Digital constant temperature digestion instrument

1Digital constant temperature digestion instrumentprinciple
Place the sample and digestive solution in the digestive tract and perform gradient temperature controlled heating on a digital programmable constant temperature digestion instrument to thoroughly digest the sample for various instrument and chemical analyses.

IIDigital constant temperature digestion instrumentDigestive sample range
Food samples, environmental samples, biological samples (blood, urine, hair), cosmetics, etc.

IIIApplicable analysis scope
Sample pretreatment using flame atomic absorption spectrometer, flameless atomic absorption spectrometer, atomic fluorescence spectrometer, ICP-AES, ICP-MS polarograph, chemical analysis and other methods.

4： Performance of OBD-25 digital programmable constant temperature digestion instrument
(1) Temperature range:
Room temperature to 300 ℃ (special note: temperature refers to the temperature of the constant temperature block, the temperature of the digestion sample solution, and the boiling point of the digestion solution *).
(2) Stability:+2 ℃.
(3) Digestive orifice number: 18, aperture: 26mm, suitable for digestive tubes with an outer diameter of 25mm.
(4) Power: 1500W
(5) Temperature control method: Use a dial code to set the digestion temperature. (Please refer to the temperature controller manual for temperature setting)

5： OBD-25 digital programmable constant temperature digestion instrument reagents and equipment:
(1) Digestive fluid: nitric acid+high acidity (4+1)
(2) Plastic tweezers or bamboo clips: used to extract materials from 10% nitric acid solution soaked in glass equipment
(3) Digestive tube: 25mm outer diameter x 80mm long flat low hard glass, soaked in 10% nitric acid before digestion, washed and dried before use
