HM-HL8 reflux digestion device Introduction
The reflux digestion device is a classical method for analyzing a COD international digestion device for controlling a heating electric furnace when using a microcomputer technology.
In the national standard HJ 828-2017 analytical method, the conditions of reflux heating digestion time, solution acidity, oxidant dosage and other conditions are strictly defined. The standard reflux resolver fully complies with the basic principles of international standards (ISO) and national standards (HJ), ensuring a 2 hour reflux digestion operation and ensuring the accuracy of the analysis results.
Aqueous, HNO3 or HCl reflux (water) digestion for heavy metal analysis in soil, e-waste, water, food, feed, textiles or meat hydroxyproline
Technical Parameters
Measuring range: 10-700mg/L (measured after dilution of water sample greater than 700mg/L)
Digestion time: 10 minutes - 2 hours and 30 minutes (can be set according to your needs)
Accuracy control: relative deviation of 8 parallel samples <±10%
Number of digestion samples: 8 (using 24# grinding mouth 250ml conical flask)
Heating power: ≤1600W, adjustable
Cooling method: 4 fan cooling cone spur reflux condenser, 2 fan ceramic panel cooling
Display mode: true color LCD screen, Chinese display
Instrument size (length * width * height): 440 * 300 * 620mm
Safety protection: over-temperature automatic protection, heating panel cooling to 50 degrees fan stop
Digestion control: Microcomputer intelligent control, which can simultaneously heat and recirculate 8 250ML grinding cones.
Digestion timing: Display the countdown time of the digestion time. After the digestion is completed, the instrument automatically stops heating, and the instrument fan system continues to work, ensuring good heat dissipation of the machine, which can be left unattended.
Condensation mode: The improved glass cone-recessed reflux condenser is used instead of the spherical condenser tube, and the circulating water cooling is replaced by air-cooling and static water-cooling technology, which is convenient to operate.
Cooling effect: The cooling part is mainly completed by the cone water condensing condenser static water cooling and fan air cooling. The upper part of the condensing pipe is a spherical 3 bubble and surrounds the stationary cooling water pipe, and the lower part is a "tapered" tube. The 10 sets of cone thorns increase the cooling area and block the passage of volatile substances and vapors. Good sample reflow cooling effect.
