HI933 Volumetric Karl Fischer Titrator Capabilities

HI933 Karl Fischer Titrator

Dynamic Titrant Dosing

The titration speed feature allows for timely and accurate titration results by relating the amount of iodine generated to the mV response from the Karl Fischer reaction.

Drift Rate Compensation

The HI934 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 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 HI934 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

Burette and Dosing

 

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.

Titration Maintenance Agreement

Titration Maintenance Agreement

You’ve made a great choice when you go with Hanna for your titration needs. All it needs is a little TLC, and it will serve you well for years.

All titration equipment requires annual maintenance due to the wearable parts and the harsh chemicals, such as sodium hydroxide, required in many titrations. An annual checkup, calibration, and replacement of burette accessories result in a long instrument life, accurate and precise results, and safe operation.  

As always, Hanna delivers the quality and expertise you need at an affordable price. The Hanna Titration Maintenance Agreement keeps your instrument in optimal working order and ensures that you stay up-to-date on best testing practices. The agreement includes the following services and perks, which keeps your instrument performing at its best:

  1. One (1) onsite calibration, performed for you by certified personnel

  2. One (1) time replacement of wearable parts

  3. Backup of your titration methods

  4. Coverage by the Hanna Loaner Program. When you send your titrator in for service or repair, we will give you one of ours to borrow, with your methods loaded, so that you’ll never be without.

  5. One (1) refresher training by a Hanna expert

  6. 25% off all services, including your install

  7. 5% off all Hanna purchases

  8. Certificate provided to you upon completion

The Hanna titration line enjoys an incredibly low cost of ownership, and the Titration Maintenance Agreement is the cornerstone of that value.
