132ºC Pressure Steam Sterilization Indicator Card 1982-0001

It is used to monitor the sterilization effect of fore vacuum or pulsation vacuum pressure steam sterilizer under 132ºC-136ºC, and downward displacement sterilizer (desktop or cassette type).

Place the chemical indicator card in the center of standard test package or where it is most difficult for the steam to permeate. Wrap the chemical indicator card with gauze or kraft paper to avoid dampness and ensure accuracy.

After a sterilization cycle, if the color of chemical indicator card turns black or dark grey from initial light blue, then the sterilization is done.

Keep it where ambient temperature is 15ºC~30ºC and relative humidity is 50%, and keep it away from corrosive gas.
