Description
TW 7450-72 is a sample changer system consisting of the TW 7450 basic unit equipped with sample rack TZ 3972 for 72 samples. The package includes titration head TZ 3974, rod stirrer TZ 1847 and 5 m of FEP tubing, and is designed for operation on 100-240 V mains power. This laboratory instrument supports automated sequential sample presentation for titration and comparable analytical procedures, allowing efficient handling of larger sample series with minimal operator attendance. The complete configuration from manufacturer SI Analytics - a Xylem brand provides a practical platform for integration into existing titration setups. The 72-position rack increases throughput capacity relative to smaller racks, while the dedicated titration head and rod stirrer ensure reliable sample contact and mixing. Chemically resistant FEP tubing facilitates safe transfer of reagents. Net weight is 71 kg, giving a robust base for continuous laboratory use. The system is intended for professional analytical laboratories performing routine multi-sample titration workflows that benefit from automated sample changing.

What is this article?
TW 7450-72, Sample changer TW 7450, basic unit TW 7450 with sample rack TZ 3972 is the article on this page. Luminix Health distributes SI Analytics - a Xylem brand for laboratory use. It sits in pH & electrochemistry accessories, inside pH & electrochemistry, in Lab instruments.
These are the buffer-bottle holders, the electrode storage vials, the cables and the spare junctions. An electrode stored dry that should have been stored wet is a damaged electrode. The accessory has to be the one that electrode's manual names.
A pH meter is a voltmeter on a glass electrode. The voltage tracks hydrogen-ion activity, and the electrode is converted to pH only after it is adjusted with buffers of known value. Conductivity measures how well a solution carries a current, which for dilute salts tracks concentration. Dissolved oxygen and titration are further electrodes on the same idea: a sensor, a standard, and a reading that is only as fresh as the calibration. Buffer values and chemical identity sit on PubChem. Accreditation of the calibration laboratory is the field of BELAC and EURAMET.
