Highly Accurate pH Buffer Solutions
These pH buffer solutions are excellent and very accurate. I use them to calibrate my pH probe in my aquarium, and they work perfectly every time, ensuring precise readings. The 300ml bottles provide plenty of solution for multiple uses, and the free 100ml of Formulex is a nice bonus. I’m deducting one star because the delivery took longer than expected. However, the quality of the product itself is top-notch and does the job exceptionally well. I would definitely recommend it to anyone looking for reliable pH calibration solutions!

Sensible size bottles of buffer for a good price
Regular calibration of any pH meter with accurate buffer solutions is esssential for getting accurate pH readings. These buffers are supplied in sensible black plastic bottles and the solutions have different colours (pH 7 is green, pH 4 is red) to avoid mix-ups. Much easier than dissolving up powders to prepare your own solutions.
