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 content of the sachets is sterilized by sterile filtration 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.
The following units are available:
6.2307.200 Buffer solution pH 4.00 (25 °C), 30 x 30 mL, shelf life 2 years, traceable to NIST
6.2307.210 Buffer solution pH 7.00 (25 °C), 30 x 30 mL, shelf life 2 years, traceable to NIST
6.2307.220 Buffer solution pH 9.00 (25 °C), 30 x 30 mL, shelf life 2 years, traceable to NIST
6.2307.230 Buffer solutions pH 4.00 / 7.00 / 9.00, 3 x 10 x 30 mL, shelf life 2 years, traceable to NIST
