Concerning Sterilization Items Warning

Porous caps

• Do not place the sterilization items inside containers or bags which will not allow steam to pass through. 1 Do not use stoppers to seal up containers which have sterilization items inside. Either use porous caps or loosen the lids sufficiently. 1 Do not allow the sterilization items to block the holes or temperature sensor inside the chamber.

Sterilizing and melting cultures and other liquids • Capacity of culture to capacity of container Pour in the liquid while taking care not to exceed the container's rated amount. Quantities exceeding the rated amount may boil over. • When sterilizing large quantities of cultures, etc. The time when the whole culture reaches the sterilizing temperature is reached after a delay time subsequent to the time when the temperature inside the chamber has reached the sterilizing temperature. Refer to the table below, and add the sterilizing time and delay time to arrive at the sterilizing setting time which is to be used.

Time

•^ When the culture is to be sterilized in a small quantity, the temperature inside the chamber rises more quickly and the delay time is increased.

- What we recommend: An "Object temperature sensor" which detects the temperature of the sterilization items and controls the sterilization timer is available as an optional accessory. Even after this sensor has been installed, control can still be switched over to the unit's sensor by pressing the OBJECT TEMP, button ON and back by pressing it OFF. Use the optional sensor to make the sterilization even more dependable. For details, contact your dealer.

Plastic container

> When using plastic containers for sterilization Increase the sterilizing setting time even more. Otherwise, incomplete sterilization may result since these containers are poor conductors of heat. • When melting general agar media in solid form Refer to the table below, and set the melting time (per flask).

Concerning Sterilization Items Sterilizing equipment, etc. Warning When sterilizing only containers such as beakers, flasks or test tubes, place them on their sides or upside down with their openings at the bottom. Placing the containers right side up with their openings at the top will make it hard for the air inside to escape and for the steam to penetrate sufficiently inside, and incomplete sterilization may result.

Sterilizing as part of waste material processing Warning When sterilizing items in a sterilization bag, pour about 300 milliliters of water inside and keep the bag open. Failure to pour water inside the bag or sterilizing items in a bag whose opening has been closed may cause incomplete sterilization.

Checking the sterilization performance Warning Check the sterilization performance. This performance varies depending on such factors as the volume and types of sterilization items, the way the items are loaded into the unit and the types of containers used. Be absolutely sure, therefore, to check the sterilization effects using a sterilization indicator such as an "OK card." Such an indicator is an effective way of preventing incomplete sterilization and accidents.

Sterilizing items in containers with a large capacity (10 liters or more) and very small opening - Advisory note When placing a liquid inside a container with a large capacity (10 liters or more) and a very small opening for sterilization, fill the container to at least 50% of its capacity. When a small amount of liquid in such a container is sterilized, the pressure during sterilization will increase, and steam may be discharged from the pressure safety valve. To sterilize a small amount, either use a container with a large capacity and a wide opening or replace with a small-capacity container suitable for the quantity of the liquid. The water in the exhaust tank increases with each sterilizing operation. When it has risen to the HIGH (maximum) level mark, dispose of the water and fill the tank with fresh water as far as the LOW level mark.
