The pH buffers are essential for routine pH meter calibration in order to capture accurate readings. Ready-to-use prepared solutions eliminate the time, expense, and contamination risks of mixing buffers. 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.
