Labels such as “purum,” “puriss.,” and “p.a.” are frequently seen on chemical reagent labels and in product catalogs. Purum is commonly translated as “pure” or “pure grade,” but it is not a standardized grade that is uniformly applied across suppliers or associated with a fixed purity ...
在化学试剂标签或产品目录中，经常可以看到“purum”“puriss.”和“p.a.”等标识。Purum通常被译为“纯”或“纯级”，但它并不是一个跨供应商统一执行、对应固定纯度百分数的标准等级。
In tissue engineering research, materials are used not only as reaction raw materials but may also come into direct contact with cells, encapsulate cells, form three-dimensional scaffolds, or participate in the construction of bioinks and injectable hydrogels. Therefore, the evaluation of these ...
在组织工程研究中，材料不仅作为反应原料，还可能直接接触细胞、包埋细胞、形成三维支架，或参与生物墨水和可注射水凝胶的构建。因此，这类产品的评价不能仅看化学纯度，还要考虑残留物、微生物和内毒素控制、材料功能、细胞相容性及批次一致性。 ...
Purity is an important indicator in reagent specifications used to characterize the target component, target element, active component, or specific quality attribute. In actual product labeling, purity does not always equal the mass percentage of a single compound. Its meaning may be jointly ...
纯度是试剂规格中用于表征目标成分、目标元素、有效组分或特定质量属性的重要指标。实际产品标注中的纯度并不总是等同于单一化合物的质量百分含量，其含义可能由检测方法、换算基准、元素计量、异构体组成、同位素丰度、光学纯度及COA检测项目共同限定。 ...
Electronic-grade reagents are mainly used in semiconductors, display panels, photovoltaics, light-emitting diodes, printed circuit boards, electronic components, precision cleaning, and high-end trace analysis. Their main difference from ordinary laboratory reagents is not simply higher assay or ...
电子级试剂主要用于半导体、显示面板、光伏、发光二极管、印制线路板、电子元器件、精密清洗和高端痕量分析等场景。它与普通实验室试剂的主要区别，不只是主含量更高，而是对金属杂质、颗粒、离子残留、有机残留、非挥发残留、包装洁净度和批次稳定性有更严格的控制要求。 ...
The AVI-tag grade is a product quality and technical standard level established around the AviTag and the biotin–streptavidin system. This grade emphasizes achieving highly efficient, quantitative, and site-specific biotinylation of target proteins in advanced applications such as protein ...
