Easy maintenance and reliable service Flushing of the system and routine replacement of the tubing is made easy by the intuitive design of Crocodile. Trained technical staff is available to help if needed, and after-warranty service agreements are available in most geographical locations to ensure trouble-free operation over the lifetime of the instrument. An open system Crocodile will adapt to any ELISA format, including sandwich, competitive, or other. Reagent bottles of any shape and size are accommodated by the carefully designed and tested bottle holders. Validation made easy The validation performance of Crocodile is supported by our 3Q Package: Installation Qualification, Operation Qualification and Performance Qualification steps are performed according to detailed instructions provided. The results are documented in checklists according to the specific features of the instrument. Regulatory compliance Crocodile has been developed according to the most stringent regulations in the industry: DIN ISO Every step was accompanied by a thorough riskanalysis. Selection of raw materials and the assembly process are performed under strict observation of released procedures and processes. After final assembly, every individual unit has undergone several days of extensive testing and will be accompanied by a certificate of analysis stating compliance with specifications. PC-Software The user friendly software easily adapts to any ELISA protocol. The five different functions can be aligned in any sequence, one or several times each (for example one to four dispensing steps or multiple washing steps). Setting of each step is flexible and intuitive. Once you have chosen an assay protocol, the screen will show a graphic of the entire assay schedule, as it will be performed by Crocodile.

5 Sirius Single Tube Luminometer Highest Performance Utmost Flexibility

6 Sirius Highest Sensitivity and Linearity Concept Sirius can be employed according to the individual needs of each user. In its basic configuration the luminometer is ready for standard measurements. Sirius can be upgraded to form a powerful measurement system for any luminescence application. The Sirius luminometer measures standard glow chemistry of single samples from a variety of sample formats. For flash chemistry, and to make operation more convenient, the instrument can be formatted with one or two built-in automatic reagent injectors. In stand-alone mode, the built-in microprocessor software supports four protocols for data evaluation, including background subtraction capabilities and replicate management, as well as printer output. Modular PC-Software further enhances performance by organizing the measurement dialog and data evaluation. Applications Sirius is the perfect choice for all luminescent flash and glow applications performed in single sample format, for example: Reporter gene assays, including dual-reporter assays Cell proliferation, cytotoxicity and biomass assays Apoptosis assay ATP assays Ca 2+ measurements and aequorin-based assays Cellular luminescence/reactive oxygen species Environmental toxicity and mutagenicity assays Sirius supports a variety of sample formats

7 Closing the sample drawer initiates measurement automatically Photon Counting Detector Sirius Luminometer features advanced photoncounting electronics along with a highly sensitive detector. It provides the lowest signal background and highest linearity covering 6 decades. No cumbersome internal calibration is required and no gain switch is needed. Light collection is maximized through both the proximity of the sample to the detector and the use of optimized light reflectors surrounding the sample vial. As a result, reporter gene assays using firefly luciferase can now detect less than 1000 molecules of the enzyme with the Sirius Luminometer. The Sirius Luminometer combines a very small footprint with excellent performance and outstanding ease of use. The retractable drawer slides the sample into the measurement chamber. Due to the unique design, a variety of sample formats can be accommodated. It is not necessary to press any key to process the samples, in stand-alone or in PC-operation. Injection System Sirius is available with up to two high-precision reagent injectors. Variable injection volumes can be set from 20 to 300 µl. Flexible speed settings and precise injector positioning allow homogenous mixing of reagents for every type of sample. Short reagent lines and the back-pumping option guarantee the most economical utilization of valuable reagents. Sirius is equipped with reliable, bellow-type pumps. Selection of chemically inert materials assures the injectors are virtually maintenance-free. Sirius will detect presence of a sample vial prior to injection, to avoid unintended injection into an empty sample chamber. Stand-alone Operation Sirius is equipped with on-board microprocessor software for instrument control, data calculation and printer output. In stand-alone mode Sirius supports four protocols designed to meet the needs of state of the art luminescence assays. In addition to the Raw Data protocol, which allows standard measurements in a row, Single Assay, Dual Assay and Cut-off Assay are available, supporting predefined measurement sequences, data evaluation and printer output.

9 Sirius Intuitive & Powerful PC Software Basic Module Protocol Manager Program Structure The PC program is structured in protocol format. This allows automation of all steps from the definition of measurement parameters to the reporting of final results. The user can define customized protocols for immediate use or store them for later availability. The measurement results are presented as tables and graphs (where applicable), both on screen and as printouts. You may save results, export them as text files, or import them into Microsoft Excel. Basic Module The basic module includes the Protocol Manager and the standard function Quick Measurement. The protocol is always ready to measure. The delay and measurement time settings are the only functions that may be modified from the default menu. Data is transferred into a single column spreadsheet and may be saved in different formats and printed out in a report. Measurement screen On-line display of both data table and graph Additional protocol types Single Assay Protocol allowing measurement of several samples, with replicates, calculation of average and precision. Automatic background subtraction is available. The background applied can be measured or entered manually. Dual Assay Protocol allowing measurement of one sample with two reagents, such as a dual luciferase assay and ATP measurements with standard spiking. The two measurements are the basis for the final result, which is calculated by a selectable mathematical operation (5 options). Single Kinetics Protocol allowing measurement of the time trend of a luminescent reaction; for one sample, with or without replicates. Measurement results are presented as data table and graph. Additional graph functions: Smoothing, logarithmic scale or selectable scale, integration in zoomed range. Multiple Kinetics Protocol used to measure several samples in parallel. It is designated for kinetics lasting several minutes and longer. The Software guides the operator through samples change procedure. It rearranges the individual data points into data tables and graphical displays. Cut-off Assay Measurement results are categorized, typically with reference to positive and negative samples, into positive, negative and ±.
