AUTOMATIC FRACTION COLLECTOR (AFC)
Optimise. Automate. Scale When Ready.
The Automatic Fraction Collector (AFC) automates the collection step in qEV isolation. Set the volumes you need, then collect them consistently across runs with less hands-on involvement.
Set your volumes
Set the buffer volume and other collection parameters for each run.
Collect consistently
Collect defined volumes consistently, with collection measured by weight.
Focus elsewhere
Continue with other work in the lab while the AFC handles collection.
Consistent Collection, Run After Run
The AFC brings greater control and repeatability to routine qEV isolation. It measures collected liquid by weight and advances the carousel automatically, reducing inaccuracies associated with manual collection. Apply the same collection parameters across runs, then focus on other work in the lab while collection proceeds.
Set the Collection That Suits Your Sample
Adjust buffer volume, fraction volume and fraction number directly from the touchscreen. Your purified collection volume (PCV) is the volume of qEV eluate containing your highly purified particles of interest. To identify the optimal PCV for your experiment, collect small-increment fractions and examine the elution profile in detail. Once you've refined your PCV, collect it into a single vessel where supported, removing the need to pool fractions manually.
How the AFC Works
Attach a compatible RFID-tagged qEV column and the AFC identifies it, then displays the relevant default collection settings. Adjust the parameters from the touchscreen and begin collection. The AFC measures each fraction by weight and advances the carousel automatically, while LED lights provide clear visual feedback. The reversible carousel supports 1.5 mL, 2 mL and 5 mL collection vessels, depending on the qEV column in use.

Scale at the Level Your Lab Needs
Sample numbers and sample volumes grow at different rates, and they need different instruments. Most qEV workflows start on an AFC, where fraction-level control lets you resolve your collection parameters in detail. Those parameters are what you carry forward when you scale up.

SCALE BY SAMPLE NUMBER
A robotic liquid handler for processing 24 samples in parallel. Fast-track processing, while keeping your qEV workflow compact and configurable.
Multiply Your Throughput
The qEV Isolation platform gives you several pathways to scale, and adding AFCs is one of them. Running multiple units side by side brings bulk pricing and multiplies your throughput, with the option to dedicate each instrument to a different method.

The following qEV columns can be used with the AFC: qEVsingle, qEVoriginal, qEV1, qEV2 and qEV10. The qEV100 and larger customised qEV columns are not AFC-compatible.
Most ‘raw’ samples cannot be directly run on qEV columns without prior preparation steps to remove large particulate matter. qEV user manuals provide recommendations on how to prepare your sample appropriately.
Yes, we have a range of technical and application notes available at the Izon Support Centre; you can also browse our website for deep-dives into special considerations for the isolation of EVs from blood (including guidance on which anticoagulant to use) urine, CSF, and reproductive tract fluids.
The type you choose will depend on the sensitivity required for your application. We recommend a chromogenic protein assay for protein quantification, such as a Bradford, Lowry or BCA assay.
Load the column with PBS containing a bactericide or bacteriostatic agent (e.g., 0.05% w/v sodium azide or 0.05% ProClin 200), or 20% ethanol. Column cleaning and storage instructions are provided in qEV User Manuals.
