How to choose a digestive furnace?

The digestion furnace plays an important role in protein detection. How to choose a suitable digestion furnace?

The indicators of the digestion furnace should pay attention to the following points:

*Effective temperature control is necessary. To enable sample nitrification, temperature is required. If there is a temperature control program for the digestion furnace, it can effectively meet the needs of the sample.

*Good insulation measures are required. If the insulation material is weak, it will inevitably cause temperature instability. A thicker insulation layer for the instrument is necessary for temperature stability. Therefore, the thickness and material of insulation materials are important indicators

*The selection of heating element and heat carrier can be based on the user's needs to choose different heat carriers. Next, we will discuss the selection of heating elements and heat carriers. There are mainly two good ways to heat up now

#Infrared heating relies on thermal radiation to heat the sample. The characteristics are: fast heating, small thermal inertia, and accurate temperature control. Generally used for nitration of samples with high requirements. For example, there are high and fast heating and cooling requirements. Programmed heating allows users to choose a heating curve based on the characteristics of their sample, or to select segmented heating, which is more conducive to the digestion of the sample. Thereby eliminating the phenomenon of sample wall hanging and greatly improving the nitrification efficiency of the sample

#Aluminum ingot heating relies on the aluminum ingot to transfer heat to the sample. Characteristics: Slow heating, large thermal inertia, stable temperature, and good temperature consistency between each sample well due to the good thermal conductivity of aluminum ingots. Widely used as a heat carrier in digestion furnaces, but it should also be noted that even a thin aluminum ingot cannot maintain a constant temperature. Therefore, when choosing an aluminum ingot digestion furnace, the thickness of the aluminum ingot is also an evaluation indicator.

#Graphite heating relies on the conduction of graphite to the sample volume. Characteristics: Large thermal inertia, slow heating, poor thermal conductivity of graphite (compared to aluminum ingots), resulting in uneven temperature between sample pores, which can easily lead to prolonged nitration time between samples. However, due to the low cost of graphite, graphite digestion furnaces are cheap and have a certain appeal to some low-end users.

In addition, attention should be paid to the protection functions of the digestion furnace: temperature stability and uniform protection, overcurrent, leakage, and short circuit protection.
