Autoclave

Overview

The HICLAVE HV-25Ⅱ from Hirayama is a high-performance lab autoclave that delivers consistent steam sterilization for laboratory instruments, culture media, and biological waste. Its advanced control system ensures accurate temperature and time management, making it suitable for daily laboratory sterilization and decontamination tasks.

Key applications include:

• Laboratory instrument sterilization

• Media and liquid sterilization

• Medical device disinfection

• Biological waste decontamination

A color touch panel that you can understand the operation at a glance is installed in the best-selling HV series autoclave. A one-touch lock mechanism, an interlock function that detects the pressure and temperature to lock the lid, and a number of functions such as the culture medium dissolution process are also installed as they are. We also offer various options.

• A forced cooling fan is an optional unit.

Features & Functions

• Color touch panel
• Electro-mechanical lid lock system
• Memory function
• Dual interlock mechanism
• Lid lock release temperature setting
• Air removal time setting
• Forced cooling unit(option)

 

Color touch panel
A color touch panel allows an operator to understand the operation screen contents at a glance.

 

Electro-mechanical lid lock system
The lid can be opened and closed easily and reliably with the one-touch lever. A pressure seal method is used as a safety measure.

 

Dual interlock mechanism
The lid is locked by dually detecting the chamber pressure and chamber temperature during operation. The lock state is maintained even if an operation is manually interrupted.

 

Memory function
Up to 8 patterns for each mode can be registered according to the purpose of use.

 

The lid lock release temperature setting
The lid lock release temperature can be set up for each mode or program to secure safety at the time of unloading. 

 

Air removal time setting
It is effective for sterilization of Durham tubes etc. from which air is difficult to escape. 

Dual detection system for residual air
The residual air which may cause sterilization failure is dually detected to always maintain the appropriate sterilization conditions for loads.

• Detection of residual air is performed dually when the chamber pressure is normal (during air removal by gravity displacement) and when the chamber is pressurized (during air removal by pressure exhaust).

 

Forced cooling unit (option)
After sterilization, the chamber pressure is lowered by cooling with a forced cooling unit (air-cool) to shorten the time to unloading.

 

Programmable auto-start function
It is a timer function that starts an operation at the set time.

• The operation start time can be set up to 1 week later.

 

Easy to Use with Color Touch Panel

A color touch panel allows an operator to understand the operation screen contents at a glance.

 

Confirmation items are notified at startup.	A mode can be selected simply by touching the screen.
When the power is turned on, the confirmation items before use are displayed. You can reduce the trouble by implementing the confirmation items.	A mode can be selected with the simple operation of tou- ching the desired mode from 5 modes displayed on the color touch panel and pressing the start button.

 

Color display makes it easier to understand various settings.
The settings of temperature, time, warming and exhaust can be easily changed by touch operation while checking the color screen.The set contents can be registered up to 8 patterns. It is very convenient when sharing and using with a plurality of names.

Security & Safety
Various information such as settings, safety and warnings are displayed on a color screen. More detailed contents are shown by text information.
[  Alarms  ] 11 kinds of alarms such as a low water heating alarm are displayed.	[  Alarm history  ] Alarm occurrence date, alarm contents and stage ID number are displayed.
[  System information  ] Progrm version number, cycle count, next self inspection date are displayed.

 

Operation Cycle of Each Mode

(Up to 8 patterns for each mode can be registered.)

LIQUID mode		Heating		Sterilization		Variable exhaust
Main applications: Sterilization of liquid, which can withstand high temperature and high pressure steam such as water, culture medium, reagent, reagent solution, liquid medicine, etc.
SOLID mode		Heating		Sterilization		Forced exhaust
Main applications: Sterilization of instruments made of glass, ceramic, metal or rubber that can withstand high temperature, high pressure steam and rapid pressure decrease during the exhaust stage.
WASTE mode		Heating		Sterilization		Forced exhaust
Main applications: Sterilization of waste using a sterilization bag and the like.
AGAR mode		Heating		Sterilization		Variable exhaust		Warming
Main applications: Sterilization of agar medium (It is warmed at constant temperature to prevent clotting after sterilization.)
DISSOLUTION mode		Heating		Warming
Main applications: Dissolution of agar medium (It is warmed at constant temperature to prevent clotting after heating.)

 Options for Upgrading a System (Retrofittable)

Forced cooling unit (air-cool)	Floating sensor	Recorder		Core temperature sensor
Used to shorten the time to unloading after sterilization	A sterilization timer operates after the temperature of the materials to be sterilzed reaches the set temperature.	(Image is a chart type recorder.) - Chart type recorder: 6-point dotting - Hybrid recorder: 8-point dotting Chart width: 100 mm Class 2 T-type thermocouple included		Class 2 T-type thermocouple Connection with recorder is required.

 

Printer	Automatic water supply unit
Thermal print type	Manual water supply to the chamber becomes unnecessary.

A large capacity and bucket-shape bottom can prevent the chamber from being contaminated when a sterilization bag is broken. [For HV-25II] φ210 x H420 mm [For HV-50II] φ270 x H600 mm Use a sterilization bag without closing the mouth.

 

Detergent for autoclave	Sterilization bag	Deodorizer
Detergent to remove culture media, water scale sticked to the inside of a chamber [Standard amount of use] 1 cap of detergent in 2 L of water (20 ml - 1%) Take out the materials at the time of use. 500 ml	Special structure reinforced film. Heat resistant temperature is 130°C [Type: A] 200 pcs 500 x 700 mm [Type: B] 200 pcs 620 x 820 mm Use it without closing the mouth.	Deodorizer for the "unpleasant odor" generated during sterilization of culture media etc. It melts smoothly in the sterilization process and exerts a deodorization effect. Standard amount of deodorant according to the autoclave capacity less than 40 L: 2-3 T at once from 40 L to 60 L: 4 T at once from 60 L to 100 L: 6 T at once 100 T / bottle

 

Sterilization tape, Sterilization label, Sterilization bag
Sterilization tape: Clear color change makes it easy to identify exposure to sterilization process. Sterilization label: Paste directly on the object to be sterilized, you can check the sterilization treatment. After sterilization, the letters "sterilized" appear and it can be easily distinguished from untreated materials. Sterilization bag: There are sterilization bags that are made of paper, roll type or one seal back type. Most of them are heat seal type, but tape seal type and aluminum plate seal type can be also available. Ask us for prices and more details.
