Graphite Tube

As important of graphite carbon machining parts,graphite tube is classified:

1、heating mode:portrait heated graphite tube and transversely-heated Graphite tube;

2、performance:

1)ordinary graphite tube is suitable for low temperature(≤2000℃) of atomic elements such as zinc,cadmium,lead;

2)pyrolytic graphite tube is suitable for atomic elements of low、middle、high (>2500℃) temperature;  

3)platform graphite tube is suitable for atomic elements of low(≤2400℃)、middle temperature; 

Due to different features,graphite tube has different applications,applications such as:

1、research and application of geological samples;

2、research and application of environmental samples;

3、research and application of biological samples;

4、Research and application in medicine and medical and food;

Althrough the wide applications of graphite tube,it's also important to use fairly,know the service-life of graphite tube,replace graphite tube timely,make sure the authenticity and reliability of research results.we can estimate the service-life from the following several points:

1、from the appearance;

2、the absorbance of the standard solutions;

3、reproducibility standard deviation;

4、usage counter;

5、the analysis results of peak shape;
