Fully Automatic Nitrogen Blow Dryer CNNS-12G Dry Heating
The fully automatic nitrogen blowdown concentrator is essential in a large volume of analytical work, particularly in environmental pollutant and food safety analysis fields, where pre-treatment of the samples is necessary to obtain trace target components. This process primarily includes basic steps such as sample extraction (extraction), concentration, purification, and re-concentration. How to quickly and non-destructively concentrate is also a very critical aspect. Common devices used to complete the concentration process include rotary evaporators, K-D concentrators, and nitrogen blowdown (shortened to nitrogen blowdown instrument), among which nitrogen blowdown concentration is relatively simple and does not require special device design. It is very convenient to use this method when the number of samples is not large or the volume of solvent is small. However, when a large number of samples need to be concentrated simultaneously and there is a large volume of solvent, the above concentration devices are insufficient, making the concentration process time-consuming and labor-intensive (requires supervision to prevent evaporation) and the open nitrogen blowdown devices are harmful to the health of the operators.
Key Features:
1. Simultaneously concentrate one or more samples without manual supervision: The fully automatic nitrogen concentrator employs multiple optical sensors to monitor the concentration process of each sample. Upon reaching the pre-set volume after evaporation concentration, the system automatically stops the nitrogen blowout in the corresponding channel and triggers an alarm. The entire concentration process requires no human oversight.
2. 7-inch large LCD touchscreen control, capable of handling 1-12 large capacity samples simultaneously.
3. Unique airflow sweeping path and cushioning design: accelerates solvent evaporation and concentration, and prevents solvent splashing and loss.
4. Arbitrary setting, control, and real-time display of working parameters: Main working parameters include nitrogen blow pressure, water bath temperature, and working time, all of which can be set as required.
5. Sample Non-Pollution Influence: All airways and related components are made from verified zero-pollution materials to prevent sample contamination from the instrument.
6, 6 or 12 independent throttle valves ensure air tightness in the gas line, while spiral gas needles (replaceable) accelerate concentration speed, significantly reducing nitrogen consumption.
7. Equipped with a hydraulic double-sealed door mirror protection system and an internal recirculating fan system to ensure no volatile emissions leak.
8. Nitrogen blow air pressure is stable and constant: The instrument is equipped with an automatic pressure regulation device, which can automatically control and maintain a constant air pressure, unaffected by the sudden opening, closing, or quantity of the working channel (sample).
9. Easy Operation and Safety: Flexible working parameter settings, convenient sample insertion/removal process, easy to learn and use; fully enclosed design and the powerful exhaust system built into the instrument effectively prevent the impact of water bath steam and organic volatile components on the instrument and the operator.
10. The fully automatic nitrogen blow-out instrument features an automatic water refilling function.
Daily maintenance and care for the dry nitrogen blow-off instrument are as follows:
After use, promptly clean the instrument's interior to remove any residual samples and protective liquids. Use the cleaning solution and ultrasonic cleaner provided in the lab to remove all residues.
2. Regularly inspect the nitrogen generator of the nitrogen blower to ensure proper operation.
Keep the instrument dry and prevent water droplets from entering the interior of the instrument.
4. Avoid excessive vibration or impact to the instrument to prevent damage to internal parts.
5. Regularly inspect the instrument's interfaces to ensure there is no looseness or detachment.
6. Regularly replace the protective film to prevent corrosion of the instrument's shell.
7. Regularly calibrate the instruments to ensure accuracy and stability.
