Tris solutions are high-purity buffering reagents used to maintain stable pH in molecular biology, protein chemistry, electrophoresis, immunoassay, analytical, and bioprocessing workflows.

Tris base is the unprotonated, free-base compound, while Tris-HCl is the pH-adjusted, acidified form. We sell both Tris Base and Tris-HCl solutions, as well as Tris-based buffer formulations, which typically combine Tris-HCl (at a specific pH) with other components, such as salts or chaotropic reagents, to achieve specific chemical conditions necessary for molecular biology, biochemical, or bioprocessing applications.

All Tris solutions are prepared using high-purity raw materials under controlled conditions. Standard assays for RUO buffers and reagents include pH, conductivity, osmolality, density, and top spread sterility. To meet the requirements for your finished good specifications, we can also perform custom assays, including endotoxin, DNase, RNase, protease, PCR, microbial enumeration, and compendial sterility testing.

Yes, COAs, SDS files, and full quality documentation can be downloaded or requested to provide complete traceability and regulatory support.

Tris solutions should be stored at the recommended temperature for your specific formulation—typically room temperature or 2-8°C—and handled aseptically to prevent contamination or pH drift.

Yes, we offer custom pH adjustments, salt concentrations, reagent additives, and container formats, including the option to manufacture with customer-supplied raw materials. Learn more about our custom process or start a custom order.
