Programmable auto-start operation

 

  Common to all modes   

                                                                                (when the programmable auto-start operation is used)   

   

The remaining time in the reservation timer is shown on the digital display. 

Air release stage 

……

  Liquid mode, agar mode, and solid mode 

   

The illuminated air release section on the stage display changes to blinking, and the 

        temperature and pressure inside the chamber begin to be shown on the digital display. 

   

Air releasing will continue until the preset air release time passes after the temperature inside 

        the chamber reaches 97

 

Heating stage

 

……

Liquid mode, agar mode, and solid mode 

   

The illuminated heating section of the stage display changes to blinking. 

   

Temperate continues to rise until the exhaust valve closes and the temperature (pressure) 

        reaches the preset sterilization temperature (pressure). 

 

Heating stage

 

……

  Dissolution mode 

   

The illuminated air release section on the stage display changes to blinking, and the 

        temperature and pressure inside the chamber begin to be shown on the digital display. 

   

The temperature continues to rise until it reaches the preset dissolution temperature. 

 

Sterilization stage 

……

  Liquid mode, agar mode, and solid mode 

   

The sterilization section of the stage display changes to blinking from steady state, and the   

        sterilization set time appears on the digital display simultaneously with start-up of the 

        sterilization timer. 

   

The temperature (pressure) is kept constant during the preset sterilization time. 

   

When the temperature inside the chamber decreases by "0.1

" or more from the set value 

        because of an error, the overcool mark on the digital display lights up, and the sterilization 

        timer stops operation. Operation is resumed when the temperature reaches the setup 

        temperature again. 

 

 

 

The digital timer shows the remaining time during the sterilization stage. Press the "SET"   

        switch to confirm the preset time. While the switch is being pressed, the set value is displayed. 

        The set value cannot be changed. 

 

 
● 

In sterilization of petri dishes or empty containers, the air remaining in the container expands and 

      may increase the pressure extraordinarily within the chamber. If the pressure in the chamber 
      exceeds the saturated steam pressure, the automatic exhaust valve opens and discharges the 

air in the chamber into the drain bottle. 

● 

The chamber temperature is kept slightly higher so that it will not drop below the sterilization set 
temperature.

 

 

Dissolution stage

 

……

  Dissolution mode 

 

   

The illuminated dissolution section of the stage display changes to blinking, and the dissolution 

        set time appears on the digital display simultaneously with actuation of the dissolution timer. 

   

The digital timer shows the remaining time during the dissolution stage. Press the "SET" switch 

        to confirm the preset time. While the switch is being pressed, the set value is displayed.     

        The set value cannot be changed.
