The Thermo Scientific* Cytospin 4 Cytocentrifuge is the ultimate thin-layer cell preparation system.

Synonymous with cytocentrifugation for over 40 years, this reliable instrument is used in more than 15,000 laboratories worldwide. It provides economical thin-layer preparations from any liquid matrix, especially hypocellular fluids such as spinal fluids and urines.



  • Processes 12 specimens at one time
  • Accepts all protocols from Cytospin 1, 2, and 3
  • Redesigned lid-release mechanism allows for one handed opening and closing
  • Only operates when the lid is locked into position and lid remains locked during rotation
  • Polycarbonate window allows the operator to see the sealed head during cytocentrifugation 
  • Accidental fluid spillage will not damage the mechanical or electronic components
  • Designed for easy disinfection
  • Meets stringent IEC 61010 standards for centrifuge safety
  • Pull-out program card allows for up to nine programs to be logged for fast and convenient retrieval
  • Safe and Reliable
  • Protects the operator before, during, and after sample preparation
  • Ultimate safety procedures allow loading of the sealed head in a microbiological cabinet
  • Auto-locking, plastic outer lid
  • Disposable sample chambers with caps
  • Safety alarms protect users and specimens
  • Wipe-clean control panel
  • Simple Principle for Excellent Presentation
  • Using centrifugal principles, the cytocentrifuge deposits cells onto a clearly defined area of a glass slide and allows for the absorption of the residual fluid into the sample chamber’s filter card
  • Cytocentrifugation also constructively flattens cells for excellent nuclear presentation  
  • During operation, the instrument’s spinning action tilts the Shandon* Cytofunnels* upright and centrifuges cells onto the deposition area of the slide, giving all cell types equal opportunity for presentation
  • In the Load or Stop position, this unique tilting feature reduces cell loss by preventing residual fluid from coming into contact with the prepared slide
  • Simple and Precise Controls
  • Protected program memory stores up to 23 routines for instant recall and protects from power loss
  • Program keypad has “easy-touch” design that allows for easier keystrokes and more intuitive programming
  • Speed window displays the programmed spinning speeds from 200–2000rpm
  • Time window displays the programmed and remaining run time from 1 to 99
  • Control feature has a standby power-saving mode; displays are also turned on and off by the standby key
  • Safety alarms include an audible alarm when the cytocentrifuge is out of balance, outside the speed tolerance, or if the lid is not properly locked
  • Unit will not spin if the lid is not locked
  • Specimen safety alarm feature reminds users at one minute intervals to remove specimens, protect them from air-drying, and ensure consistent results
