Bio contamination |
Can cause rust on the device due to hand sweating, chloride atmosphere and tap water, Bacteria, Ammonia gas |
Avoid the atmosphere of ammonia gas, chloride ions, tap water.Use gloves during operation to avoid hand sweating having the particles ofHydrogenSulfide
|
Check the instruments with the help of boil test. Apply some force |
No rust No indication of stress corrosion cracking. |

Bio incompatibility |
Color change and black deposits appear due to clotting of blood on the device.Some bacteria and chemicals also produce different color. Tap water has also effect for producing fade color and affecting the life. |
Do not put the devices in blood during operation. Always clean with distilled water after operation. Avoid the instruments from dust and other contamination. Properly preserve the instruments.
|
Check that there is no deposits of any color due to dust or contamination. |
No depositsNo rust |

Toxicity |
Depletion of Chromium layer can cause toxicity stainless steel is corrosion resistant because it has chromium oxide layer that prevents it from rust and corrosion and if the solution of high pH is used then this solution or detergent strengthens on the surface of the instrument and during sterilization in the autoclave the detergents or solution strengthens by the effect of heat and also removes chromium oxide layer and as a result of the removal of chromium oxide layer, corrosion occurs. |
pH of the solution and detergents must be maintained in between the range of 6.0 to 8.0. |
Proper techniques of Autoclaving and Sterilization |
No rust |
