With our toximeter we perform ecoxicological tests, ecotoxicity assays, bioassessments and online biomonitoring according to the OECD-guidelines and the European legislation in the water sector. Since 1994 our toximeters have been thoroughly studied and generated numerous scientific peer-reviewed publications.
All versions of our toximeters are based on our in 1994 developed non-optical measuring principle “quadrupole impedance conversion” and operate in freshwater, seawater, sediments and soil without pretreatment of the sample (e.g. by filtration). This principle was chosen as best solution by our clients for their applications in water quality control.
are suitable in the following fields
Multispecies Freshwater Biomonitor
In order to permanently assess in the real time the biological effects of mixtures of toxic substances we developed the MFB as a unique toximeter for you to detect as early warning system unknown non-target chemicals so that measures for environmental protection can be triggered effectively and prevent environmental deterioration and damage. As modular system our toximeter consists of 8-96 sensor channels, highly sensitive software and offers you test chambers for many different indicator species as well as operation for 12V and 230V.
LimCo Biosensor System/ Groundwater Biomonitor
Equipped with 8 sensor channels, an extra power-saving electronics and an alarm software based on 3 different alarm algorithms our LimCo Biosensor System (LBS) represents your reliable early warning system and toximeter for continuous water quality monitoring in real time. For a valid water quality assessment different types of test chambers and chamber arrays for new applications are available, e.g. paired choice chambers for automatic avoidance tests with earthworms, as well as for groundwater biomonitoring with groundwater Crustacea in the laboratory and in the field.
Microimpedance Sensor System
Based on our recent research and development know how with our toximeters the innovative Microimpedance Sensor System (MSS) is working with a particularly high sensitive electronics and microfluidic micro-chambers. This combination allows for using meiofauna from surface and groundwater in both flow-through and recirculating settings. Moreover, the MSS offers you the opportunity to use small indicator species or smaller instars of large species with higher pollution sensitivity, leading to valuable insight in low detection limits for toxic stressors in your water sample.
