Before function check

• All instruments (new or repaired) should be removed from original packaging and processed before being returned to a tray or stored to use later.  For new instruments this builds up the passivation layer to prevent corrosion.
• Visual check on cleanliness ie. free from blood, organic and protein residues as well as other contamination. It is advisable to work with lights and magnifying glass.
• If there are any residues, another manual reprocessing is necessary.
• Assemble the instruments prior to the function check.
• Maintenance / lubrication needs to be undertaken before function testing.

During function check

• Function tests are to be carried out carefully. The instruments which no longer comply with their intended use, e.g. by damage or abrasion, are eliminated accordingly.
• Check in particular serrations, joints, all lumina and tube shafts for consistency.
• Instruments with moving parts must be lubricated with suitable maintenance oil to prolong life.
• Lubricate with Sterilit® oil spray all jointed instruments to prevent friction corosion. Open and close instruments several times, this will ensure that the lubrication will be placed correctly before sterilisation. 
• During the cleaning process, it is recommended to use chemicals which have been tested and approved by chemical manufacturer and meet standard guidelines.
• Avoid contact with chlorides. Saline near instruments causes corrosion.

After function check

• After reprocessing, please cool down the instruments to room temperature. Otherwise there is a risk of material abrasion.
• Damaged instruments need to be removed and returned back to the manufacturer for repair.
• If in doubt, contact manufacturer for suitable test methods.
