Get the superb tissue quality and proven reliability you expect, plus a safer, more efficient working environment, with the Thermo Scientific™ Excelsior™ AS Tissue Processor which provides exceptional and enhanced tissue quality with minimal user interaction. To help ensure consistent high quality service and results, use Thermo Scientific™ reagents and paraffin. 

Enhanced tissue quality
  • Cassette baskets are gently rotated inside the circular chamber, providing more effective agitation than an impeller
  • Reagents can be pre-heated to up to 35°C, minimizing tissue shock and facilitating reagent penetration
Significant reagent cost savings
  • Alcohol quality measurement enables you to extend your reagent life and provides significant cost savings
  • Automatic reagent rotation further extends reagent life using a proven system
Streamline workflow and increase productivity
  • Reduce maintenance time by replacing one bottle of each reagent, rather than all of them
  • Draw new reagents directly into the processor from your supplier’s bottles—no pouring, no mess, and no fumes
  • Run rapid biopsies during the day and conventional programs overnight
  • Compatible with IPA xylene-free processes as well as conventional reagents
Safe for the tissuesafe for the operator
  • When the chamber is opened, a fan pulls fumes through a filter to protect users from formaldehyde exposure
  • Fumes from the cabinet are also extracted through filters to protect users from alcohol, xylene, and formaldehyde
  • Waste paraffin can be removed by simply discarding a plastic tray—no paraffin spillage and burns
  • Power outages are no longer a concern; Excelsior keeps your tissue safe with battery backup
So simple to learn and operate
  • The all-new touch-screen interface is intuitive and easy-to-learn
  • With intelligent software, it’s easier to avoid mistakes that affect tissue quality
Engineered for reliability and peace of mind
  • The Excelsior AS Tissue Processor reflects engineering enhancements based on more than 10 years of service history
Infomatics to integrate the laboratory and simplify reporting

  • Reports are easily downloaded via a USB drive
  • Messages can be sent automatically to the laboratory information system
  • Remote alarms ensure that any problems are immediately addressed
  • Thermo Scientific™ NetMon™ II monitoring system allows remote diagnostics over a HIPPA compliant, secure internet connection for immediate identification and resolution
