Hledali jste: Pufry pH
The pH buffers are essential for routine pH meter calibration to capture accurate pH range of acid or base. Ready-to-use prepared solutions eliminate the time, expense, and contamination risks of mixing buffers. pH buffers can be used to identify weak acid, conjugate base, strong acid, blood pH etc. With colored and colorless pH buffer options available, researchers can efficiently select the correct indicating solution for any test. Powder pillows and sachets permit laboratories to store the concentrated substances for longer time periods without being affected.
