Technical pH Buffer solutions@25℃（pH 9.21±0.02）

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.
