Directions for use

Before sterilisation the instruments should be thoroughly cleaned with hot water and soap and carefully dried to prevent water from being added to the acetone.
The dry instruments are put in the box filled with 100% acetone and sterilised for a few minutes.
When the instruments are taken out it is recommended to shake them to make sure that all acetone is removed even from hidden corners, like screws, etc.

Sterilisation of hollow instruments with acetone is possible, but requires careful internal cleaning of the tubes and cannulas, first with air and then with saline, after sterilisation in order to prevent acetone from entering the eye inadvertently.
For safety sake hollow instruments probably can better the sterilisation by autoclaving.

To place the instruments on the surgical table, they can be simply removed by a forceps or artery clamp. Leaving the instruments a few minutes on the instrument table is a safe time to wait for full evaporation.

 

Note 1: Chalky deposits, caused by boiling with tap-water instead of with aqua destillata, can be removed by putting the instruments in vinegar for 30 minutes.

Note 2: After the surgery the instruments are carefully cleaned again with hot water and soap and after drying put back in the acetone sterilisation box.


Caution:
 

•	Never bring instruments immediately from the acetone to the eye!
•	Do not enter the acetone with ones own fingers, since this will bring greasy material and possibly some water into the acetone reducing its sterilising capacity.
•	Certain plastic materials may dissolve in acetone.
•	For transportation: Acetone can not be taken in an airplane. Danger code: IMCO 3.1 VN 1090.
