Full Description Specification

This high quality system makes the titration of multiple samples quick and easy.

  • For a full demonstration, call today on 01525 850855 to make an appointment with one of our titration experts.

Using the autosampler, up to 18 samples can be run consecutively. The HI-921 autosampler also interfaces directly with the HI-902C to access titration methods. Once a method is established, the user can customise the automation sequence samples for the method. Sample names and size can be customised or auto filled in with preset values.

  • Use up to three peristaltic pumps for reagents addition, sample levelling, and waste aspiration
  • Control panel allows for manual operation of the motors and pumps
  • Features sample levelling, built-in magnetic stirrer, reagent addition, electrode rinse feature
  • USB interface with compatible barcode reader and built-in RFID for each tray

Once the autosampler sequence is complete, two reports are available for review:

  • Sequence report with a table outlining each sample name, beaker position, sample size, and result for the tray
  • Detailed titration report for each individual sample, including the graph of the titration data

More benefits:

  • Flexible, accurate detection of the titration endpoint with HI-902C potentiometric titrator
  • Automation of up to 18 samples per tray – 16 sample tray holds 150ml beakers; 18 sample tray holds 100ml beakers
  • Absolute encoder in sample tray – The autosampler always knows the tray position. It never needs calibration and never needs to “home”
  • Electrode rinse feature – up to 3 beakers per tray can be designated for electrode dip rinses; a primary, secondary and tertiary rinse.
  • Automatic addition of reagents or deionised water to the sample beaker by peristaltic pump
  • Control panel for manual operation of motors and pumps (included)
  • Built-in magnetic stirrer or optional overhead propeller stirrer
  • Barcode reader interface for easy sample tracking – USB barcode reader interface for easy sample identification
  • Built-in RFID in each tray, communicating tray serial number and number of beakers it holds
  • Optical IR beam detects presence or absence of beakers in the tray – ensures the autosampler doesn’t proceed with titration if a beaker is missing
  • USB interface – use with barcode reader; field upgradable software
  • Sample trays made of chemically-resistant materials are removable, easy to clean and dishwasher safe
  • Electrode holder can accommodate 3 x 12mm electrodes, temperature sensor, 1 aspiration tube, and 5 multipurpose tubes (reagent addition, burette dosing) – Allows user to switch between methods without physically switching electrodes
  • Real time progress of the sequence and results shown on the HI-902 titrator screen
  • Integrated peristaltic (up to 3) pump
  • Sample levelling feature – automatic levelling for fast preparation of volumetric samples
  • Waste removal feature – Aspirate completed samples into a waste container

The Autosampler can include up to three peristaltic pumps. The pump system has a simple install process and can be connected without the need of a technician.

  • Up to 3 peristaltic pumps can be added at any time
  • User replaceable pump systems
  • Peristaltic – uses high performance plastic engineering to be chemically resistant, with long service life. Resistant to temperature fluctuations; Reagent addition, sample levelling, waste removal; greater than 200 mL/min flow.

Status indicator lights

Easy to see status lights to the top left and right of the autosampler. These can be seen from far away and also correspond to the status indicator on the HI-902C LCD. These lights double as a safety feature – pressing them at any time will automatically stop any titration process.

Green – Steady green – idle, ready to start; flashing green – running

Yellow – Flashing yellow – paused

Red – Error or emergency stopped, or initialising during power on
