Evidence Investigator

Versatile, efficient and comprehensive testing

The Evidence Investigator is a compact, semi-automated benchtop platform which avails of the world's most comprehensive toxicology test menu. Utilising revolutionary Biochip Array Technology, this analyser facilitates simultaneous detection of multiple drug metabolites from a single sample. With the ability to consolidate a number of immunoassay tests, the Evidence Investigator is an efficient and cost effective solution for drugs of abuse testing, providing laboratories with a highly sensitive immunoassay screen.

Features & Benefits

Simultaneous Analyte Detection

The multiplex testing capabilities of Biochip Array Technology facilitates simultaneous screening of various drug metabolites across six toxicology arrays on the Evidence Investigator.

Extensive Test Menu

With more novel and routine drugs tests available than any other sole supplier, the Evidence Investigator utilises the world's largest toxicology test menu.

Small Sample Volume

When using the Evidence Investigator, only a small sample volume of 7-25 µl is required, leaving more sample remaining for confirmatory testing.

Multiple Matrices

The Evidence Investigator facilitates highly sensitive immunoassay screening of multiple matrices including serum, plasma, whole blood, oral fluid, urine and forensic matrices.

Accurate Testing

Multiplex analysis minimses analytical variation between tests and has a proven high standard of accurate tests results with CVs typically <10% with a reduction in false positives.

Optimum Efficiency

Multi-analyte controls and calibrators and multiplex testing capabilities facilitate laboratory efficiency and deliver a cost consolidating solution for the toxicology laboratory.
