Introduction：
Dry Nitrogen Evaporator concentrates up to 12 samples at once by nitrogen blowing with aluminum heating and no oxygen. Widely used for pesticide residue analysis, commodity inspection, pharmaceutical and biological industries....
The dry nitrogen concentrator (nitrogen purge instrument) is mainly used for the concentration or preparation of large batches of samples under an oxygen-free atmosphere. It is widely used in pesticide-residue analysis, commodity inspection, food, environmental protection, pharmaceuticals and biological products. The nitrogen concentrator uses microcomputer control technology; heating uses high-purity aluminum as the heating medium, with fast heating, more accurate temperature control and a wide temperature-control range, and can process 12 samples simultaneously.
Each purge needle can be controlled independently, avoiding cross-contamination.
The height of the instrument gas chamber can be adjusted; a standard gas needle length of 15 cm is provided.
The nitrogen concentrator has 12 gas-channel control switches to save gas; each purge needle position can be changed independently to suit different sample containers and sample positions.
When concentrating toxic solvents, the whole system can be placed in a fume hood to reduce risk.
Built-in over-temperature protection device with automatic fault detection and alarm functions — convenient and practical.
The instrument has an LED display with synchronous temperature display and countdown time display, allowing the temperature change to be observed at any time.
More uniform overall temperature and fast heating.
The product can also be used as an ordinary dry block thermostat.
Simple to use; the temperature can reach 150℃ for better sample concentration.
