Introduction

BioGnost’s Buffer tablets are used for preparation of phosphate buffer solutions with stable pH, buffer capacity and low temperature coefficients. Buffer tablets are easy to use and dissolve easily. After that the pH value is automatically set at the necessary level. Besides general use in many histological and cytological methods in which buffer tablets are dissolved in distilled water, they are frequently used in practical hematology in blood smear counting procedures. In that case the buffer solution is essential for preparation of diluted Giemsa/May-Gruenwald/Wright/Leishman solutions and for rinsing stained samples without causing destaining of stained cells.
