WebTheir optimal buffering capacity, or range, is defined by the dissociation constant, or ka, of the acid. We commonly discuss buffering capacity in terms of the pKa or the logarithmic constant of ka. We consider the buffering capacity of a specific buffer to be the pKa ± 1. For example, a buffer with a pH of 6.8 has a pH buffering range of 5.8-7.8. WebFlasks are designed to be used in shaking apparatus and will withstand high speed use over 400 rpm without cracking, leaking or showing signs of wear. Shaking and aerating is a critical component to successful bacterial and yeast culture growth. These shaking incubator flasks come individually wrapped to preserve sterility. Read More Compare. 1.
