NJ high pressure digestion tank 100ml hydrothermal synthesis reactor can customize the pressure tank

  Overview: , The sealed high-pressure digestion tank is a stainless steel container with Teflon lining inside
The stainless steel container has precision threads to compress the Teflon lining to achieve sealing effect
Polytetrafluoroethylene liner can be filled with corrosive substances such as strong acid or alkali, and the sample can be heated and dissolved under closed conditions
According to the situation of reactants, the lining can also be made of imported polytetrafluoroethylene

Product introduction:
Sealed high-pressure digestion tank, also known as sealed high-pressure digestion tank, pressure digester, pressure digestion tank, digestion tank and polytetrafluoroethylene high-pressure tank, is a closed container that can decompose insoluble substances for sample pretreatment in chemical analysis methods such as gas phase, liquid phase, plasma spectrum mass spectrometry, atomic absorption and atomic fluorescence

Application fields:
It is mainly used in food, medicine, CDC, dairy products, environmental center, agricultural products, seafood, aquatic products and other industries to detect heavy metals such as lead, chromium, cadmium, methylmercury and inorganic arsenic in tea, fruits and vegetables, grain and oil, eggs, meat, milk powder and so on

Technical parameters:

specification and model	nj-zh-5, 10, 15, 20, 25, 30, 50, 60, 100, 200, 250, 500, 1000ml, etc
composition method	one set includes: an outer tank and an inner cup
outer tank material	non magnetic stainless steel
inner cup material and temperature resistance	1 The temperature resistance of domestic PTFE is within 200 ℃ 2 TFM can withstand 230-260 ℃, has good pressure resistance, good recovery, low metal element value, lead and uranium content less than 0 01ppb, and has no dissolution and precipitation (involving reagents with large gas production of hydrogen peroxide or perchloric acid, TFM material is recommended)
usage conditions	the whole set is put into the oven and can withstand 5MPa (50kg)
precautions	1 The amount of solvent for digestion depends on different experiments, generally 1 / 3 to 1 / 5 of the capacity of the inner cup 2 If perchloric acid and hydrogen peroxide are used in the experiment, the dosage should not be too much, and cold nitrification should be carried out overnight 3 Just after digestion, because the pressure inside is too high, it is easy to open when it is cooled to room temperature 4 The inner and outer tanks of the same specification are common, and the domestic or TFM tanks of the same specification are also common
supporting products	the inner cup can be equipped with an acid catcher for acid driving and digestion experiments in the later stage
