产品介绍

除了ISO9001:2008认证,Aladdin的pH值分析也通过了ISO 17025-“检测和校准实验室功能的通用要求”这一认证。Aladdin的ISO17025认证在以下三个关键领域获得独立证明: 1.pH分析具有技术有效性,并由高素质员工完全掌握执行过程 2.我们对pH值分析准确性的声明是有效的,我们已经对测量计算的不确定性方面的精度进行了正确量化 3.我们的pH值分析可溯源至NIST的SRM。值得注意的是,NIST对SRM的可溯源性并不实行监督。任何pH校正液生产商都可以声称自己的校正液可追踪至NIST,但只有经过ISO17025认证的生产商才具备可追踪性的独立声明。 ●稳定性 Aladdin 的pH校正液的特殊配制确保了其稳定性。我们使用的包装也经过挑选和测试,以提供最大的稳定性。而且,我们已经对刚刚打开和装有半瓶pH校正液进行了稳定性试验,以验证其保质期。大多数Aladdin的pH校正液有效期都是自生产日期起的两年或三年内。 这意味着pH校正液的有效期为绝对值并且有较长的“有效寿命”。我们不会在开瓶后标出使用期短,也没有必要随手记录“打开日期”和“保存期”。如果是Aladdin的pH校正液,您只需打开瓶子即可开始使用。 ●包装选择 除了常规瓶体,Aladdin还提供多种便捷的pH校正液包装选择: 1.双颈瓶。这种瓶子是使用便携式pH计的理想选择。其密闭的校准空间能防止污染,消除携带单独的测量容器或校正液倒在其他地方的必要。 2.盒中袋式容器。此包装含有一个可折叠的塑料衬垫纸板箱。这样就节省了空间,减少了大量包装废弃物的处理。每个盒中袋式容器都配有水龙头,可以很容易进行使用。 3.胶囊。这是个创新概念 4.Recal校正液。Recal是装在一次性广口容器中的一个pH校准液系列。这种校正液可直接用于电极校准,并在用完后进行丢弃。 ●广泛的pH值区间 所有产品都有较长的保质期并进行符合规范的生产,范围从pH值1.00到pH值13.00(含)。所有产品都有齐全的分析证书,其中对证书N.I.S.T的追踪性进行了概述。标签上印有温度依赖性数据,还有批号和有效期。 ●校准液 Aladdin的pH校正液用于大多数主要制造商的仪器 ●对照品 Aladdin的pH校正液设定的广泛的产品区间意味着Aladdin将有一中通用的pH对照品。

In addition to the certification to ISO9001:2008,Aladdin’s pH analysis is also accredited to ISO 17025 - “General requirements for the competence of testing and calibration laboratories”. Aladdin’s accreditation to ISO17025 gives independent proof of three key areas: 1. Our pH analysis is technically valid and is carried out in a thoroughly controlled manner by highly - qualified staff. 2. Our claims over the accuracy of our pH analysis are valid and we have properly quantified our accuracy in our Uncertainty of Measurement calculations. 3. Our pH analysis is traceable to NIST SRMs. It is important to note that NIST do not police claims of traceability to their SRMs. Any manufacturer of pH buffers can claim that their buffers are traceable to NIST, but only manufacturers that are accredited to ISO17025 have independent proof of their traceability.
●Stability Aladdin’s pH buffers have been specially formulated to ensure their stability. The packaging bottles that we use have also been selected and tested to provide maximum stability. We have conducted stability trials on both freshly-opened and part-full bottles of our pH buffers to validate their shelf-life. Most of Aladdin’s pH buffers have an expiry date of either 2 years or 3 years from the date of manufacture.
● Packaging Options Besides regular bottles,Aladdin offer pH buffers in a wide variety of convenient packaging options: 1. Twin-neck bottles. These bottles are ideal for use with portable pH meters. Their integral calibration chamber prevents contamination and removes the need to carry a separate measuring container or to decant buffers for use in the field. 2. Bag-in-Box containers. This packaging consists of a cardboard box with a collapsible plastic liner. This offers a space-saving alternative to bottles and reduces the amount of packaging waste for disposal. Every Bag-in-Box container is supplied with a tap to allow the contents to be easily dispensed. 3. Capsules. The presentation of pH buff
