Description
Buffer solution pH 1,68 is a ready-to-use calibration standard for precise pH meter and electrode adjustment in the strongly acidic range. This standard-quality buffer provides an accuracy of ±0,01 pH and is filled in a 500 ml plastic bottle, offering a practical working volume for frequent laboratory calibrations. The defined value of pH 1,68 supports reliable instrument verification where low-pH reference points are required. Traceability to NIST underpins consistent reference behaviour for quality control, analytical routines, and process checks. Supplied by manufacturer Hanna Instruments, the solution is intended for straightforward pH calibration workflows without additional preparation steps. The 500 ml bottle format suits shared benches and multi-user environments where a larger reservoir is preferred over single-use portions. Net weight is 0,89 kg and gross weight is 1,89 kg for the complete unit. Laboratories that routinely confirm acidic-range performance can use this clearly specified pH 1,68 buffer to help maintain measurement reproducibility and confidence in daily electrode calibration.
This article is part of pH buffers & conductivity standards, in Buffers & pH solutions.

Questions about 1.68 pH Value @25°C, 500 mL bottle
What is this article?
1.68 pH Value @25°C, 500 mL bottle is the article on this page. Luminix Health distributes Hanna Instruments for laboratory use. It sits in pH buffers & conductivity standards, inside Buffers & pH solutions, in Lab chemicals.
A pH buffer for calibration has a stated pH at a stated temperature, often traceable. A conductivity standard has a stated conductivity. They are not general reagents and they should not be poured back into the bottle. The temperature of the measurement has to be the temperature on the label, or the meter has to compensate.
A buffer resists a change in pH when a little acid or base is added. It does that because a weak acid and its conjugate base are both present. A pH buffer used to calibrate a meter has a stated value at a stated temperature. A biological buffer such as Tris or HEPES is chosen because it holds the pH of a living system and does not poison it. Conductivity standards are the sister articles for a conductivity meter. The ions are on PubChem. Electrode calibration practice sits with EURAMET and BELAC.
