7 EasyLab Expertise Main Technological Expertise Field Liquid Handling (topic of today) Sample preparation & Predilution, Serial Dilution, Plate Filling & Reagent dispensing, Aliquoting, Formulation and ph measurement, Image Analysis Cells based assay reader: Seroneutralisation, Titration, Elispot, SRD, Bactericide, Hemaglutination, (Fluorescence, multiplex, ) Automated Label printing & Sample Management Customized Robotics solution Innovative technologies : Artificial Intelligence, Augmented Reality Computer System Validation (Up to GMP level) 7

8 Liquid Handling : Precision/accuracy qualification Case study : Laval 2015 (Canada) Situation Clinical Lab equipped with 6 TECAN Liquid handling systems Systems are working days and night to produce Clinical results Ecological initiatives in 2015 to save energy Nobody in the Lab the weekend STOP HVAC (air conditioning) in lab WE Canada winter -40 C and summer +40 extreme different environment conditions Issue Suddenly, Assays performed on LH systems on Monday systematically out of range Consequence : No more testing on Monday decrease productivity & trust in automated systems After investigation : Humidity/pressure/temperature required all Monday to recover. No real human sensitivity but LH systems affected. 8

9 Liquid Handling : Environmental impact Partnership TECAN-ARTEL-GSK As global organization EASyLab transfer system/protocol to other GSK sites and countries different weather conditions and to workaround we need : Environment Automatic Liquid Handling parameters adjustment or At least monitor temperature/pressure/humidity for further investigation Partnership between ARTEL-TECAN-GSK to Modelize impact of environment on LH based on Design of Experiment approach where : GSK provided statistical design Tecan provided equipment and liquid handling expertise Artel provided environmental chamber, and conducted testing and data analysis 9

14 QC Kit Verification Plates Lot characterized plates Extensive testing of every plate lot Well dimensions traceable to the National Institute of Standards and Technology, USA (NIST) Bottom diameter (D) and taper angle ( ) are critical to volume calculations 2D barcode on plate boxes carries necessary information about performance, dimensions and lot number D 14

15 How it works - Overview of Dual-Dye Photometric Method Photometric measurement of liquid volume Two dyes measured at two wavelengths Ratiometric calculation of results per well Simultaneous measurement of accuracy & precision per tip Artel s patented dual-dye ratiometric photometry is included in ISO 8655: Part 7 and the measurement results are NIST-Traceable 15

16 Patented dual-dye Ratiometric technology from Artel The Tecan Infinite reader measures absorbance at 520nm and 730nm Based on the optical density (OD) measurements, the absolute volume of pipetted Range Solution is calculated This calculation factors in data gathered from the Calibration and Baseline steps 16

17 QC Kit Software for EVOware Fully integrated with Freedom EVOware, enabling seamless, step-by-step control of the entire workflow. A wizard controls pipetting, shaking, reading, data analysis and reporting, providing a straightforward pass/fail result. 17

18 QC Kit Reporting Is designed to meet quality and regulatory needs with the following reporting options: QC Kit report one page summary of the verification test results and a pass/fail analysis QC Kit extended data report for more detailed, systematic analysis of liquid handling verification results, to be used for troubleshooting and liquid handling optimization 18

19 QC Kit Report OVERALL QC REPORT TO SATISFY QUALITY AND REGULATORY NEEDS Consists of: User Information Instrument information Software version information Pass/Fail requirements Average test results for all channels The reports can be printed or exported to the PDF file format. The data can also be exported as CSVs for further analysis, such as trending or data driven troubleshooting. 19

20 QC Kit Extended Data Report THE AUTOMATICALLY GENERATED PRINTOUTS LISTS THE OVERALL ACCURACY AND PRECISION (CV) AND GIVES VOLUME INFORMATION PER TIP Report shows the overall outcome (pass or fail) Color coding shows results for each individual well at a glance Easy to identify if a tip deviates from the expected volume 20

69 Conclusions 1) Environmental conditions impact any pipetting that incorporates air. 2) Precision was found to be insensitive to temperature and humidity over the testing range. 3) Trueness was found to depend on the environmental conditions a. Trueness should be optimization under the local environmental conditions b. A linear correlation was found between the trueness and the evaporation potential c. Fuller tips are less sensitive c. A stable environment will minimize impact on the business process 4) The QC Kit is unaffected by the environmental conditions. 69

70 Final Note The precision of the Tecan Freedom EVO was found to be insensitive to environmental conditions and performed within manufacturer s limits over the entire range tested in this study (15 C to 30 C and 30% to 80% relative humidity). Note: Tecan specifies the pipetting behavior of the Freedom EVO under controlled environment conditions (T = 20 C to 27 C; relative humidity at 25 C between 30% and 60%). Volumetric performance specifications apply to this controlled limit. For operation outside these limits meeting the manufacturer's specifications for volumetric performance is not guaranteed. 70
