HTF Flanged Hydrothermal Reactor
Using metal hard seal, the fastening bolts are tightened symmetrically to form a sealed vessel, thus creating a high-temperature-resistant hydrothermal reaction sealing environment.
Design volume: 10/25/50/100 mL
Maximum operating pressure: 49 bar
Maximum operating temperature: 500 ℃
Sealing form: metal hard seal
Material of liner: None
Hydrothermal Reactor: a high-pressure digestion tank, also known as a sample dissolver, a pressure dissolver, a hydrothermal reactor, a digestion tank, a PTFE high-pressure tank, utilizes the strong acid or strong alkali in the tank and the high-temperature and high-pressure sealing environment to rapidly dissolve the insoluble substances. It is a helpful method to carry out sample digestion in the determination of micro elements and trace elements. It is mainly used for the digestion of heavy metals, agricultural residues, foods, sludge, rare earth, aquatic products and organic matters in the sample pretreatment stage.
The Company provides digestion tanks with the volume of 10 mL, 25 mL, 50 mL, 100 mL, 200 mL, 300 mL, 500 mL and 1,000 mL. The tanks have a safe temperature of 260 ℃ and bear the highest pressure of 3 MPa. With the dual protection of high-quality non-magnetic 0Cr18Ni9Ti stainless steel outer structure and PTFE liner, it can bear the acid and alkali liquid. With its beautiful appearance, reasonable structure, simple operation procedures and good corrosion resistance, it is an ideal product for sample digestion in the university laboratory, environmental monitoring, sanitation and epidemic prevention and quality supervision. With a operating pressure of no more than 3 MPa, various heating temperatures and heating times can be set according to the technical indexes of different samples. In addition, various specifications of high-pressure digestion tank liner (PTFE) can be customized (a drawing or sample should be provided).
Precautions in Use of Hydrothermal Reactor
1. Before using the hydrothermal reactor, please carefully check the saturated vapor pressure of the solvent at the reaction temperature, and confirm that the maximum allowable operating pressure of the hydrothermal reactor will not be exceeded
2. For the HTG/HTS series hydrothermal reactor, as the liner is made of PTFE, which is compressible under the high-temperature and high-pressure, the reactor lid and set screw should not be overtightened, so as to avoid severe deformation of the liner caused by thermal expansion under high temperature and high pressure
3. In case the operating temperature of the hydrothermal reactor exceeds 150 ℃, it is recommended to apply a layer of high-temperature lithium base grease on the thread before tightening the reactor lid to prevent the stainless steel thread from galling (if silver-plated reactor lid is used, no grease is required
4. It is prohibited to use the hydrothermal reactor under the following circumstances:
a. The solvent has a boiling point lower than 60 ℃ (e.g., ether, acetone, and dichloromethane)
b. A large amount of gas will be generated in the reaction
c. Materials with flammable, explosive or highly or extremely toxic properties (see Classification of Toxic Hazard and Explosive Risk of Chemical Mediums in Pressure Vessels (HG20660-2000))
