产品描述

Application

TES is a physiological Good′s buffer (pH 74.-7.9) used in biological research applications. It is often compared to other Good′s buffers for chemistry and optimal performance in a given system.

Other Notes

Hydrogen ion buffer for biological research^[1]; Suitable buffer for epidermal cell growth at pH 7.4-7.9 where additional buffering capacity is required^[2]
