the bags do not contact with the inner wall of the sterilizer. Sealed bags will result in inefficient sterilization. If the
sterilization chamber is over crowded, steam can not reach every corner, will result in incomplete sterilization.
〇 When sterilizing the glassware like beaker, conical flask and test tube, the vessel must be put up side down or across.
If the vessel can only be in vertical direction, put a little water in the vessel before sterilizing.
〇When sterilizing the liquids like chemical reagent or menstruum, care must be taken to the volume of liquid inside the
container (3/4 of total volume of flask, and 1/2 of total volume of test tube), so that the liquid will not overflow from the
container during sterilizing.
〇 The cover of container to be sterilized should be loosened for air exhaust to prevent container broken.
〇 When melting the agar, each container should be less than 2 L, otherwise the melting may not be completed
thoroughly.
〇 The DURHAM TEST TUBE with over 6mm caliber should be used, otherwise air bubble may stay in the tube.
〇 Please put article temperature sensor properly if the instrument is attached artilcle thermometer.
5.Closing the sterilizer chamber cover
1) Push the handle leftward slightly until the arm leans against the arm stopped.
2) Turn the handle until it is secured and the cover closed indicator " Locked" is on. The cover closed indicator may
change repeatedly in course of tightening. When it is nearly secured, turn the handle slowly while observing
whether the cover closed indicator is on or not.
6. Selecting sterilizing program
Select the sterilization mode, set up the Sterilization time and drying time according to your needs.

★Note:
〇 For sterilization of liquids, set a sterilization time longer than desired, taking a delaytime
into account:For example, if the volume of water in the flask is 3L , when the internal
temperature of the sterilizer chamber reaches the set value, another 33 minutes shall be
required for the water in the flask to reach this temperature, therefore, the sterilizing time
must be set to 53 minutes.
