Note: (1) Please purchase from this reagent tank for the lack of concentrated sulfuric acid (mainly used when testing soil organic matter).
(2) After the chemical liquid in the reagent box is used, it can be purchased at the local chemical store. If individual reagents are not available for a time, you can contact the Qiangsheng Instrument Center for purchasing.

Note: The use and maintenance of some vessels: 1. Wash the new glassware first with water, then soak it in hot potassium dichromate bath to remove impure substances, then rinse with water, and finally wash it several times with distilled water. . 2. For greased glassware, it can be washed with hot soapy water or alkaline alcohol lotion, and finally washed several times with distilled water. 3. Wash the plastic utensils with 1+3 nitric acid and rinse with distilled water. 4. When using vessels such as pipettes, volumetric flasks, and graduated cylinders in the experiment, make the liquid bottom surface parallel to the scale of the vessel. 5. When using the balance, place the balance on the workbench steadily, so that the pointer on both sides of the balance is stable on the central tick line. If the pointer is continuously swinging to both sides, the balance can be adjusted so that the swing distance of both sides of the pointer is equal. 6, special attention, in the experiment using concentrated sulfuric acid and water, concentrated sulfuric acid should be slowly injected into the water, can not be injected into the concentrated sulfuric acid water.
