WebBuffer EB is the elution buffer used in the QIAquick PCR, Gel Extraction, Nucleotide Removal Kits, and MinElute Kits for DNA cleanup, and the QIAprep Miniprep Kits for small-scale plasmid purification. The purified DNA can also be eluted in TE (10 mM Tris-Cl, 1 mM EDTA, pH 8.0), but the EDTA may inhibit subsequent enzymatic reactions. WebPCR is carried out in a buffer that provides a suitable chemical environment for activity of DNA polymerase. The buffer pH is usually between 8.0 and 9.5 and is often stabilized by Tris-HCl.

WebBuffer solutions are used to calibrate pH meters because they resist changes in pH. When you use a pH meter to measure pH, you want to be sure that if the meter says pH = 7.00, the pH really is 7.00. So you use solutions of known pH and adjust the meter to display those values. They are easily prepared for a given pH.
