一般描述

氯化钠固体熔点可达801 °C。
Redi-Dri technology eliminates clumping and the need for complicated procedures to keep your salts free-flowing. Keeping your salts dry helps improve your results by giving accurate measurements and easier-to-handle salts and buffers. Rather than drying your salts in an oven or desiccator or breaking them apart manually, Redi-Dri ensures that your salts will remain easy-to-use for months without worrying about anti-caking agents. Even after repeated openings you can be assured that your results are always accurate. Redi-Dri saves you time, energy and money by keeping your salts usable for longer.

应用

该氯化钠已用于制备tris缓冲液、磷酸缓冲盐、MPM-2(有丝分裂蛋白单克隆2)细胞裂解缓冲液、免疫沉淀洗涤缓冲液、LB (Luria-Bertani)培养基和透析缓冲液。
