What It Is

CycleCheck® is a “Every Cycle Test for Instrument Washers” that records the thermal disinfection temperature reached during a washer cycle and indicates whether water reached the surface of the coupon during the cycle [1].

When To Use It

Use CycleCheck® for each cycle of an automated instrument washer to verify that the washer achieved the required thermal disinfection temperature (either 82 °C or 93 °C) and that water contacted the test surface [1].

Use Matrix

Target temperature Indicator change required Water indicator required Interpretation
82 °C (180 °F) 82 °C circle turns black Hydrophilic circle turns yellow Pass if both changes occur; otherwise temperature fail
93 °C (199 °F) 93 °C circle turns black Hydrophilic circle turns yellow Pass if both changes occur; otherwise temperature fail
No water contact Any temperature circles may change, but hydrophilic circle remains black Black Complete failure – water did not reach indicator
Temperature not reached Hydrophilic circle turns yellow but both temperature circles remain white Yellow Water reached indicator but temperature thresholds not met – temperature fail

How To Use It

  1. Peel the CycleCheck® indicator from its release paper and adhere it to the TOSI® rack on a dry, clean surface (Fig. 1) [1].
  2. Place the TOSI® rack on the bottom of a surgical tray; load instruments on top of the rack (Fig. 2) and position the tray on the middle shelf of the washer rack (Fig. 3) [1].
  3. Run the selected washer cycle. During the cycle the temperature indicator circles will change from white to black when their respective thresholds (82 °C or 93 °C) are reached, and the hydrophilic water indicator will change from black to yellow when water contacts the surface [1].
  4. After the cycle, allow the tray to cool, then remove the TOSI® rack and document the results (both temperature and water presence) in the approved log sheet or electronic system [1].

Common Questions

Question Answer Source
What does CycleCheck® indicate? It records the thermal disinfection temperature reached during a washer cycle and shows whether water reached the surface of the coupon. [1]
How many temperature thresholds does CycleCheck® monitor? Two thresholds: 82 °C (180 °F) and 93 °C (199 °F). [1]
How is water presence shown? The hydrophilic indicator changes from black to yellow when water contacts the indicator. [1]
How many units are in a typical purchase package? A case contains twenty‑four CycleCheck® indicators. [2]
