Description
Buffer solution, technical grade, pH 6,86 is a pH calibration buffer supplied in a 500 ml plastic bottle for technical laboratory use. With a stated pH value of 6,86 and a tolerance of ±0,01 pH, it supports accurate calibration of pH meters and electrodes around the near-neutral range. The preparation is described as technical quality and is supplied with a certificate of analysis; traceability is referenced to NIST. This 500 ml bottle format suits routine multi-point calibration schedules in quality control, research, and teaching laboratories that require a stable intermediate buffer point. Net weight is 0,599 kg and gross weight is 1,599 kg per unit. The buffer from manufacturer Hanna Instruments is intended for pH calibration workflows where technical-grade solutions with documented analysis are preferred. Clear pH labelling and the ±0,01 pH specification help operators select the correct standard alongside acidic and alkaline buffers. The plastic bottle packaging supports everyday bench handling while providing sufficient volume for repeated calibration cycles on portable and benchtop pH systems used in electrochemical measurement setups.
This article belongs on pH buffers & conductivity standards, in Buffers & pH solutions.

Questions about 6.86 pH Value @25°C, (1) 500 mL bottle
What is this article?
6.86 pH Value @25°C, (1) 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.
