Tecan and Artel partner to produce unique, fully integrated QC Kit for Freedom EVO® workstation

6-2-2012. Tecan has partnered with Artel – the worldwide leader in liquid handling quality assurance – to offer the QC Kit, a fully integrated performance verification solution for its Freedom EVO liquid handling workstations. The QC Kit incorporates Artel’s proprietary Ratiometric Photometry™ technology within the Freedom EVO system, enabling collection of precision and accuracy performance data regarding the volumes delivered by every channel of a liquid handling arm, with results fully traceable to international standards. This new tool provides clinical, pharmaceutical and forensic laboratories a simple and reliable way to meet increasing Quality & Regulatory demand for performance verification.
The QC Kit comprises an Infinite® F50 or Infinite 200 PRO microplate reader, a calibrator plate, shaker, barcode scanner and a Freedom EVOware® software add-on, plus a range of co­branded consumables, including characterized verification microplates and color dye solutions. All color dye solutions are traceable to international reference standards, allowing direct comparison of results between different sites and instruments. The liquid handling performance results can be obtained automatically in just 10 to 30 minutes – depending on the workstation configuration – without the need for a carefully controlled testing environment, sample preparation or standard curve generation.

Ratiometric Photometry refers to dual-dye, dual-wavelength absorbance measurements to determine a target volume of sample solution dispensed from a pipette or liquid handler. Two colorimetric dyes, with distinct absorbance maxima at 520 nm (red) and 730 nm (blue), are used to make this measurement possible. Volume measurements are determined by applying the Beer-Lambert Law, which states that the measured absorbance of a dye is proportional to the concentration of a dye, the molar absorptivity of the dye, and the pathlength of the sample holder. If both the molar absorptivities and concentrations of the dyes are known and closely controlled, which is the case with ARTEL Sample Solutions, the law can be used to determine an unknown pathlength traversed by a photometric light beam. By measuring the pathlength through the solution and by knowing the dye concentrations in the ARTEL Sample Solutions, the unknown volume can be calculated through a series of equations.

Tecan offers complete automation for cell-based screening

 

[26-05-2011. Tecan has launched Tecan Sterile purity disposable tips for the Freedom EVO® liquid handling (LiHa) arm, helping to meet the increasing demand for automation in life science research. Previously only available in Tecan Standard or Tecan Pure formats, LiHa disposable tips are now offered in Tecan’s highest purity level, and are ideally suited to high content, cell-based assays and screens, as well as microbiology applications.
Available in 50, 200 and 1,000 μl volume sizes, either as filtered or non-filtered options, each rack of Tecan Sterile LiHa disposable tips is individually packaged in a new SBS­format box with an automation­friendly lid to minimize the risk of contamination. The SBS­format increases flexibility on the worktable, as well as offering higher throughput and longer walkaway times, by ensuring full compatibility with the Freedom EVO’s storage and automation devices.
In accordance with Tecan’s high quality standards, all Tecan Sterile LiHa disposable tips are lot tested by an external, accredited laboratory to ensure tips are sterile and free from human DNA, RNase, DNase, PCR inhibitors and pyrogens/endotoxins. In addition, each box of tips is supplied with a lot specific Certificate of Conformity (CoC) which guarantees purity level specifications and offers full product traceability.
