本品为即用型饱和氯化钠水溶液,由氯化钠(Sodium Chloride,CAS:7647-14-5,分子量 58.44)溶于去离子水配制而成,25℃时溶解度约为 36 g / 100 g 水。可用于核酸盐析沉淀、蛋白样品前处理、渗透压调节、胶体化学实验及高离子强度反应体系配制。
本品为饱和水溶液,温度降低时瓶底易析出白色氯化钠结晶,属于该体系固有物理现象,并非试剂变质。使用前置于室温水浴复溶并充分摇匀,即可正常使用,不影响性能。水分挥发会加剧盐结晶析出,使用后请及时旋紧瓶盖。禁止冷冻保存,冷冻会造成大量结晶析出。
操作步骤(仅供参考):
根据实验具体要求操作。
注意事项:
1、为了您的安全和健康,请穿实验服并戴一次性手套操作。
2、本产品仅用于科研,严禁他用。
This product is a ready-to-use saturated aqueous solution of sodium chloride, prepared by dissolving sodium chloride (NaCl, CAS: 7647-14-5, molecular weight: 58.44) in deionized water. Solubility at 25 °C is approximately 36 g per 100 g water. It is suitable for nucleic acid salting-out precipitation, protein sample preparation, osmotic pressure adjustment, colloid chemistry experiments, and preparation of high ionic strength reaction systems.
This product is a saturated aqueous solution. When the temperature decreases, white sodium chloride crystals may precipitate at the bottom of the container — this is an inherent physical characteristic of the system and does not indicate product deterioration. Before use, warm to room temperature and mix thoroughly to redissolve the crystals; the solution can then be used normally without any loss of performance. Evaporation of water will exacerbate crystallization; please tighten the cap promptly after use. Do not freeze, as freezing will cause extensive crystallization.
Procedure (for reference only):
Operate according to the specific requirements of the experiment.
Precautions:
1.For your safety and health, please wear a lab coat and disposable gloves during operation.
2.This product is for research use only. Strictly prohibited for any other use.
