一般描述

Redi-Dri™ 技术消除了结块和保持盐自由流动所需的复杂操作。让盐保持干燥为您带来准确的结果和更容易处理的盐和缓冲液，从而有助于改善您的结果。与在干燥箱或干燥器中干燥盐或人工破碎盐不同，Redi-Dri™ 确保您的盐在数月之内都易于使用，无需担心抗结剂。即使在重复开启后，您仍然可以确信您的结果始终准确无误。Redi-Dri™让您的盐可以在更长的时间内使用，从而节省您的时间、精力和金钱。

应用

  • 氢氧化钠已被用于细胞染色。
  • 它已被用于人羊膜的脱细胞处理，以便进行细胞培养。
  • 它已被用于免疫染色细胞中荧光团的化学灭活。

特点和优势

  • 提高效率–消除需要松散硬化粉末的时间和精力
  • 安全–避免使用工具大力敲碎团块的风险
  • 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

  1. How does Redi-Dri™ help keep salts and buffers free-flowing?

    Redi-Dri™ products are specially handled and the bottle is specially designed to ensure that the product will remain dry without adding impurities or additives to the product. Ensuring that you receive the highest quality material that is easy to handle.

  2. Are there any special storage conditions that must be maintained?

    No, Redi-Dri™ products can be stored under the same conditions as the equivalent non-Redi-Dri™ products.

  3. How long will material remain free-flowing after it is opened?

    While the exact amount of time your material will remain free-flowing can vary, this largely depends on the ambient storage conditions and how many times it is opened.
