Overview

The 40 hole graphite digestion furnace KRX-40S adopts a one-time digestion of 40 samples, meeting the needs of a large amount of digestion work and solving the problem of unit digestion due to long digestion time. It can be combined with a 40 position automatic sampling system to complete the digestion in one go. This product uses high-purity graphite as the heating module, which has the advantages of high temperature resistance, corrosion resistance, and uniform heat transfer.

Product Details

40孔石墨消煮炉

40 hole graphite digestion furnaceIt is a sample digestion and transformation equipment developed based on the classical wet digestion principle. It is mainly used in agriculture, forestry, environmental protection, geology and petroleum, chemical industry, food and other departments, as well as in higher education institutions and scientific research departments for the digestion treatment of samples such as plants, seeds, feed, soil, and ores before chemical analysis. It is the best supporting product for Kjeldahl nitrogen analyzer.

Product Features

1. The heating element is made of high-purity graphite material that has undergone surface hard oxidation treatment, which has the advantages of fast heating speed, long service life, and high cost-effectiveness. The design temperature is 550 ℃.

2. The temperature control system adopts a 5.6-inch color touch screen, with Chinese English conversion and simple operation.

3. The formula program input adopts a table format fast input method, which has clear logic, fast speed, and is not easy to make mistakes.

4.0-40 programs can be freely selected and set.

5. Choose between single point heating and curve heating modes.

6. Intelligent P, I, D self-tuning temperature control has high precision, reliability, and stability.

7. Solid state relays are selected for the electrical control system, which have strong noise reduction and anti-interference capabilities.

8. Segmented power supply and anti power outage restart function can avoid potential risks. Equipped with over temperature, over voltage, and over-current protection modules.
