Uncolored Buffer Solutions

Bernd Kraft offers a selection of high-quality, uncolored pH buffers for your specific applications. All buffer solutions are stabilized and available in convenient bottles and different container sizes. From pH 1 and pH 4 buffer solutions to pH 7 and pH 13 solutions, we cover the entire range of pH buffers.

Based on ISO 9001 and our more than 40 years of experience, we prepare our pH buffers exclusively in Germany and in compliance with the highest quality and environmental standards. All buffer solutions are traceable to NIST (National Institute of Standards and Technology) and thus safe to use. The stated pH values correspond to a temperature of 20°C.

Convenient buffer boxes for your calibration tasks
Our XS buffer boxes are the ideal solution for a variety of calibration issues in the lab and in processes. A box contains 30 small containers each with 25 ml of readily prepared buffer solution. They are homogeneously sorted, either coloured or uncoloured or as an assortment of frequently required pH values between pH 1.00 and pH 11.00.

Each 25 ml container carries a seal of authenticity, allowing you to immediately identify whether it has been opened or not. If unopened, contamination by carbon dioxide, microorganisms or other substances can be ruled out.
