Proper Sterilisation Method

Proper Sterilisation Method main image Proper Sterilisation Method image


Prior to sterilising, inspect all instruments for cleanliness. Ensure that instruments are visibly clean and free from stains and debris, INCLUDING any detergent residue - as this can cause staining upon autoclaving. If an instrument exhibits staining please refer to our Stain Indication Guide on page 54 of our catalogue.

To sterilise instruments follow these steps:

1. Lubricate
Any hinged instruments should be inspected for adequate lubrication at the screw or box joint. Treat any instruments lacking adequate lubrication. A non-silicone, water soluble lubricant must be used. We recommend using our Premixslip Instrument lubricant & Rust Inhibitor (CHE345PMX5) DO NOT use industrial oils or lubricants.

2. Autoclave Sterilisation
Instruments may be sterilised either individually or in sets.
i/ Individual Instruments: Disposable pouches are ideal. Make sure to use a pouch that is wide enough for instruments with a ratchet lock so the instrument can be sterilised in an open (unlocked) position. Instruments that are locked during autoclaving can experience cracking around hinges or other problems due to heat expansion.
ii/ Instrument Sets: Unlock all instruments and sterilise in open position. Place heavy instruments on the bottom of set (when two layers are required). DO NOT OVERLOAD trays or chamber.

CAUTION: With most portable tabletop autoclaves, at the end of the autoclave cycle and before the drying cycle, unlock the door and open slightly (about 5mm). Then run the dry cycle for the period recommended by the autoclave manufacturer. If the autoclave door is fully opened before the drying cycle, cold air will rush into the chamber causing condensation on the instruments that may result in water stains or cause wetpacks. Check autoclave filters and chamber cleanliness regularly. Tip; Instrument Stain Remover is an effective way of cleaning the autoclave chamber.


2. Chemical/Cold Sterilisation
Most chemical/cold sterilisation treatments render instruments sterile only after 10 hour immersion. This prolonged action can be more detrimental than the usual 20 minute autoclave cycle. Follow sterilisation cycle and process as recommended by the steriliser manufacturer.

CAUTION: For instruments with tungsten carbide insert jaws, we do not recommend using chemical/cold sterilisation treatments as the action may deteriorate the tungsten carbide.
