Introduction:        

    Graphite tube quality directly determined AAS testing efficiency and accuracy.

After years development, we successfully produced kinds of graphite tubes for different brands AAS in the world. Our tubes are resistance, thermal character. It uses qualified graphite as basic material, after special technical treatment to produce. Our graphite tube have high sensitivity, high accuracy, good reproducibility, longer lifetime characters. Very competitive price.

Quality could reach big brands in the world.                     

* Qualified material

* Accurate grinding
