ESS series
The ESTERI standard model embodies "quick," "easy," and "certain."
The ESS series was developed in response to ESTERI's slogan, "We want to do this more."
Designed for quality control, research facilities, and educational institutions, this system strives for simplicity and efficiency, providing value that not only meets but also exceeds the sterilization needs of laboratories.
With a heater and cooling fan that are maximized within the limited power environment, we have achieved a 30% reduction in heating and cooling time compared to conventional models.
Additionally, data storage (optional) allows you to view and store driving data such as settings and temperature/time/error history on your PC, making daily sterilization easy.
The ESS series enables a lean and highly efficient research environment.
Other options
-
Product temperature sensor :
It can measure the temperature of the sterilizer center and can also be used as a sterilization timer start. -
Printer:
You can print driving data onto thermal paper. -
Highland specifications:
It cannot be used according to standard specifications in areas above 1000m above sea level.
The specifications need to be changed to match the altitude.
Data storage function (optional)
Poor sterilization has a significant impact on subsequent inspections and evaluations.
To prevent this, BI (biological indicator) and CI (chemical indicator) are used to check whether sterilization is possible, but the increased costs associated with these are unavoidable.
The data storage function makes daily management easy by reviewing and storing daily driving data on the PC, reducing running costs such as BI and CI.
Furthermore, by using it in conjunction with a product temperature sensor (optional), the central temperature of the sterilized items (the area that is most likely to be sterilized) can be measured, and the required sterilization time can be determined numerically, making it effective for reliably calculating sterilization conditions.

1. Sterilization
This is a sterilization-only pattern. It is commonly used in liquids, appliances, etc.
● Heating →sterilization→ Cooling
The shortest possible processing time is achieved through a simple process.
For sterilizing instruments and other equipment, the pressure can be rapidly reduced by automatically evacuating the equipment after sterilization using the "EXHAUST" setting, further shortening the cooling process.
2. Sterilization - Keep warm
The sterilized liquid culture medium can be stored at room temperature without solidifying.
● Heating →sterilization→ Cooling →keep warm (40～60℃)
Keeping the medium warm at 40 ～60℃ after sterilization prevents it from solidifying, allowing for efficient operation without interruption of subsequent dispensing.
3. Dissolution - Keep warm
It is primarily used to dissolve sterile, jelly-like culture media.
● Heating → Melting (40～99℃) → Cooling → Keeping warm
Dissolution can be set in a temperature range of 40 ～99℃, so it can also be used for simple boiling disinfection and pasteurization.
Furthermore, by pre-running this process using a calendar timer and keeping the equipment warm, the subsequent sterilization operation time can be further reduced.
Footer interlock function
It locks securely with the simple operation of tightening the foot and sliding the lever.
A secure design that will not activate if the slide is insufficient, causing an alarm to sound. It stays securely in place while driving and prevents burns by not releasing the lock until the temperature drops.
Air-burning prevention function
If there is a water shortage, an alarm will sound and the system will automatically shut off. Prevents equipment from burning dry and damaging sterilized items.
Temperature over-rising/over-pressure prevention device
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
An alarm will sound or stop the vehicle from operating if the temperature sensor fails.
Instruments crucial for temperature control prevent equipment from running out of control.
Ground fault breaker
Senses a power leakage in the equipment and turns off the main power supply. It activates in the event of a water leak or electrical component failure, preventing electric shock to the user.
Pressure safety valve
It allows steam to escape from the can when the pressure rises to an abnormal level, preventing the pressure from rising. This is a dual safety device that activates in the unlikely event that an electrical safety device malfunctions and the equipment goes out of control.
Data Storage
This is a management system that allows you to import data into your PC via USB memory connection. Under standard conditions (121℃, 20 minutes, 10 seconds sampling cycle), approximately 1000 cycles of data can be stored.

Product temperature sensor
Product temperature mode operation
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.
printer
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.

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.
Metal basket
Do not place sterile materials directly into the can body. This not only leads to malfunctions but also serious accidents. Be sure to insert a wire mesh basket containing sterile materials.
The ESS series comes standard with the following wire mesh baskets: To sterilize liquids, place the container in a wire mesh basket or purchase a separate sterile container (accessory).

Kago bottom storage dish
Sterilizing waste materials such as used petri dishes can contaminate equipment by spilling molten liquid.
To prevent equipment failure due to this, it can be stored in the bottom of a wire mesh basket to receive any spilled liquid.

Sterile container
Use sterile containers to sterilize large quantities of liquids, viscous substances, or soil.
However, unlike wire mesh baskets, when used in layers, they trap air in the lower container, resulting in poor sterilization.
Always use only one.
