产品详细信息

详细说明 (English)

Packaging
5, 25 g in glass bottle
Application
Bromothymol Blue (BTB) is a pH indicator (pKa approx. 7.1) that is used as a biological slide vital stain to define cell walls or nuclei under the microscope. BTB is also a component of several bacterial growth and detection substrates such as cystine lactose electrolyte deficient (CLED/BROLACIN); polymyxin pyruvate egg yolk mannitol bromothymol blue (PEMBA) and MacConkey agar.
