The STF Load Check indicator and holder are intended for use inside each basket or tray to verify the cleaning efficacy of a surgical instrument washer-disinfector machine.

The dried test soil formula, printed on both sides of the indicator ,contains two sources of protein, lipids and polysaccharides and is formulated to mimic the cleaning efficacy soil tests for surgical instruments described in BS2745, EN/ISO15883 and UK Guidance Document HTM2030.

Simply place an STF Load Check indicator in the holder, and place the device (indicator and holder) in the tray or basket.  After running one complete cycle, remove the STF Load Check indicator from the holder and examine for evidence of residual soil.

Complete removal of the dried ‘test soil’ pattern from the plastic substrate provides a qualitative assessment of the washer-disinfector cleaning performance.
