The Metrohm «ready to use» buffer solutions
pH 4.00, pH 7.00 and pH 9.00 are now available in disposable
single sachets. The use of single packed buffer solutions
guarantees that always fresh, contamination-free buffer
solutions are used. The buffer solutions are passed through
a sterile filter so that a shelf life of two years can
be guaranteed. The chemical composition is identical
to the well established Metrohm buffer solutions 6.2307.1X0
in the 500 mL bottles. Naturally, the buffer solutions
in the disposable sachets are fully traceable to NIST
standards.
