一般描述

Redi-Dri™ 技术消除了结块，也不需要复杂的程序来保持盐的自由流动。保持盐干燥有助于改进结果，提供准确的测量和更容易处理的盐和缓冲液。Redi-Dri™ 不需要在烤箱或干燥器中干燥盐，也不需要手动将盐分开，可以确保盐在几个月内保持易于使用，而无需担心防结块剂。即使在反复打开后，你也可以确信你的结果总是准确的。Redi-Dri™ 可以节省你的时间、精力和金钱，让你的盐可以使用更长时间！

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。

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

  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.

Metabolic-associated fatty liver disease (MAFLD) represents a spectrum of disease states ranging from simple steatosis to non-alcoholic steatohepatitis (NASH). Hepatic macrophages, specifically Kupffer cells (KCs), are suggested to play important roles in the pathogenesis of MAFLD through their activation, although

Redi-Dri™ – The World of Free-flowing Hygroscopic Products

Redi-Dri™ prevents hygroscopic powders, such as inorganic salts, from absorbing moisture and forming clumps, leaving the salts free-flowing every time.

Analysis of Bisphenol A in Food by Solid Phase Microextraction Using an Overcoated Fiber

Bisphenol A (BPA) is suspected to be an endocrine disruptor. Regulations on specific migration limits (SML) from food contact materials are getting tighter (EU 2018/213) requiring more sensitive determinations. An overcoated SPME fiber provides the durability necessary for direct immersion into foods such as canned soup and pumpkin, allowing for low level analysis of BPA via SPME-GC-MS/MS.
