Volumetric Karl Fischer Titrator
fisher bran
For scientists and professionals who need exact water content determination from 0.01 to 100%, the HI903 is a reliable Volumetric Karl Fischer Titrator that gives results in minutes.
Unlike other Karl Fischer titrators, the HI903 features an ultra-high precision dosing system and a specialized burette design for unmatched accuracy.
A Better Volumetric Karl Fischer Titrator Experience
Our friendly technical consultants take pride in helping make your titrator selection easy – every step of the way. Our experts are here to guarantee you have a positive experience, from onsite installation and training to customization and continued support.
Dynamic Titrant Dosing
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.
Drift Rate Compensation
The HI903 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.
Titration Results Averaging
Successive results from a karl fischer titration method may be averaged with recording of the standard deviation.
Titrant Recordkeeping
The HI903’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.
Selectable Endpoint Criteria
The HI903 employs a dual platinum pin electrode for bivoltammetric endpoint determination. Users may choose termination criteria based on mV stability times or drift rates.
Multistage Cell Preparation
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.
View DetailsBurettes & Dosing System
Be confident in your results.
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.
Engineered to be strong
Aspiration and dispensing tubes are constructed of durable, chemically resistant PTFE and feature a light-blocking polyurethane outer sleeve to protect light sensitive reagents.
Anti-Diffusion Dispensing Tip
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.
Titration & Solvent System
Efficient Sample Handling
The HI903 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.
Chemically Resistant Titration Vessel
The glass and PTFE titration cell and fittings are designed to withstand the harsh solvents and reagents involved in Karl Fischer titration.
Sealed Solvent System
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.
Visually Recognizable Desiccant
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.
