EFN Series
High sterilization performance is guaranteed by reliable degassing controlled by temperature and pressure.
The EFN is an upper-middle-class model that offers a good balance of operability, sterilization performance, and safety.
It is suitable for routine sterilization work in the pharmaceutical industry and research institutions, and can be used in a wide range of applications, for example to sterilize liquid media, used petri dishes, and tubes (with an inner diameter of 10 mm or more).
By optimizing heating conditions and improving cooling efficiency, we achieved a reduction in processing time compared to conventional machines.
A variety of additional options
- Printer (heat-sensitive)
- Product temperature sensor
- Data logging system
- High-altitude compatible settings

1. Liquid “open”
It is suitable for sterilizing liquids in containers such as flasks, beakers, and vial bottles.
The purpose is to prepare sterile water, sterilize or sterilize liquid media such as LB medium, NB medium, TSB medium, BHI medium, and EC broth, buffer solutions, physiological saline, and other liquid samples, and keep them warm.
2. Liquid “sealed”
It is suitable for sterilizing liquids in containers such as flasks, beakers, and vial bottles, which are capped with cotton or sponge stoppers.
The purpose is to prepare sterile water, sterilize or sterilize liquid media such as LB medium, NB medium, TSB medium, BHI medium, and EC broth, buffer solutions, physiological saline, and other liquid samples, and then keep them warm.
3. Instruments
Suitable for sterilizing heat-resistant instruments, etc.
It is intended to sterilize glassware such as test tubes/beakers/flasks, porcelain such as mortars/pestles/evaporation dishes, metalware such as tweezers/scissors/spatulas/wire loops, rubber such as silicone tubes/O-rings, plastics such as bottle-top filters, paper or textiles.
4. waste
It is suitable for sterilizing waste contaminated with microorganisms, cells, etc.
This product is intended for sterilizing mixed products such as used culture media, cleaning wastewater, pipette tips, petri dishes, and paper towels and wipes used for blotting, placed in sterile disposal bags or stainless steel containers.
5. Dissolution
Suitable for killing common bacteria at 75 ～85℃.
The purpose is to treat at 100℃ or less, and to keep sterilized powder culture media warm to prevent coagulation.
Furthermore, by pre-running this process using a calendar timer and keeping the equipment warm, the subsequent sterilization operation time can be further reduced.
Futa Interlock System - Futa Open/Close Detection
It features a sliding lever one-touch lock, ensuring both operability and safety.
If the footer is not securely locked, you will not be able to start driving.
It also features a double-locking mechanism that cannot be unlocked until the temperature and pressure are reduced.
Anti-firing function
If there is a water shortage, an alarm will sound and the system will automatically shut off.
This prevents overheating due to dry lighting and ensures the safety of the equipment and its users.
Ground fault breaker
Senses a power leakage in the equipment and turns off the main power supply.
It activates in the event of a leak or electrical component failure, and
It prevents electric shock.
Temperature and pressure prevention function
An alarm will sound and heating will stop if the can temperature exceeds the set temperature and pressure while driving.
This can easily occur if too much sterile material is packed into the container.
Sensor break detection
An alarm will sound and stop operation if the temperature sensor fails.
Instruments crucial for temperature control prevent equipment from running out of control.
Pressure safety valve
It prevents the pressure from rising by allowing steam from inside the can to escape when the pressure rises to an abnormal level. This is a dual safety device that activates in the unlikely event that the electrical safety device malfunctions and the equipment goes out of control.
Product temperature sensor
The core temperature of the sterilized material rises later than the temperature of the can body. For example, 1 liter of liquid needs to reach 121℃ 10 minutes after the device reaches 121℃.
By positioning the tip of the product temperature sensor at the center of the liquid, not only can the liquid temperature be monitored, but "product temperature mode operation" is also possible, in which the timer starts counting down when the liquid reaches the set temperature.
This ensures that multiple types of sterilization under different conditions can be performed.
Recording and management of driving data
Are you experiencing the hassle of using sterile data?
ENF connects a sterilizer to a PC and allows you to record the temperature, pressure, and time while the device is running in a dedicated application.
It can also be imported into Microsoft Excel®and quantitatively validates the data to support highly accurate sterilization operations.
Printer (heat-sensitive)
Automatic printing will begin as soon as operation starts, and the process will be recorded, including the timing of sterilization timer operation. By automatically completing the printing process at the end of operation, the sterilization process is visualized accurately and effortlessly, contributing to more efficient and reliable record management.

Recorders and temperature monitoring sensors (custom-made)
GMP requires reliable monitoring and recording of temperature during the sterilization process. This series allows for the addition of recorders and temperature sensors to constantly monitor and record the temperature and pressure inside the can.
This ensures reliable understanding of sterilization conditions and reliable data acquisition, contributing to improved traceability and a stronger quality assurance system.
High altitude support (altitude 1000m or more)
At high altitudes, a decrease in air pressure can lower the boiling point of water, which can affect the temperature and pressure control of the autoclave.
This series allows for setting changes depending on altitude conditions, ensuring proper sterilization conditions even in high-altitude environments and achieving stable operation.
Wire mesh basket
Do not place sterile materials directly into the can body. This not only causes malfunctions but also leads to serious accidents. Be sure to place the sterile material in the wire mesh basket.
This series comes standard with the following wire mesh baskets:
To sterilize liquids, place the container in a wire mesh basket or purchase a sterile container (accessory) sold separately.

Sterile container
When sterilizing large amounts of liquids, viscous substances, or soil,
Use a sterile container.
However, unlike wire mesh baskets, when used in layers, the bottom container
It traps air, resulting in poor sterilization.
Always use only one.
