SperryTron 10R Plant Root and Stem Hydraulic Conductivity Analyzer / Centrifuge

-Used to analyze the water permeability of plants, which is the most effective instrument for studying the drought tolerant plants in arid regions.

-It was developed jointly with the specialist in this field Professor Melvin Thamas Tyree.

-Chinatron and SperryTron system can automatically analyze the results, reduce manpower and improve the efficiency and accuracy of the experiment.

Integrated portable temperature collector in rotor

A portable temperature collector is integrated in the rotor, which can record and simulate the freezing process of trees in nature.

Antifreeze technology of cuvettes

The antifreeze technology of cuvettes is to ensure that the stem in the water –filled cuvettes  must be delayed or even prevented from solidification when the stem is freeze under freezing injuring studying of cavity mechanism. When the stem segment is frozen, the cuvette is always kept above 0 ℃ by ChinaTron/SperryTron analyzer, so that the water can flow out along the axis.

Water injection system

The water injection system of ChinaTron and SperryTran analyzer can prevent the air or hydrophobic particles moving to the end of the rotation axis after entering the xylem conduit through the stem incision, so as to reduce the detecting error of the plant stem hydraulic conductivity.

Imaging system

ChinaTron System is equipped with an imaging system which can produce the digital picture of the cuvette liquid level. The special image processing program can calculate the moving distance of the cuvette liquid level to get the flow rate per unit time.

Integration of data collector and tabletop centrifuge

The control system of tabletop centrifuge connects speed control part, temperature control part, control unit, water injection component, auxiliary background light source of camera, human-computer interaction interface of centrifuge through the lower control panel to integrate the various circuit units in the Chinatron prototype. It improves the integration and operability of the system.
