There are various types of nitrogen blowers, which can be classified into multiple types according to different classification criteria. The following are the main types of nitrogen blowers sorted based on search results:
1. Classified by heating method
Dry bath nitrogen blower: Heating treatment of samples using metal substances as heating carriers. There are three types of heating carriers: aluminum block hole dry bath, aluminum bead bath, and fine yellow sand bath, among which aluminum block hole dry bath and aluminum bead bath are more commonly used. The dry bath nitrogen blower uses an aluminum hot block as the bathroom, which has good heat transfer properties and can rapidly increase the temperature of the sample. Dry heating method has fast heating and cooling, and the heating temperature can reach up to about 180 ℃. It is a rapid heating method.
Water bath nitrogen blower: Heating usually involves placing the test tube to be heated in a beaker filled with water, heating the water with a heat source, and then transferring the heat to the test tube, which is an indirect heating process. During the heating process of the water bath, a thermometer can be inserted into the water in the beaker to observe the water temperature in real time, which can effectively control the temperature of the water. The water bath nitrogen blower heats up slowly and cools down slowly, and the heating temperature does not exceed 100 ℃, making it a gentle heating method.
2. Classify according to other characteristics
Fully automatic water bath nitrogen blowing concentrator: This is a highly automated nitrogen blowing device that can automatically concentrate samples, improve experimental efficiency and accuracy.
Circular and square nitrogen blowers: This is a classification based on the external structure of the nitrogen blower. Circular and square nitrogen blowers may have different sample processing quantities and layouts, and are suitable for different experimental needs.
The above are the main types of nitrogen blowers, which are suitable for different experimental scenarios and sample processing needs. When choosing a nitrogen blower, it is necessary to determine the appropriate type based on specific experimental requirements and sample characteristics.
