True continuous-access automated IHC/ISH slide staining
for unprecedented workflow efficiency

Maximize Capacity

Individual slide drawers enable single piece flow to limit wasted slide positions.

Optimize Efficiency

Continuous access to each slide and protocol flexibility without sacrificing stain optimization.

Improve Processing Time

Decreased preparation time required for slide sorting and matching of reagent.

Quickly Respond to Test Requests

Ultimate Reagent Access (URA) allows immediate processing of urgent and late-arriving samples.

Increase Workflow Flexibility

During a run, users have continuous access to bulks and waste.


BenchMark ULTRA system

Unprecedented workflow

IHC, ISH, SISH, Dual Stain and FITC slides can be processed simultaneously, improving turnaround times. The fully automated workflow enables processing of 90 slides in 8 hours, or 120 slides with an overnight run.

Real-time remote monitoring and technical assistance

The BenchMark ULTRA system is equipped with CareGiver remote monitoring technology, offering 24/7 online support for basic troubleshooting and technical guidance. This provides proactive instrument service and maintenance, helping expedite recovery times to minimize system downtime.
