Varian with platform graphite tube for AAS:
Graphite tube quality directly determined AAS testing efficiency, accuracy. After years development, 
we successfully produced MA series graphite tube. It is resistance, thermal character. It use qualified
 graphite as basic material, after special technical treatment to produce. Our graphite tube have high
 sensitivity, high accuracy, good reproducibility, longer lifetime, very competitive price. 
Quality could reach big brands in the world.
 
* Qualified material
* Accurate grinding
* Fully mixture
* Proper pressure
* Correct heating treatment
* Whole process cleaning control
* Precision machining
* special coating technology 
* Strict performance quality test after produce
 
Above fully guaranteed our graphite tube quality is very high.
 
Our graphite tubes are very full to cover all the brand AAS, including:
