The purpose of the present paper is to describe the effect of our vetrical laminar air flow unit for aseptic operation. Our unit has the ability to remove approximately 99.97% of all particles larger than 0.3 microns in diameter from air.
The degree of cleanness in the room can be achieved the class 100 classfication within few minutes after settinig the unit. Air contamination was tested by exposing three brain-heart infusion agar culture plates on the operating table during the course of the operation. The result has been estimated as averaging zero to two colonies per plate during 15 minutes on each stage of the procedure.
