Highlights:
- Volumetric KF titration
- Ready to use standard methods for standardization of the titrant and sample titration for 1- and 2-Component KF titrants.
- Statistical functions including average value and relative standard deviation
- Configurable output: Short, Standard with curve, GLP
- Formula editor for individual calculations
- Output of results in ppm,%, mg, μg, mg / l. Unit individually adjustable
- Also suitable for the determination of bromine number and other dead stop titrations such as SO2 in wine and other food products.
- Can be used also for dosing tasks such as sample preparation based on the sample weight.
- The addition of the solvent and the extraction of the titrated sample are carried out by titration stand at the push of a button (Included with all sets)
The TL 7500 with 5, 10 or 20 ml burette 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, drift in µg/mL and µA-value are clearly displayed on the display.
The three USB, two RS 232 and Ethernet interfaces makes the TL 7500 KF 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 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 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 TitriSoft PC software to control the TL 7500 KF. The TitriSoft 3.5P (TZ 3572) comply fully with 21 CFR, Part 11.
