Titration is a quantitative chemical analysis technique used to determine the concentration of an unknown solution by reacting it with a solution of known concentration. The process involves gradually adding the known solution (called the titrant) to the unknown solution (called the analyte) until a reaction reaches its equivalence point, where the two substances have reacted in a precise ratio.

There are different types of titration, including:

• Acid-Base Titration: Used to determine the concentration of an acid or base using an indicator that changes color at the equivalence point.
• Redox Titration: Involves oxidation-reduction reactions, often using substances like potassium permanganate.
• Complexometric Titration: Used to determine metal ions in a solution, often using EDTA.
• Precipitation Titration: Based on the formation of an insoluble precipitate, such as silver chloride in chloride determination.

Titration is widely used in laboratory and industrial applications, including pharmaceuticals, food science, and environmental analysis. Given your interest in precision instruments and measurement tools, you might find titration fascinating in its role in osmometry and other analytical techniques.

With its performance spectrum, the TitroLine® 7000 is the ideal starting device for potentiometric titration with potential for expansion and automation. Thanks to the high-resolution and precise pH/ mV and “dead-stop” measuring interface, it is possible to determine a wide range of parameters quickly, reliable and accurate.

The TitroLine® 7000 can be used in all industries such as the chemical, petrochemical, pharmaceutical as well as the food and beverage industry and education. Also well usable for the water and wastewater industry.

The TitroLine® 7000 with has an exceptional high visibility full color graphic display which allows viewing even at extreme angles. The titration curve, but also other information such as ml, pH/mV/µA and temperature are clearly displayed on the display.

The three USB, two RS 232 and Ethernet interfaces makes the TitroLine® 7000 highly communicative. Various USB devices such as printers, barcode readers, keyboards can be connected. Analytical balances, PC and other SI Analytics devices such as the autosampler TW 7200 and other SI Analytics devices can be connected via the RS-232 interfaces. The Ethernet interface allows data to be stored on a directly connected USB stick in PDF and CSV format as well as on shared network directories.

The TitroLine 7000 can be used as a stand-alone instrument, but can also be subsequently expanded to a complex system for high sample throughput by adding additional TITRONIC 300 and 500 piston burettes, TitriSoft 3.5/3.5 P software and TW 7200 and TW 7450 sample changers.

The parameters can be customized in each of the up to 50 methods. Through the user/password management, each user can be assigned individual rights. If you need even more methods or want to manage the data on a PC, you can use the PC software TitriSoft 3.5 (TZ 3571) to control the TL 7500 KF. The TitriSoft 3.5P (TZ 3572) comply fully with 21 CFR, Part 11.
