The dry nitrogen evaporator, also known as a nitrogen concentrator or nitrogen purge instrument, is primarily used for the oxygen-free concentration or preparation of large-volume samples. Widely applied in pesticide residue analysis, commodity inspection, food, environmental, pharmaceutical, and biological product industries, the nitrogen evaporator employs microcomputer control technology. Heating utilizes high-purity aluminum material as the heating medium, enabling rapid heating, precise temperature control, and a wide temperature range. It can process 24 sample sets simultaneously.
Each blowing needle can be independently controlled to prevent cross-contamination.
Features more uniform overall temperature and rapid heating speed.
The instrument has an LED display showing synchronized temperature readings and a countdown timer, allowing real-time monitoring of temperature changes.
Equipped with 24 gas channel control switches for gas conservation. Each blow needle's position can be independently adjusted to accommodate different sample containers and locations.
When concentrating toxic solvents, the entire system can be placed within a fume hood to minimize hazards.
Built-in over-temperature protection, automatic fault detection, and alarm functions ensure convenience and reliability.
The instrument's gas chamber height is adjustable, with standard gas needles measuring 15 cm in length.
It offers simplified operation and achieves temperatures up to 150°C for enhanced sample concentration.
This product can also function as a standard dry thermostat.
