For scientists and professionals who need exact water content determination from 0.01 to 100%, our new generation of the Volumetric Karl Fischer Titrator is engineered to meet or exceed your technical requirements while delivering a lower cost of ownership. With cutting-edge features packed into a compact design, this titrator delivers accurate results and requires less space in the lab. Get accurate water content determination at the push of a button. Designed for the modern lab, this karl fischer titrator is the perfect fit for your testing environment.
The dynamic dosing feature allows for timely and accurate titration results by relating the titrant volume dosed to the mV response from the titration reaction. This provides for larger doses near the beginning of a titration and smaller, more precise doses near the titration endpoint.
The HI933 Volumetric Karl Fischer Titrator automatically adjusts the titration calculation to account for the effects of any ambient humidity entering the titration cell. This provides a more accurate result by correcting for water not present in the actual sample.
Successive results from a karl fischer titration method may be averaged with recording of the standard deviation.
The HI933’s titrant database can store information for up to 20 titrants. The database may be programmed to remind a user when to standardize their titrant, reducing error in analysis.
The HI933 employs a dual platinum pin electrode for bivoltammetric endpoint determination. Users may choose termination criteria based on mV stability times or drift rates.
A pre-titration stage eliminates residual water present in the solvent and the cell, providing a reliable baseline start to analysis. Standby mode then keeps the solvent dry between titrations and when the titrator is not in use.
Our unmatched 40, 000 step piston driven dosing pump is capable of dosing extremely small and highly accurate volumes of reagent, helping you achieve a very precise endpoint.
Aspiration and dispensing tubes are constructed of durable, chemically resistant PTFE and feature a light-blocking polyurethane outer sleeve to protect light sensitive reagents.
A specially designed glass dispensing tip delivers titrant precisely into high turbulence mixing zones, ensuring a rapid reaction. Its angular construction helps prevent titrant from diffusing into the sample solvent.
The HI933 features a quick-remove sample port with a replaceable rubber septum allowing for fast and easy sample introduction to the titration vessel. An integrated magnetic stirrer ensures homogeneity for an accurate and speedy reaction.
The glass and PTFE titration cell and fittings are designed to withstand the harsh solvents and reagents involved in Karl Fischer titration.
The titration vessel is completely sealed to minimize exposure to ambient humidity, keep the system dry, and reduce titrant consumption while saving time between titrations. Solvent may be exchanged in a matter of seconds without opening the titration vessel.
A rechargeable, color-indicating, silica gel desiccant prevents the ingress of ambient humidity into the sealed system while maintaining full titrator functionality. The desiccant color change allows a user to recognize when it’s adsorption capacity has depleted and is ready for replacement or recharging.
Our large color display shows you everything you need to know during testing.
Our live titration curve helps you quickly recognize patterns and problems that may arise during your analysis.
Custom keys allow you to clearly navigate between screens so you don’t get lost.
Final reports are customizable so you can make sure you are viewing and storing your most important information.
Our software allows you to record full GLP (Good Laboratory Practice) data so there is no need to compromise the quality of your results.
Use our software or a USB to conveniently transfer files between your titrator and computer.
You can print reports directly from the titrator with a connected printer and conveniently view results with a connected monitor.
Connect the devices that help you most, whether it be an analytical balance for automatic sample entry or a printer for your reports.
