操作步骤(仅供参考,1L规格):
1、将试剂一溶解于900ml去离子水中,用稀盐酸或氢氧化钠调整pH值为7.3~7.5,待完全溶解后,再加入试剂二,充分混合溶解,定容至1升,调整最终pH值为7.4~7.6即可;如有必要,可过滤后使用。
注意事项:
1、试剂一含镁盐、硫酸盐、碳酸盐,溶于水后呈弱碱性,若有浑浊状沉淀,可先用稀盐酸调节pH值至澄清(7.3~7.5)才可进行后续操作。
2、试剂二含钙盐,为白色粉末或球状颗粒,有吸水性,应避免存放于湿度较高的地方。
3、为了您的安全和健康,请穿实验服并戴一次性手套操作。
Artificial seawater (ASW), also known as synthetic seawater, is used as a substitute for natural seawater to facilitate laboratory experiments, such as fungal cultivation.
Artificial Seawater Powder (ASW, Millero F J) is formulated based on the Millero F J formulation. It primarily consists of sodium chloride, magnesium chloride, sodium sulfate, calcium chloride, potassium chloride, boric acid, sodium fluoride, strontium chloride, and other components, with a salinity of 35.17‰. This reagent is intended for research use only and is not suitable for clinical diagnosis or other purposes.
Contents & Storage

Preparation Procedure (For Reference Only, 1 L Specification):
1. Dissolve Reagent 1 in 900 mL of deionized water and adjust the pH to 7.3–7.5 using dilute hydrochloric acid or sodium hydroxide. Once completely dissolved, add Reagent 2 and mix thoroughly until fully dissolved. Adjust the final volume to 1 L, then adjust the final pH to 7.4–7.6. Filter before use if necessary.
Precautions:
1. Reagent 1 contains magnesium salts, sulfates, and carbonates, and produces a slightly alkaline solution when dissolved in water. If turbidity or precipitation occurs, adjust the pH to 7.3–7.5 using dilute hydrochloric acid until the solution becomes clear before proceeding with subsequent steps.
2. Reagent 2 contains calcium salts and is supplied as a white powder or spherical granules. It is hygroscopic and should not be stored in environments with high humidity.
3. For your safety and health, wear a laboratory coat and disposable gloves when handling this product.
