Product Brochure

WMicrotracker ONE is optimized for measurements of animals cultured in a liquid medium by using a 96- or 384-well plate format. Compatible with most small animal species [from 100 um to 3 mm size]. Useful for Drug screening, Mutant/RNAi screening, Oxidative Stress, Neurodegeneration, Developmental toxicology, Ecotoxicity experiments and more.


Based on an innovative system of 384 IR microbeams, the system detects the small interferences generated by the organisms present in the sample. In this way, a pattern of activity is recorded and processed using software specifically designed for real-time data acquisition. The digital analysis of signal changes (proportional to light intensity) allows us to detect the movement of the organism as it passes through the beam of light. An algorithmic software calculates the number of activity events per unit time.

With WMicrotracker-ONE, You Can Obtain Fast And Accurate Measurements Of The Movement Of C. elegans On Multi-well Plates.

Obtaining results is very straightforward. The data is robust, reproducible, and free from user bias. A long kinetic recording can be performed entirely automatically.

Experiments based on measurements of behavior and viability. Mainly designed for liquid culture medium and multi-well plates of 96 and 384 wells. Flexible animal models: 0.1-10 mm. which have swimming movements.

For any early stage or experienced laboratory. With affordable price for small laboratories. Focused on a varied field of experimentation. Intended for the academic and research sector, university teaching and for companies.

The system detects the movement of organisms through the interference caused by them in an array of micro beams of infrared light. (Patented Technology # US12515723, EP208640881).
