Functionalities and technical specifications

Specification	More info
Laboratory waste bags, porous solids and wrapped objects	The mechanical purge of air using the vacuum pump facilitates the posterior penetration of steam, facilitating the sterilization of porous items. At the end of the cycle, they will be dry thanks to the drying function.
Liquids and culture media	The agar mode maintains the temperature and prevents the culture media from gelling. Installing a flexible probe allows for more precise sterilization of liquid loads.
Plastic and metal objects & glassware	In programs for solid loads, the heating jacket and vacuum pump are activated at the end of the sterilization phase to completely dry the load.

Vertical laboratory autoclaves with drying

The AE-DRY Series vertical laboratory autoclaves with drying are suitable for laboratories that need efficient sterilization of solid loads with complete drying at the end of each cycle. These floor-standing autoclaves are optimized to reduce turnaround times, improve workflow efficiency, and eliminate the need for external drying equipment.

What are AE-DRY autoclaves used for?

The AE-DRY Series sterilizes a wide range of laboratory materials, including:

Wrapped and unwrapped solid loads
Porous and hollow objects
Items with complex geometries and cavities
Glassware, plastics, and metal instruments
Laboratory waste bags
Liquids and culture media (with appropriate programs)

They are suitable for industrial, educational, and research laboratory environments where productivity and cycle efficiency are important.

Features

The key feature of the AE-DRY Series is the integrated final drying function, which:

Uses a heating jacket combined with a vacuum pump
Ensures solid loads are completely dry at the end of the cycle
Eliminates the need for external drying ovens
Reduces handling time and overall process duration
Sterilization chamber and door made of AISI-316L stainless steel
Corrosion-resistant construction
Built in accordance with applicable EU quality and safety standards
Steam generation via internal Incoloy® 825 heating elements with protective grid

This makes the system particularly suitable for high-throughput laboratory environments.

How does the sterilization process work?

The AE-DRY Series uses a multi-phase sterilization cycle designed for efficiency and steam penetration.

Prevacuum phase

A vacuum pump removes air from the chamber and load
Typically performed using a vacuum pulse down to -0.75 Barg
Improves steam penetration in porous and complex loads

Heating phase

Water from the integrated tank is heated by Incoloy® 825 electric heating elements
Saturated steam is generated inside the chamber
Increased heating capacity is available in special models for faster cycles

Sterilization phase

Chamber temperature is maintained at the programmed setpoint
Controlled by a PT-100 Class A temperature probe
Optional flexible probe control available for liquid sterilization

Vacuum drying phase (solid programs only)

The vacuum pump applies multiple vacuum pulses
Heating jacket assists in complete drying of the load
Water returns to the integrated tank after use

Cooling phase

Natural cooling occurs after sterilization
An acoustic signal indicates when it reaches a safe opening temperature
In agar mode, it can maintain a selected temperature between 40 °C and 80 °C

Easy installation

These autoclaves feature plug-and-play operation:

Requires only an electrical connection
No need for dedicated plumbing or drainage
Integrated water tank supplies the chamber automatically
Manual filling of the water tank (with optional automatic network fill upgrade)

Safety features

The AE-DRY Series incorporates multiple safety features, including:

Overpressure safety valve
Thermally insulated door
Overtemperature safety thermostat
Water level sensor
Open door detection system
Pneumatic safety locking system during pressure conditions

These systems are designed to ensure safe operation during routine laboratory use.

System control

The AE-DRY Series is managed by a PID microprocessor control system with:

4 predefined programs
6 editable programs
Adjustable parameters for time, temperature, drying time, and cycle type
Support for solids and liquids sterilization modes
Optional agar mode and flexible probe control
Programmable auto-start up to 24 hours

Special models with increased heating capacity are available for faster processing.

Vertical autoclaves are loaded from the top. The chamber is oriented vertically, which means these units typically offer a larger internal capacity, allowing greater volumes to be sterilized in a single cycle. Their footprint is relatively compact, but they require adequate overhead clearance. Benchtop horizontal autoclaves are loaded through a front-facing door. The chamber is oriented horizontally, and the overall design is low-profile and compact, making these units well suited for laboratories or clinical environments where bench or floor space is limited. For more details you can read this blogpost.

A vertical laboratory autoclave with drying is used for steam sterilization of solid laboratory loads that must be completely dry at the end of the cycle. These systems are designed to improve turnaround time and eliminate the need for separate drying equipment in laboratory workflows.

Autoclaves with drying can sterilize wrapped and unwrapped solid loads, porous and hollow objects, glassware, plastics, metal instruments, laboratory waste bags, and, using specific programs, liquids and culture media.

Drying is achieved through a combination of a vacuum pump and a heating jacket surrounding the chamber. After sterilization, multiple vacuum pulses remove moisture while heat accelerates evaporation, leaving the load completely dry.

Steam must contact all surfaces to destroy microorganisms effectively. Air pockets trapped in porous or hollow items can block steam access, which is why vacuum‑assisted air removal is essential for reliable sterilization.

A typical cycle includes a prevacuum phase, heating phase, sterilization holding phase, vacuum drying phase for solid loads, and a natural cooling phase. An acoustic signal indicates when the chamber can be safely opened.
