[0002] A graphite digestion tube is a device used for sample pretreatment, mainly for the acid digestion process in a laboratory for subsequent analysis and determination. The graphite digestion tube plays an important role in laboratory analysis. It helps decompose the sample through the action of high temperature and acid, enabling the accurate determination of the elements to be measured in the sample.
[0003] During the test process, when the robot gripper grabs the digestion tube, if the forces on the two arc-shaped parts are slightly uneven, the digestion tube will tilt up and down, causing the error at the bottom of the digestion tube to exceed the accuracy range of the robotic arm for picking and placing (1 - 2 mm). As a result, it cannot be accurately placed into the digestion hole and the digestion rack, affecting the test accuracy and making the clamping of the digestion tube unstable.

[0006] The fastening unit includes an installation groove, which is opened on the outer side of the lower end of the digestion tube main body. An airbag is arranged on the inner side of the installation groove. A connection channel is opened in the inner side of the digestion tube main body. An inflation tube is fixedly connected to the upper side of the airbag, and a fixed tube is fixedly connected to the front side of the inflation tube.
[0007] According to the graphite digestion tube for a domestic information technology-based heavy metal digestion instrument system, the airbag is adapted to the installation groove. It is convenient to install the airbag.
[0008] According to the graphite digestion tube for a domestic information technology-based heavy metal digestion instrument system, an electromagnetic valve is arranged on the outer side of the fixed tube.
[0009] According to the graphite digestion tube for a domestic information technology-based heavy metal digestion instrument system, the left end of the fixed tube passes through the outer side of the digestion tube main body.
[0010] According to the graphite digestion tube of a system for digesting heavy metals in the context of information technology innovation, the airbag is arranged in a circular ring structure.
[0011] According to the graphite digestion tube of a system for digesting heavy metals in the context of information technology innovation, the connection channel is adaptively arranged with the fixed tube.
[0012] Beneficial effects:
[0013] By providing an installation groove, an airbag, an inflation tube, a fixed tube and an electromagnetic valve, it is convenient for the clamping jaws to clamp the digestion tube body. By controlling the inflation of the airbag, the clamping between the clamping jaws and the digestion tube body becomes tighter, avoiding slipping off.
