Sample concentration is a problem that every chemical laboratory has to deal with. In the past, the rotary evaporator was mainly used for concentration, but the disadvantages of using a rotary evaporator for concentration are obvious, the concentration speed is slow, and the operation is troublesome, especially not suitable for small samples. Here Under such circumstances, the Nitrogen Evaporator came into being. It not only solves all the shortcomings of the rotary evaporator, especially for small and multiple samples, but also becomes a must-have instrument for every chemical laboratory. For those that cannot be heated, they even need to be cooled. Concentrated samples can only be concentrated using a nitrogen blower. Our company independently developed and designed the nitrogen blower. , controllable, and continuous blowing to the sample surface to achieve rapid anaerobic concentration of the sample volume. This method is time-saving, convenient, and accurate. It is widely used in food safety, medicine, pesticide residue detection, clinical pharmacokinetics and other fields.
1. The air needle channels on the distribution chamber can be used in combination or individually, and each air needle can be opened and closed independently. The height of the distribution chamber can be adjusted as needed.
2. The gas flow rate of each channel can be adjusted independently to meet the different needs of users. At the same time, it overcomes the weakness of the non-adjustable gas flow rate of each gas path of the Nitrogen Evaporator. The unique self-balancing suspension lifting system is ingeniously designed to make the height adjustment of the distribution room more flexible.
3. Digital temperature controller, double digital display, adjustment adopts PID technology and can realize over-temperature alarm.
4. The parts that may be in contact with solvents are made of 316 stainless steel, which has a long service life and is easy to clean.
5. The whole machine can be used in a fume hood.
6. Each model can be equipped with gas flow meter and pressure regulating valve.
7. Generally, the standard test tube rack has a diameter of φ15mm, and users with special specifications can pre-order their special aperture and arrangement.
