Hanna Instruments Automatic Titration Systems

• Automatic titrator dedicated to quick and accurate laboratory analysis. Can perform acid/base, potentiometric, ORP, complexometric, precipitation, back titrations and titre determinations.
• Dispenses the titrant, detects the endpoint and performs all necessary calculations automatically.
• Supports up to 100 methods, standard or user defined.
• When powered on, the instrument initiates an internal diagnostics check and then readies itself for the first titration of the day.
• Potentiometric titrations: acid-base (pH or mV mode), redox, precipitation, complexometric, non-aqueous, ion-selective, argentometric, back titrations and titre determination.
• Burette sizes: 5ml, 10ml and 25ml. Burette resolution: 1/40,000. Burette size is automatically recognized when inserted into the unit.
• Flow rate: user-selectable from 0.1ml/min to 2 x burette volumes/min.
• Display: 5.7" (320 x 240 pixels) backlit color LCD.
• Real time and stored graphs: mV-volume or pH-volume titration curve, 1st derivative curve or 2nd derivative curve, in pH mode, mV mode or ISE mode; pH/mV/concentration values versus time-datalogging results.
• End-point determination: equivalence point (1st or 2nd derivative) or fixed pH/mV value.
• At the end of the titration, all data including the graph are automatically stored in memory and can be copied via the built-in USB drive or through direct connection with a PC.
• All GLP information from each sample can be stored, including ID number, date and time of analysis, electrode ID code and last calibration date.
• Calibration: (pH) up to 5 point calibration, 8 standard buffers and 5 custom buffers; (mV) single point offset; (ISE) up to 5 point calibration, 7 standard solutions and 5 user defined standards.
• Programmable stirrer (included): propeller type, 100-2500rpm, automatically held within 10% of the set value, resolution 100rpm.
• Field upgradable software.
• Multilingual support, including English, Portuguese, Spanish.
• Store up to 100 titration and pH/mV/ISE reports.
• Users can connect pH, ORP or ISE electrodes to the unit, as well as create a complete workstation with PC, monitor, keyboard and printer.
• USB port allows for the transfer of methods and reports to a PC or another titrator via USB flash drive. RS232 port allows direct communication to an analytical laboratory balance.
• USB host (side): flash drive compatibility for transfers of methods and reports. Peripherals (rear): connections for VGA display, PC keyboard, parallel printer, USB device input, RS232, interface for future expansion.
• Temperatures (operating) 10 to 40°C (50 to 104°F), up to 95% RH; (storage) -20 to 70°C (-4 to 158°F), up to 95% RH. Temperature compensation: manual or automatic (ATC).
• Supplied with stirrer with stand, 25ml glass burette, dosing pump drive, temperature sensor, USB cable, 256Mb USB flash drive and PC software.
• Dimensions: 15.3 x 13.8 x 14.9". Weight: 10kg (22lbs) with one pump and stirrer assembly.
• Power: 115V.

Four working modes: potentiometric titrator, pH meter, mV meter, and ISE meter:

MODES:
Potentiometric Titrator:

• Linked titration methods allow 2 methods to run in sequence.
• Acid/base, non-aqueous, ORP, complexation, back, precipitation titrations and titre determination can be performed.
• Supports up to 100 titration methods (standard and user defined).
• Supplied standard methods pack or create your own.
• Titration graph can be displayed on-screen and saved as bitmap.
• Choice of endpoint detection: equivalence point (1st or 2nd derivative) or fixed pH/mV value.
• Reminders for titrant age and standardization expiration.
• Multiple end-point titrations with multiple molecular weights and reaction ratios.
• Two sensor inputs with the addition of a second analog board.
• Supports 2 burette dosing pumps with the ability to perform back titrations.
• Clip-Lock™ exchangeable burette system enables users to exchange burettes in a matter of seconds.
• 25ml precision ground glass syringe with PTFE plunger.
• 40,000 step screw drive, piston dosing pump.
• 3-way motor driven valve.
• PTFE burette tubing with polyurethane tube jacketing.

pH meter:

• Full featured research grade pH meter.
• Automatic temperature compensation (ATC).
• Up to 5 calibration points with automatic recognition of standard buffers.
• Up to 5 custom buffers can be used for calibration.

mV (ORP) Meter:

• Relative mV calibration.

ISE Meter:

• Numerous concentration units including: mol/L, mmol/L, mg/L, mg/mL, µg/L, %, ppt, ppm, g/L, and user defined.
• Up to 5 calibration points with 5 custom standards.

Clip-Lock™ Exchangeable Burette System:

• With Clip-Lock™, it only takes a few seconds to exchange the reagent burettes to perform a different titration.
• Prevents cross contamination while reducing loss of time and reagents.
• Having several prepared burettes on hand will make the Hanna unit one of the fastest and more versatile titration systems on the market.
