The TitraLab 865 gives instant access to routine functions, making it by far the simplest titrator of its generation. Pre-set routines guide you when running analyses, repeating measurements and performing maintenance. The titration curve is easy to follow live on the large graphic display together with electrode and titrant status. Measurements can be automatically sequenced and repeated, ideal for direct measurement followed by a titration.
The titrating burettes offer the highest resolution on the market giving unbeatable accuracy for your potentiometric titrations. Reach end points or determine inflection points even more quickly, whether you are working with sharp or weak curves or running single or multiple IP, detection is fast and reliable. The TitraLab 865 is also the first titrator of its kind to offer full Quality Controls on your results. QC samples can be defined at specific intervals with full traceability and result archiving.
