Description
Buffer solution pH 7.4 (20 °C) is a special buffer solution according to Hellige for ammonium determination in analytical chemistry. Packed as 1 l in plastic, the solution has a density of approximately 1,08 g/cm³ and a boiling point of 100 °C. The pH value of 7.4 is specified at 20 °C, in line with the Hellige buffer used for ammonium determination. This 1 l plastic pack is intended for laboratory use where a Hellige buffer at pH 7.4 (20 °C) is required. Density of about 1,08 g/cm³ and boiling point 100 °C describe the physical character of the liquid as supplied. The buffer, from manufacturer Carl ROTH, belongs to the special buffer solutions used as analytical chemicals. Laboratories can use the 1 l plastic bottle for ammonium determination work that calls for a Hellige-type buffer at the stated pH and temperature. Buffer solution pH 7.4 (20 °C) combines the Hellige specification, stated density and boiling point, and a 1 l plastic pack for ammonium determination.
