ST-24 Water Bath Nitrogen Blower, Process 24 Samples, Shanghai Huxi Industrial CompanyLimited (CAT#: STEM-GLE-4090-LGZ)

Sample concentration is a concern in every chemical laboratory. In the past, the rotary evaporator was mainly used for concentration. However, the use of rotary evaporator for concentration has obvious disadvantages: the concentration speed is slow, the operation is troublesome, and it is especially not suitable for small samples. In this case, the ST series nitrogen blowing instrument came into being, which not only solved all the shortcomings of the rotary evaporator, especially for small and multiple samples, but also became a must-have instrument for every chemical laboratory. For samples that cannot be heated or even need to be cooled and concentrated, they can only be concentrated using a nitrogen blower. The nitrogen blower independently developed, designed and produced by our company adopts the purging and trapping technology, and at the same time, the sample can be heated under temperature control, and the inert gas such as nitrogen can be used to quickly, controllably and continuously blow it onto the surface of the sample to achieve rapid oxygen-free sample solution. concentrate. The method is time-saving, convenient and accurate.

1. Each gas needle channel on the distribution chamber can be used in combination or individually, and each gas needle can be switched on and off independently. The height of the distribution chamber can be adjusted as required.
2. Each gas flow can be adjusted individually to meet the different needs of users. At the same time, it overcomes the weakness that the air flow of each gas path of the non-adjustable nitrogen blower is different. The unique self-balancing suspension lifting system with clever design makes the height adjustment of the distribution room more flexible.
3. Digital temperature controller, double digital display, PID technology is adopted for adjustment and over temperature alarm can be realized.
4. The parts that may come into contact with the solvent are made of 316 stainless steel, which has a long service life and is easy to clean; the whole machine can be put into a fume hood for use.
5. Each model can be equipped with gas flow meter and pressure regulating valve.
6. The standard size of the test tube rack is φ15mm in diameter, and users with special specifications can pre-order its special aperture and arrangement in advance.
