1:一般建议:溶解度为Medlife测试数据,可能与文献描述存在差异。这是由于生产工艺和批次不同产生的正常现象。为了使其更好的溶解,请用37℃加热试管并在超声波水浴中震动片刻。不同批次产品溶解度各有差异,仅做参考,具体以实验方案为准。

2:储存条件:粉末-20°C一般情况可以保存3年,溶于溶剂-80°C一般情况可以保存1年。不同产品及不同批次产品可能存在差异,请细致阅读产品信息,并辅助参考相关文献描述。

The molarity calculator equation
Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)
The dilution calculator equation
Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2
