Alfa Aesar is proud to offer all the necessary tools an analytical chemist will need for quick and easy determinations of the pH of many materials. We offer the following:

Specpure® pH buffer solutions

Specpure® pH buffer solutions are accompanied by a NIST-traceable Certificate of Analysis and individual expiration date stickers. These solutions are guaranteed for one year from date of shipment.

ColorpHast® pH Strips

ColorpHast® pH Strips are offered as individual units or in a package of 6. We offer strips that cover the entire pH range, as well as those that cover more narrow ranges on the pH scale. Each unit contains 100 strips.

pH Meters

We offer a waterproof pH tester. The waterproof housings of the pH waterproof testers provide complete protection in outdoor applications and harsh industrial environments, as well as accidental spills. We also offer the Checker pH Meter. The Checker pH Meter is a lightweight, pocket-sized pH tester.
