人工海水又称人造海水,英文名称为 Artificial Sea Water,用于替代天然海水,方便实验室条件下培养真菌等试验的需求。
含重金属人工海水粉剂 (ASW-HM, ASTM) 是严格参照 ASTM D1141-98 标准配制的合成海盐混合物。通过精确模拟天然海水的离子组成,消除了天然海水来源的变异性,为各类实验提供了高度可重复的标准环境。产品为干粉状,具有保存方便、配制简单、批次稳定性好的特点。其用途如下:
①微生物学:海洋真菌、放线菌及其他嗜盐微生物的分离、培养与保藏。
②海洋生物学:海洋藻类、无脊椎动物(如海胆、海星、水母)卵或幼体的培养,以及小型海洋生物的暂养。
③分析化学:作为标准基质,用于海水成分分析方法的校正、校准(如盐度、电导率、特定离子电极),以及海洋腐蚀相关试验。
本产品主要由氯化钠、氯化镁、硫酸钠、氯化钙、氯化钾、硼酸、氟化钠、氯化锶等组成,总盐度为36‰,pH约为8.2,并含有钡盐、铅盐、铜盐等重金属物质。该试剂仅用于科研领域,不适用于临床诊断或其他用途。

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 with Heavy Metals (ASW-HM, ASTM) is a synthetic sea salt mixture formulated in strict accordance with ASTM D1141-98. By accurately simulating the ionic composition of natural seawater, it eliminates variations associated with natural seawater sources and provides a highly reproducible, standardized environment for various experiments. The product is supplied as a dry powder, offering convenient storage, easy preparation, and excellent batch-to-batch consistency. Its applications include:
① Microbiology: Isolation, cultivation, and preservation of marine fungi, actinomycetes, and other halophilic microorganisms.
② Marine Biology: Cultivation of marine algae, eggs or larvae of marine invertebrates (such as sea urchins, starfish, and jellyfish), and temporary maintenance of small marine organisms.
③ Analytical Chemistry: Used as a standard matrix for the calibration and standardization of seawater composition analysis methods (such as salinity, conductivity, and ion-selective electrode measurements), as well as for marine corrosion testing.
This product primarily consists of sodium chloride, magnesium chloride, sodium sulfate, calcium chloride, potassium chloride, boric acid, sodium fluoride, strontium chloride, and other components. It has a total salinity of 36‰ and an approximate pH of 8.2, and also contains heavy metal compounds such as barium, lead, and copper salts. This reagent is intended for research use only and is not suitable for clinical diagnosis or other purposes.

Operating Procedures (For Reference Only, 1L Specification):
1、Dissolve Reagent 1 in 900ml of deionized water. After it has completely dissolved, add Reagent 2 and mix thoroughly until completely dissolved, then add Reagent 3. Make up the volume to 1 liter and adjust the pH to 8.2 with dilute hydrochloric acid or sodium hydroxide; filter before use if necessary.
2、If sterilization is required, autoclave at 121°C for 15 minutes (Note: Prolonged exposure to high temperatures may cause slight precipitation, which generally does not affect use).
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.
