Integrated immunoassay solutions

Verified performance

The performance of each immunoassay is individually verified, and offers excellent correlation to manual testing. The portfolio is continuously growing, and covers both diagnostics and research applications.

Efficient and safe processing

Processing complete diagnostic panels in a single run enhances reproducibility, ensuring greater confidence in results.

In this example, 17 different assays are performed across 10 microplates, including predilution, in under five hours.

Freedom to operate

The Freedom EVOlyzer can be configured for high throughput analysis of over 500 samples or mixed processing of up to 20 different assays per run, according to your workflow needs.

With optional sample dilution, plate preparation and archiving, the system offers true sample-to-result immunoassay capabilities and beyond.

When time matters

Plate-based immunoassays are robust, but pipetting speed still matters if full 96-well microplates need to be processed. Tecan offers instruments with a choice of two, four or eight pipetting channels, ensuring consistent pipetting and preventing OD drift across a plate. Typical CVs for assays processed on the Freedom EVOlyzer are ≤3.5 %.

The best of Tecan’s liquid handling knowhow with the 8 Plus 1 Access liquid handling arm:

• Reliable liquid level detection, down to 50 μl for conductive liquids
• Large volume range – from 2-1,000 μl
• Efficient multi-dispensing with 1,000 μl tips
• Freedom to pipette into 96- or 384-well SLAS­format plates
• Access any labware format using a single channel

Fast and precise pipetting to match your application needs

Efficient liquid handling

With up to two independent liquid handling arms, samples and reagents can be pipetted in parallel, eliminating any processing bottlenecks. One arm can pipette the next sample batch while the initial sample set is incubating, using the second liquid handling arm to add reagents. The addition of up to two HydroFlex™ washers further improves throughput.

Real-time quality control of liquid transfers

Process security features – such as Pressure Monitored Pipetting (PMP™) and cLLD – improve efficiency and quality by detecting and handling sample processing errors, reducing the number of sample reruns.

Easy-to-use touchscreen interface for daily operation

The TouchTools™ graphical interface allows the operator to select the assay or panel to run, then guides them through the loading of samples, reagents and assay plates, as well as the performance of any maintenance steps.

The software also provides real-time feedback, showing where each assay plate is in its schedule, helping operators to perform any interventions required.

Assays can be grouped into panels that can either be run together in batches, or selectively when a job list is available from the LIMS. The Sample Distribution Wizard and easy-to-use, drag and drop process editor help the user to set up incubations, reagent additions, wash steps and analyses.

Freedom EVOware Plus

An intuitive graphical user interface and an integrated scheduler for multi-plate assays help to maximize throughput and optimize resource use.

• The scheduler lets you handle variable workloads and times by supporting continuous sample loading and ensuring turnaround times are never compromised
• Run multiple processes in parallel
• Simple definition of complex processes with a drag and drop process editor

Customized for efficiency, safety and usability

The software enables you to define all processing steps before, during and after any run, with individual start-up, maintenance and preparation protocols based on your instrument set-up and workflow requirements.

Robust pipetting

PMP calculates a theoretical pressure curve for each pipetting activity and compares it in real time to the measured curve. If one or more fitting parameters are ‘out of range’, the system flags an error. Extensive error handling options prevent invalid runs and the waste of reagents and consumables.
