Automate up to 18 Samples
Hanna HI921 and HI922 Autosamplers are automated titration sample handling systems designed for use with the HI932 or HI902C Automatic Titration Systems respectively, making multiple sample titrations quick and easy.
With the Autosampler, up to 18 samples can be run consecutively. Hanna Autosamplers interface directly with the compatible titrator to access titration methods. Once a titration method is established, the user can fully customize the automation sequence of their samples for this method. Sample names and size can be customized or auto-filled with preset values. One beaker can be designated for storage purposes before and after titration sequences; up to three beakers per tray can be designated for an electrode rinse sequence, allowing for sufficient removal of solutions that are hard to clean between each sample titration. During each sample titration, the real-time progress is shown on the Automatic Titrators display. Finished sample results and graphs can be accessed during and after the titrations have finished.
Once the Autosampler sequence is complete, two reports are available for review: a sequence report featuring a table outlining each sample name, beaker position, sample size, and result for the tray, and a detailed titration report for each individual sample, including the graph of the titration data.

HI921 and HI922 Autosampler Features (examples shown on HI922 Autosampler)
The included control panel features operation buttons to allow for manual operation of the Autosampler tray, electrode holder, and any auxiliary pumps. A two-line backlit display on the handheld panel clearly displays status information. Manual control with the control panel is desirable for calibration, sample preparation, and method optimization.
Peristaltic and membrane pumps
Users can add up to three peristaltic pumps or one membrane pump at any time with the user-replaceable pump systems. The peristaltic pumps use high performance plastic that is engineered to be chemically resistant with a long service life. These pumps have a flow greater than 200 mL/min and can be utilized for reagent addition, sample leveling, and waste removal. The membrane pump is a simple plug connection for tubing that has a flow greater than 400 mL/min.
16 or 18 sample tray
These Autosamplers are able to automate samples using a 16-sample tray or an 18-sample tray. The 16-sample tray holds 150 mL beakers; the 18-sample tray holds 100 mL beakers. The Autosampler trays are composed of chemically resistant materials and are removable to allow for easy handling. The dishwasher safe trays provide a quick and simple way for users to clean regularly.
Versatile electrode holder
The durable electrode holder is able to accommodate three 12 mm electrodes, a temperature sensor, one aspiration tube, and five multipurpose tubes. The multipurpose tubes can be utilized for actions such as reagent addition or burette dosing.
Use overhead or built-in magnetic stirrer
Each Autosampler tray has a built-in magnetic stirrer. Users simply need to add a small magnetic stir bar to each beaker to ensure homogeneity during titrations. An optional overhead propeller stirrer can also be installed for use instead of the built-in stirrer. The HI922 allows users to easily adjust the stirring speed of both the built-in and overhead stirrers for optimal use.
The Autosampler consistently tracks the tray position without the need to “home” or calibrate.
The sample trays feature a built-in RFID reader that is able to communicate the tray size and serial number of each tray. Users can have multiple trays, each designated to a specific set of samples. The RFID reader can ensure that the appropriate tray is used each time.
Optical IR beaker detection
An optical IR beam is able to detect the presence or absence of beakers within the sample tray. Users can dictate the Autosampler action if a beaker is missing from the tray during a titration sequence. If a beaker is detected as missing, the Autosampler can skip over the sample or stop the titration sequence.
A USB-compatible barcode reader can be used to associate names with each sample for improved organization of data.
Electrode rinse feature
Up to 3 beakers per tray can be designated for electrode dip/spray rinses.
Sample leveling feature
Automatic leveling for fast preparation of volumetric samples.
Waste removal feature
Aspirate completed samples into a waste container.
Status indicator lights
Highly visible status lights are located on both sides of the HI902C or HI932 Autosampler. These lights correspond to the status indicator on the display and can easily be seen from far away. The lights double as a safety feature, as pressing them at any time will automatically stop the current titration sequence.
