Beijing Wuzhou Dingchuang SR series hydrothermal synthesis reactor pressure dissolution bomb

Equipment Introduction：
Beijing Wuzhou Dingchuang SR series hydrothermal synthesis reactor pressure dissolution bomb

Also known as hydrothermal kettle, high-pressure digestion tank, sample analyzer, pressure dissolution bomb, digestion tank, polytetrafluoroethylene high-pressure tank.

Wuzhou Dingchuangadvantage：
The reaction is relatively slow under standard atmospheric pressure, but it proceeds rapidly under high pressure.
Highly corrosive reagents such as HF or aqua regia can be used, which can corrode most other reaction vessels.
During the dissolution process, there will be no loss of analytical samples or trace elements. And no additional components will be added to affect product analysis.

1Strict selection of materialsThe durability and reliability of materials are crucial for the synthesis kettle, and the prices of similar materials can vary by several times. Our company adheres to the concept of professional durability, and all synthesis kettles are made of high-quality materials.
2New sealing structure designIt can ensure that the hydrothermal kettle remains sealed during continuous high temperature and cooling processes, while traditional structures may leak during the cooling process due to differences in the thermal expansion coefficient of polytetrafluoroethylene (PTFE).
3Hole type fastening tool for tightening and sealingSave time and effort.
4Having spring-loaded pressure
The coefficient of thermal expansion of polytetrafluoroethylene (PTFE) is very large. When heated and kept at a constant temperature, PTFE will expand, but when cooled during the experiment, it will contract. During the contraction, the PTFE liner cup is more prone to leakage because some leaks are not easy to detect, which affects the accuracy of product analysis. The SR series hydrothermal synthesis kettle of Wuzhou Dingchuang Company is equipped with a high-pressure spring load as standard, which keeps the PTFE inner liner cover at a constant fastening pressure throughout the reaction process, thereby ensuring good sealing of the hydrothermal kettle.
5High voltage resistanceThe design pressure of SR series hydrothermal kettle is 10MPA. Use a pressure of 5MPA. Water in a closed environment of gas-liquid equilibrium will rapidly increase in pressure with the rise of temperature, and its own volume will expand, and the liquid is incompressible. The saturated vapor pressure of water at 250 degrees is 3.8MPA. The coefficient of volume expansion is 25%. In a gas-liquid coexistence system, the liquid volume will increase to 125% of its original value and the pressure will increase to 3.8 MPA.
