Description
Thiourea-HCl is a specialised cleaning solution intended for the maintenance of diaphragms on laboratory measuring instruments. The 250 ml pack is suited to routine care of electrode systems where diaphragm performance can be affected by deposits from sample matrices. It has a density of approximately 1,02 g/cm³ and carries UN number 1789 for transport identification. At a pack weight of 0,300 kg, the bottle is practical for scheduled cleaning cycles in analytical and process laboratories. Offered by manufacturer Mettler-Toledo within its range of maintenance and calibration solutions, this thiourea-HCl preparation supports diaphragm cleaning steps that help restore reliable junction behaviour and measurement stability. Laboratories handling frequent pH or ion measurements can incorporate the solution into standard electrode-care procedures alongside other approved maintenance fluids. The defined density and ready-to-use 250 ml format simplify dosing and storage organisation on the instrument bench. Apply in accordance with the instrument manufacturer’s cleaning instructions for diaphragms to maintain consistent sensor function in research, quality control and routine laboratory measurement workflows.
This article is part of pH electrodes & sensors, in pH & electrochemistry.

Questions about Thiourea - HCl, for cleaning, diaphragms, 250 ml
What is this article?
Thiourea - HCl, for cleaning, diaphragms, 250 ml is the article on this page. Luminix Health distributes Mettler-Toledo for laboratory use. It sits in pH electrodes & sensors, inside pH & electrochemistry, in Lab instruments.
A pH electrode is a glass membrane and a reference. It is a consumable: the glass ages, the junction clogs, and the reading drifts. A refillable electrode and a gel electrode differ in how they are maintained. The connector has to match the meter. The electrode, not the meter, is usually what is wrong.
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.
Which category should I open next?
