Apera Instruments Buffers AI1109 Editorial Review
The Apera Instruments, LLC-AI1109 8oz. pH Calibration Buffer Solution Kit is a reliable and accurate solution for calibrating pH/ORP electrodes, according to customer reviews. The kit includes pH 4.00, 7.00, and 10.01 buffer solutions, as well as a 4oz 3M KCL storage solution. One customer noted that all the bottles arrived in good condition and were sealed in individual plastic bags. They used the solutions to condition the probe per the manufacturer's instructions and found that the readings were spot-on after calibration. Another customer appreciated the temperature scales on the bottle labels, which helped ensure accurate calibration in their hard water area. The product arrived quickly, and customers found the bottles and packaging to be sturdy. However, one customer received an expired product, and another experienced high pH readings after changing their RO system filters.
