Overview
In the process of soil nutrient determination, the most common operations of the automatic dilution device are quantitative addition and transfer of solution, which is not only time-consuming but may also bring errors. In order to improve the analysis speed of soil nutrients, specialized dispensers and diluents were used for the quantitative addition and dilution of the solution. Due to the use of multiple types of dispensers and diluents in this method. Now we will introduce its working principle one by one. Note that in the product name, the dispenser and diluter are collectively referred to as dispensers, only with different models.
Product Details
Automatic liquid dilution deviceIn soil nutrient determination, in addition to liquid addition and dilution, two other solutions need to be added for dilution. For example, in soil phosphorus determination, both pure water and color reagents need to be added to the soil extract. To improve efficiency, the equipment is equipped with four liquid addition diluents that integrate liquid addition and dilution, including soil available phosphorus, potassium, calcium, magnesium determination, sulfur determination, ammonium nitrogen determination, and nitrate nitrogen determination. It is actually composed of a set of dispensers and a set of diluents integrated on a pressure rod.
Automatic liquid dilution deviceThe basic working principle is that when the pressure rod is pressed down, different volumes and types of solutions can be drawn from two inlet ports under negative pressure. At the same time, a certain amount of soil extraction solution can be drawn from the inlet and outlet ports. When the pressure rod is moved up, three different solutions can be simultaneously discharged into one container. By adjusting the capacity of different syringes, the functions of adding and diluting can be achieved. Before use, the capacity of each syringe should be carefully adjusted to achieve the requirements of rapid and accurate analysis.
