Reagecon's Bromothymol Blue R3 Solution is a high quality Indicator Solution produced from the highest quality raw materials and manufactured and tested under rigorous conditions. For manual titrations; indicator titrant or analyte change colour and this colour change is by far the most important method of end point detection, in such titrations. A high quality indicator solution such as Reagecon's facilitates end point detection, in a clear and unambiguous manner and is an imperative for accurate manual titrimetry.

Reagecon's pH 6.86 at 25°C Equimolal Phosphate 0.05M according to United States Pharmacopoeia (USP) is specified for use in individual United States Pharmacopoeia (USP) Monographs. It is tested by an ISO 17025 Accredited Test Method (A2LA Ref: 6739.03); is NIST traceable and has guaranteed stability throughout its entire shelf life; even after opening the bottle.
