一般描述

氯化钾是一种无机盐，常用于化肥工业。据报道，它是通过对微斜长石进行氯化而得。KCl晶体的本征导电性和非本征导电性已经测定。研究了KCl对线粒体膜、嵴和基质蛋白活性的影响。它有助于在水性介质中制备异恶唑啉。

应用

可用于磷酸盐缓冲液制备，以及蛋白提取和溶解。
氯化钾可用于制备磷酸盐生理缓冲液以及萃取和增溶蛋白质。

氯化钾可用于制备以下物质：
  • 无定形磷酸钙(ACP)沉积溶液，用于Ti试片上的ACP涂层。
  • 改良亚甲蓝(MB)溶液，用于亚甲蓝两相滴定法
  • 含4-(2-羟乙基)-1-哌嗪乙磺酸(HEPES)的人工脑脊液(ACSF)溶液
  • 人造海水

特点和优势

  • 提高效率——免除需要松散硬化粉末的时间和精力
  • 更加安全——避免使用工具大力敲碎团块的风险
  • 更加经济——制备和溶剂化速度更快，提高效率并节约成本
  • 质量保证——经过专业检测的出色品质，无抗结剂添加
  • 灵活的用量选择——有从研究到放大级别的用量规格可供选择
