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
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 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
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 its adsorption capacity has depleted and is ready for replacement
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
HI933 automatically adjusts the titration calculation to account for the effects of anyambient humidity entering the titration cell. This provides a more accurate result by correcting for water not present in the
Titration Results Averaging
Successive results from a 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.
Selectable Endpoint Criteria
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.
Interface and Display
Detailed Titration Graphs
A real-time titration curve can be displayed during each titration; this feature is useful when new methods are tested or when a procedure requires optimization.
Interactive Color Display
A large, color LCD screen clearly shows the chosen titration method along with results, units, dosing size, titration volume, drift rate, and mV value.
Simple & Quick Navigation
Virtual key selections present on the display allow for simple and quick navigation between screens and menus without getting lost in a nest of information.
Data and Storage
Customizable Titration Reports
Each titration report is fully customizable so users can ensure they are storing and filing the appropriate data required for their application and procedures.
Flexible GLP Management
All necessary GLP (Good Laboratory Practice) information can be recorded with each sample including: sample identification, company and operator name, date, time, electrode ID codes, and calibration information.
Effortless Data Transfer
Data can easily be transferred to a USB flash drive or PC with the Hanna HI900PC application software. The USB port allows for the transfer of titration methods, titration reports, and software upgrades via USB flash drive.
Methods of Analysis
HI933 can store up to 100 user-defined or standard titration methods. Each method may be customized and optimized for performance based on application and user requirements.
Titration Method Support
Onsite installation, training, and customization is available from one of our Applications or Service experts. Hanna offers continued support via phone or webinar for any questions you might have along the way.
Adaptable Standard Methods
Our technical experts can program and customize standard methods developed by such affiliations as ISO, ASTM, AOAC, AOCS, EPA, and more directly onto your titrator. Ask our Sales Consultants which standard methods are possible with our HI933 Karl Fischer system.
Configurable Balance Interface
Sample size may be automatically entered from any laboratory analytical balance with a RS232 serial output saving time and labor.
Users can print reports directly from the titrator using a standard parallel printer. An external monitor and keyboard may be attached for added versatility, as well as an analytical balance for automatic sample mass entry for titrations.
