HI903 Karl Fischer Volumetric Titrator for Moisture Determination The HI903 Karl Fischer Volumetric Titrator is an automatic titrator that complements our wide range of products dedicated to efficient and accurate laboratory analysis. The HI903 analyzes for water content ranging from 100 ppm to 100%. This powerful titrator automatically dispenses the titrant, detects the endpoint, and performs all necessary calculations and graphing. Burette and Dosing System Precision Dosing Pump Our unmatched 40,000 step piston driven pump is capable of delivering as little as 0.125 µL of titrant accurately and precisely. 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. Chemically Resistant Tubing and Syringe Aspiration and dispensing tubes are constructed of durable, chemically resistant PTFE and feature a light-blocking polyurethane outer sleeve to protect light sensitive reagents. Titration and 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 reactions. 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.
