Graphite Digestion System

1、 Product Introduction:

The principle of graphite digestion instrument digestion: Place the sample and digestion solution in a digestion tube and digest them at a constant temperature, so that the sample can be used for various instrument analysis and chemical analysis after digestion. Scope of digestion samples: food samples, various water samples, biological samples (blood, urine, hair), cosmetics, etc.

2、 6 major features of graphite digestion analyzer:
1. The surrounding heat transfer method has fast digestion speed, high efficiency, and energy saving.
2goodThe cooling system ensures that the shell temperature is below 38 ℃, resulting in a longer service life and greater safety.
3. Thermal insulation performance *, can maintain insulation for up to 5 hours after power failure.
4. The heating rate is fast, reaching 150 ℃ in 15 minutes with uniform temperature.
5. Adopting a new temperature control program and heating method, the temperature difference between holes is truly reduced to less than ± 0.5 ℃.
6. The foolproof operating program is easier to learn and safer to use.

7. The 30 segment virtual temperature rise function can achieve the display of the set temperature curve and the actual temperature curve graph; The heating speed can be adjusted, and the heating time and holding time can be edited.

Processing methods for electronic products: SJ/T 11365-2006, etc

3、 Technical parameters:

1. Number of dissolution pores: 12, 20; 36, 40, 60, 80, 100

(Our factory can produce special specifications according to customer requirements)

2. Dissolution pore size: diameter ≥ 30mm, depth ≥ 50mm;

3. Panel size: length x width ≥ 415 mm x 200 mm (20 hole example);

4. External dimensions: length x width x height ≥ 500 mm x 260 mm x 250 mm (20 hole example);

5. Weight: ≤ 30kg;

6. Temperature control range: room temperature~500 ℃;

7. Temperature control accuracy: ± 0.1 ℃;

8. Power supply: AC 220V/50Hz;

9. Adopting isostatic pressing high-purity ultrafine graphite heating module for heating, the digestion consistency and repeatability are good, the temperature difference between holes is ≤± 1.5 ℃, and the high-performance intelligent PID controller has multi-stage temperature rise and fall programming, fast heating speed, and high temperature control accuracy;

10. Digital intelligent program temperature control, realizing 30 stage program heating and controlling heating holding time, automatically stopping heating after completing the heating program. It can prevent foam overflow of easily boiling samples due to high temperature, and also avoid unnecessary loss of acid due to high temperature boiling point of acid solution, which not only shortens digestion time, but also saves acid and reduces environmental pollution;

11. The upper and lower split design separates the controller from the digestion unit to protect electronic components from corrosion; The double-layer insulation design between the heating part and the control part effectively protects the control part from high temperature damage, thereby extending the service life of the instrument. The workbench is coated with Teflon for anti-corrosion treatment, and the whole machine is treated with anti-corrosion coating to ensure the normal operation of the instrument in acidic environments.

12. The digestion instrument has a high and low temperature alarm function;

13. Configuration List:(Optional configuration)

(1) One graphite electric digestion host,

(2) One 20 hole stainless steel digestion tube bracket,

(3) A set of 20 borosilicate glass digestion tubes,

(4) A set of 20 polytetrafluoroethylene digestion tubes.

Our factory can produce other hole numbers and parameter requirements.
