Description
HI921 Autosampler for Automatic Titrator
what is Autosampler ?
Autosample is an automatic titration sample holder system.
Autosampler can be use with the HI902C automatic titration .
The HI921 Autosampler suitable for Automatic Titrator can be equipped with more than three pumps to add regent, sample surface and aspiration losses

HI921 Autosampler for Automatic Titrator
Autosampler with 18 beaker tray
with Using of 18 beaker autosampler, device can run up to 18 samples .
the list of benefits of Autosampler:
- 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 deionized 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 includes 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
Green – Steady green – idle, ready to start; flashing green – running
Yellow – Flashing yellow – paused
Red – Error or emergency stopped, or initialising during power on
