Bis-Tris buffer (2,2-Bis(hydroxymethyl)-2,2',2''-nitrilotriethanol) is a zwitterionic biological buffer with an effective buffering range of approximately pH 5.8-7.2, making it well suited for applications near physiological pH. Compared to Tris buffer, Bis-Tris exhibits reduced temperature- and concentration-dependent pH shifts and minimal interaction with divalent metal ions.

Bis-Tris buffer solutions are commonly used in Bis-Tris gel electrophoresis systems, protein separation workflows, enzyme activity assays, and general biochemical applications where consistent pH control is essential. We offer ready-to-use Bis-Tris buffer solutions to eliminate in-house preparation and reduce variability in sensitive workflows.

Our Bis-Tris buffer solutions are supplied as ready-to-use formulations, saving time and minimizing the variability associated with manual buffer preparation. Each Bis-Tris buffer solution is manufactured to precise specifications to ensure reliable buffering performance across applications.

Our Bis-Tris buffers are designed to integrate seamlessly into routine laboratory operations, from protein electrophoresis and analytical biochemistry to method development and quality control testing. All products are manufactured under rigorous quality control standards to ensure pH accuracy, purity, and lot-to-lot consistency. We also offer custom Bis-Tris buffer solutions, including modified concentrations, adjusted pH values, and alternative container formats to meet specialized research or manufacturing requirements.
