Capitainer® B Vanadate – Optimized Microsampling for PEth Alcohol Testing

The Capitainer® B Vanadate device enables the precise collection of 10 µL whole blood onto a filter paper card, preloaded with sodium metavanadate to stabilize phosphatidylethanol (PEth). PEth is a sensitive biomarker for alcohol consumption, and this device supports both clinical and forensic testing workflows with consistent, user-independent sample quality.

Key Features:

• Accurate volumetric blood collection (10 µL)

• Dried blood spot sampling with built-in vanadate stabilization

• Supports long-term sample integrity for PEth quantification

• Self-sampling device with no user training required

• CE-marked for professional use

Benefits:

• Stabilizes PEth directly on collection

• Enables ambient storage and shipping

• Ideal for clinical, forensic, and remote collection scenarios

• Reduces variability due to hematocrit or sampling error

• Compatible with standard PEth extraction and LC-MS workflows

Applications:

• PEth testing for alcohol consumption

• Forensic toxicology

• Workplace or rehab screening

• Public health surveillance

• Clinical research

With Capitainer B Vanadate, PEth testing becomes scalable, accurate, and logistically efficient — without the need for venous draws or lab-based collection.
