Review Methodology
How We Test & Rate Instruments
Transparent, rigorous, independent. Our 4-dimension evaluation protocol explained.
The Review Process
Instrument Acquisition
Manufacturer loan, direct purchase, or partner lab access. No paid placements accepted.
Controlled Testing
Standardized protocols with certified reference materials. Multiple operators to eliminate bias. Minimum 100 runs.
Data Analysis
Statistical analysis of performance metrics. Comparison against manufacturer specs and competing instruments in same class.
Write & Publish
Peer-reviewed by independent Scientific Advisory Board before publication. Raw data available upon request.
4-Dimension Rating System
Performance (40%)
Accuracy, precision, sensitivity, linearity, speed. Certified standards, controlled lab conditions.
Usability (25%)
Software interface, method setup time, training requirements, automation capabilities.
Maintenance (20%)
Consumable lifespan, preventive maintenance frequency, service contract costs, common failure points.
Value (15%)
5-year total cost of ownership vs. competitive alternatives. Performance-per-dollar ratio.
