Shanghai Jingqi 12-Hole Dry Nitrogen Blower NBI-12A, Shanghai Jingqi Instrument Co., Ltd. (CAT#: STEM-GLE-2242-YJL)

Shanghai Jingqi 12-Hole Dry Nitrogen Blower NBI-12A, model NBI-12A is manufactured by Shanghai Jingqi Instrument Co., Ltd.
This product is mainly used for the concentration or preparation of large batches of samples. Through microcomputer control technology, high-purity aluminum material is used as the heating medium to achieve more accurate temperature control and a wide range of temperature control. Its working principle is to blow nitrogen into the surface of the heated sample, so that the solvent in the sample can be quickly evaporated and separated, so as to achieve the purpose of sample anaerobic concentration and keep the sample more pure.

The blowing needles are independent of each other to avoid cross-contamination.
The height of the air cavity can be adjusted, and the standard air needle length is 150mm.
The nitrogen blowing instrument has 24 airway control switches, no waste of gas.
When concentrating toxic solvents, the entire system can be placed in a fume hood.
Built-in over-temperature protection device, automatic fault detection and alarm function.
LED display, temperature synchronous display, time decrement display, simple and convenient operation.
