STP 420ES Rotational Tissue Processor

As the leader in the innovation of stains, reagents, and instrumentation, the next generation of the tissue processor has been created– Thermo Scientific STP 420ES. This truly revolutionary instrument can accommodate overnight processing, same-day processing, or just about anything in between—with this dual chamber processor, the choice is really yours.

Performance

• STP 420ES tissue processor features continuous movement of up to 360 cassettes within the main processing chamber
• Rotational agitation, long used in other industries, provides a more efficient, dynamic means of tissue-fluid exchange and interaction
• Recent studies conducted with a major Midwest university show fluid exchange ratio of the rotational agitation to be seven times more effective in processing tissue than conventional tidal agitation
• To accommodate traditional tidal action, unit also has a 60-cassette processing chamber
• Secondary chamber can be operated in conjunction with, or independent of, main chamber
• Unit is completely enclosed and incorporates self-ventilation via a water tank and charcoal
• Optional use of the Remote-fill-and-drain system minimizes reagent exposure risks, simplifies reagent changeover, and can be used during runs
