Description

ACCURACY CAPABILITIES

• Equipped with a dosing pump that offers an unmatched 40,000 step accuracy
• Save and store up to 100 titration methods (either user-defined or standard). Customize methods to fit specific application needs or testing requirements. Easily program this titrator with standard methods that are in accordance with affiliations like ISO, ASTM, AOAC, AOCS, EPA and more
  
• Operators can program this titrator unit with notification reminders for when to standardize the titrant
• This titrator automatically calculates the average titer value and users can update the nominal concentration in the sample methods with the press of a button
• Track progress in real-time. All important information is shown on the titrator’s large LCD screen. Use the live titration curve during analysis to quickly recognize patterns and spot potential problems 
• Achieve high speed analysis without sacrificing accuracy with dynamic titrant dosing. This occurs by adjusting the volume of titrant dosed according to the mV response from the titrator reaction 
• Get more accurate measurements with automatic drift rate compensation. This corrects the titration calculation to account for the effects of any moisture that may enter the cell
• Choose the endpoint termination criteria based on mV stability times or drift rates with the dual platinum pin electrode
• Maintain data quality with the titration results averaging feature. Ideal for those operators who consistently run replicates of samples. The successive results from a titration method are averaged along with the standard deviation
• Attain a reliable starting baseline with the multistage analysis. This works well for users that test multiple sample types with different methods for each 

 

DURABILITY AND DESIGN DETAILS

• Manufactured to stand up to the harsh solvents and reagents used during titrations
• Made with tough, chemically resistant materials including a strong casing as well as PFTE tubing with glass and stainless-steel components
• Convenient-size, fits perfectly into any lab space 
• Simple to set up and user-friendly. Perfect for labs and businesses that have multiple personnel shift changes throughout the day
• Intuitive screens and menus help operators navigate this titrator unit easily without getting lost in a nest of information

 

SAFE AND IMPORTANT OPERATIONAL FEATURES

Introducing a solid or liquid sample to the titration vessel is simple and straightforward. Includes a quick-remove sample port with a replaceable rubber septum Equipped with a sealed solvent management system and built-in air pumps. Users can move the reagent into waste and refill without physically touching the reagent. This makes testing seamless, eliminates manual chemical handling, and reduces the risk of contact or spills. The sealed solvent management system also mitigates excess moisture from getting into the cell  Standby mode keeps the solvent dry between titrations or when the titrator is not in use   Includes a rechargeable, color-indicating, silica gel desiccant. The desiccant changes color to alert users when its absorption capacity is depleted and needs to be recharged or replaced

REPORTING AND CONNECTION OPTIONS

• Tailor titration reports and store required Good Laboratory Practice (GLP) data
• Export and transfer data to a USB flash drive or PC using the HI900PC application software
• Print titration reports directly from this titrator using a standard parallel printer
• Attach an external keyboard for added versatility
• Connect an analytical balance to the titrator unit with a RS232 serial output. Helps save time with automatic sample weight entry and is ideal for back-weighing purposes

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 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.

Titration Results Averaging

Successive results from a karl fischer titration method may be averaged with recording of the standard deviation.

Titrant Recordkeeping

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.

Selectable Endpoint Criteria

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.

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.

 

Burettes & 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 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.

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.
