Testing Surgical Instruments for Corrosion Resistance
Any surgical instruments you purchase in the UK, which are CE marked should be correctly passivated and corrosion resistant. You can carry out a simple test which is recommended in the British standards for Surgical Instrumentation (BS 5194 series), to detect any free iron and chromium depletion.
What you need:
1. Copper sulphate solution
2. Distilled water
The instrument is manually cleaned the and immersed in ethanol, then dried. Instrument is dipped in the copper sulphate solution for 6 minutes at room temperature, removed, washed with distilled water and wiped. You can then check for copper deposits, which if significant will show up as pink marks, where potential areas for corrosion are detected.
This can also be used to detect non surgical instruments which are being used on trays in correctly, please see the following stationary bulldog clip:
