糖度/折射率标准品Reagecon 公司成立于1986年 ,技术服务已超过25年的经验,提供完整的支持解决方案的实验室。作为一个技术卓越中心,是第一个在爱尔兰获得INAB(ISO17025) 校准认证和在体积、重量和温度首次提供INAB认证的公司。Reagecon公司可以生产2,000多种受到认可的、有证书可以溯源的标准品、试剂和化学溶液,他们的产品质量符合ISO17025、USP、EP和JP,客户遍布全球80多个国家。 Reagecon 制造了几套糖度/折射率标准液以便轻松校准所有类型的折射计。所有这些产品的制造均采用高纯度原材料。第一系列产品编号BS00至 BS60,是按照ICUMSA指南制造且延长了12周的保质期。随后系列的产品-编号BS00S 至BS60S(单瓶)和BS00S6至 BS60S6(六瓶装),与ICUMSA系列的原材料相同:但保质期延长了一年。这些产品对于不需按照 ICUMSA 指南的用户来说价值斐然。其余的产品-编号RIBS00S 至 RIBS60S,与已描述的稳定的糖度标准液的组成部分以及保质期(1 年)等同但以等效折射率(R.I) 值表示其验证值。所有这些产品是基于重量/重量的基本原理进行重量分析从而制备而成的。溶质(蔗糖)和溶剂(水)都于 Reagecon 技术人员利用OIML 可追溯重量进行校准的衡器上进行称重。Reagecon持有校准非自动称量仪器的 ISO17025 认证(INAB 参考:265C)。由此产生的校准重量证书按照 ISO/IEC17025 的要求发出。标准液的折射率利用高性能分度温控折射计来进行验证。该仪器的校准工作利用 ISOGuide 34 认证的、糖度值类似于下列产品的高纯度糖度标准液来完成。 有效期产品分类货号描述中文名称包装糖度标准液– ICUMSA – 12周保质期12wksR20BS00Sucrose (Brix) Standard 0% -
