentration solution .
2 , the gas needle position can be changed in the gas chamber , making it suitable for different tubes . Standard gas needle length is 150mm. 3, the gas chamber height can be adjusted , this model has a unique product characteristics : The sample concentration can be observed at all times concentrated liquid sample position .
4 , there are 12 gas control switch , and each pin can be independently controlled purge , purge can individually separate flow regulator can adjust the size of the gas until the close , do not waste gas.
5 , in the concentration of toxic solvents , the entire system can be placed in a hood.
6 , built-in over-temperature protection device , automatic fault detection and alarm functions.
7, LED display, simultaneous display of temperature , decreasing the time display , easy to operate .
8 , standard with air chambers and a dedicated adjustable stand
9. Heat uniform , rapid heating
