Biopharm Buffers Editorial Review
The Biopharm pH Buffer Calibration Solution Kit is an excellent product for calibrating various pH meters. The kit comes with three bottles of different pH levels (4.00, 7.00, and 10.00), each in a 500 ml bottle. The bottles are color-coded for easy identification, and the solution is NIST traceable. The product also comes with certification papers at no additional charge. The solutions are accurate, and the kit provides rapid calibration of meters. The bottles are labelled with expiration dates, and the shelf life after opening is one year. There is some negative feedback about the leaking bottle of pH 7.00 buffer, but the issue is resolved by the fact that the bottle was sealed in a plastic pouch to protect the packaging from getting wet.
