Teflon series utensils have been used in the laboratory for long-term storage of standard solutions, standard samples, organic solvents, strongly corrosive samples, and scientific research samples because of their very low blank value of metal elements and superior chemical properties.
High pressure digestion tank, it can decompose of refractory material is a kind of airtight container, in the gas phase, liquid phase, plasma mass spectrometry, atomic absorption and atomic fluorescence spectrum in the chemical analysis methods such as sample preparation, used in food, medicine, the centers for disease control and prevention, more dairy products, environmental center, agricultural products, seafood, aquatic products and other industries to green tea art, rare earths, fruits and vegetables, grain and oil, eggs, meat, milk powder, etc in the lead, cadmium, chromium, methyl mercury, inorganic arsenic and other heavy metal detection.
Our unit digestion tank solved the customer in the process of digestion in a large number, high requirements, small volume and difficult to resolve the problem.
| Item name | digestion tank |
| Size | 5-1000ML |
| Component | The outside SS tank and inside PTFE/TFM vessel |
| Outside material | non-magnetic stainless steel |
| Inside material and highlights | 1.PTFE(can underbear within 200ºC) |
| 2.TFM(cam underbear within 230-260ºC),better pressure resistance,low blank value of metal elements,lead/uranium content less than 0.01ppb, no dissolution and precipitation | |
| Usage | Put the whole system in the oven,underbear 5Mpa(50kgs) |
| Notes | Amount of solvent for digestion depends on different experiment,normal occupy 1/3-1/5 of the inner cup |
| If perchloric acid and hydrogen peroxide are used in the experiment, the dosage should not be too much. Cold nitrification should be carried out overnight . | |
| The pressure inside is too high after digestion, it is easy to open when cooled to room temperature | |
| Matching products | The inner cup can be used for catch a acid and digestion experiments in the later stage |
