Buffer solution/NBS/DIN - PL 7

Buffer solutions according to DIN 19266-01: 2000 are the most widely used buffer solutions. They are so-called working reference buffer solutions and, due to their composition as listed in the standard, are the best known buffer solutions at all. Standard buffer solutions from WTW are traceably certified to PTB/NIST and therefore safe to use.

The standard buffers in the 250 ml bottles are pH 1.679, pH 4.006, pH 6.865, pH 9.180 and pH 12.47 (PL 2, PL 4, PL 7, PL 9 and PL 12).
