The AUTION HYBRID™ AU-4050 analyzer is no longer available. ARKRAY is committed to delivering the best customer care and will continue to provide the supplies and support required for the operation of the current AUTION HYBRID™ AU-4050 analyzers through December 31, 2022.

Optimize workflow with true walkaway automated urinalysis

Maximize your laboratory performance with the AUTION HYBRID AU-4050; a compact fully-automated and integrated urine analyzer that combines two proven technologies to perform urine chemistry and sediment analysis. The easy to use analyzer reduces operator variability, while optimizing laboratory workflow in one small package.

Quality Results

The AUTION HYBRID AU-4050 uses two industry trusted technologies to perform urine chemistry and sediment analysis. The chemistry analysis uses the proven AUTION dry pad urine chemistry strips. Sediment analysis is performed by florescent flow cytometry in two separate chambers to reduce subjective interpretations using stains to accurately identify and enumerate key formed elements. The combination of urine chemistry and sediment technology generates standardized and accurate results on one consolidated report, providing operator confidence time after time.


The AUTION HYBRID AU-4050 provides everything into one small package.

Compact Size

The hybrid analyzer consolidates urinalysis testing into one compact platform, making fully automated urinalysis a reality for laboratories of most sizes and volumes. The space saving design is 30-50 percent smaller than competitive products and is an ideal fit to meet laboratories space constraints. It accommodates almost any existing space with little to no remodeling required.

Optimize Workflow

The high capacity system can meet the busiest laboratory workload demands processing up to 200 chemistry samples an hour and delivers rapid results in as little as two minutes and fifteen seconds. The easy to use walkaway analyzer provides operators the freedom to multitask. Operation is simple, load specimens, walk away to perform other activities, and return to the results. Reduce manual hands on time focusing only on results flagged for review.
