Microm STP 120 Spin Tissue Processor from Thermo Scientific

Thermo Scientific STP 120 Spin Tissue Processor is a compact, benchtop carousel tissue processor. Designed to process biological specimens from chemical fixation to paraffin infiltration. Unique design uses programmable gentle centrifugal force to augment normal vertical agitation process associated with carousel processors.


  • Immediate and delayed start processing modes
  • Programmable spinning speed of either 60 or 70rpm; spinning can also be programmed off
  • Programmable immersion time in each station (from 1 minute to 99 hours: 59 minutes)
  • Basket capacity of 120 or 240 cassettes
  • Battery backup system in case of power failure


  • Reagent vessel tops and charcoal-enhanced ventilation help control processing vapors
  • Maintains up to 10 different processing programs
  • Cassette baskets spin counterclockwise and clockwise within reagent container to improve processing
  • Reagent carryover is reduced through gentle centrifugal spinning of basket above reagent vessel
  • Each reagent vessel holds 1.8L of processing reagent
