State-of-the-art Direct Read Discrete Analyzer for automated determination of acute toxicity in water samples based on bioluminescent bacteria, up to 30 tests per hour throughput.
EASYCHEM TOX Early Warning is a on-line automated platform equipped with color touchscreen LCD and housed in an industrial cabinet, comprising a refrigerated compartment, for bacteria, reagents, calibrants and controls. A mechanical arm for aspiration, transferring and dispensing of reagents and samples and a thermostated reaction plate with 80 positions are incorporated with a luminometer, integrated with an automated cuvette washing station.
Easychem TOX Early Warning: acute toxicity automatic measurement with luminescent bacteria
In order to enable an extended time of use of rehydrated cultures by up to ten days, proprietary bioluminescent bacteria were selected, grown, stabilized and lyophilized according to standard methods. Thus, for the required period, the microorganisms preserve a measurable bioluminescence signal and an unaltered sensitivity to different types of reference compounds defined in ISO and GB-T standards, such as zinc sulphate and mercury Chloride. The system is programmed to manage several bacterial vials in succession, thus enabling an high frequency measurement for one month or up to three months of unattended operation with lower measurement frequency.
Fully automated for unattended toxicity monitoringTiming and frequency of analytical cycles, limits and parameters of quality controls are programmable by the operator and managed automatically. The continuous measurement of blanks and samples at pre-defined time intervals of about 40 seconds, results in the generation of inhibition kinetics, which allow to achieve, from the very beginning of the analysis, preliminary information on the level of sample contamination. Following a toxicity alert, the system is able to react immediately by automatically replicating samples and performing control checks to confirm identified toxicity, significantly reducing the occurrence of false positives.
