Laboratory waste bagsFor this application, the sterilization time should be extended, chemical and/or biological tests should be used to validate the correct sterilization of the load.
Liquids and culture mediaThe 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 & glasswareActivating the rapid steam release button allows for faster cooling in solid loads.

Vertical autoclaves without drying

The AES Series vertical laboratory autoclaves without drying by Raypa are designed for economical and straightforward sterilization of a broad range of laboratory materials. These top-loading floor-standing autoclaves are intended for general laboratory use in industrial, educational, and research facilities where reliable sterilization and simple operation are required.

What can the AES Series sterilize?

The AES Series is suitable for sterilizing both solid and liquid laboratory loads, including:

  • Culture media and liquids
  • Glassware
  • Plastics and metal utensils
  • Laboratory waste bags
  • General laboratory items

The systems are designed to support routine laboratory sterilization while optimizing laboratory productivity.

What makes the AES Series suitable for general laboratories?

The AES Series combines simple operation with durable construction and low resource consumption. Key characteristics include:

  • Economical and robust design
  • Plug-and-play installation
  • Low consumption of water, energy, and operator time
  • Simple maintenance requirements
  • Stainless steel construction for durability and corrosion resistance

The sterilization chamber and door are manufactured from AISI-316L stainless steel, while the external structure is also built in stainless steel.

How are sterilization cycles controlled?

The autoclaves use a PID microprocessor controller with:

  • 4 predefined programs
  • 6 editable programs
  • Adjustable sterilization time and temperature
  • Selection of sterilization cycle type

Additional optional features include:

  • Agar mode for temperature holding
  • Flexible temperature probe control for liquids
  • Programmable auto-start up to 24 hours in advance

Sterilization options

The AES Series supports several sterilization configurations for solids and liquids.

Available functions include:

  • Standard solid and liquid sterilization cycles
  • Optional flexible core probe for liquid sterilization
  • Adjustable temperature holding between 40 °C and 80 °C for culture media (agar mode)
  • Manual steam release push-button to accelerate cooling during solid load cycles

Special models with increased heating capacity are also available for faster heating and sterilization phases.

Heating system

Steam is generated by Incoloy 825 electric heating elements positioned inside the sterilization chamber and protected by a safety grid. This configuration provides direct steam generation within the chamber for routine laboratory sterilization applications.

Easy installation

There's no need for dedicated plumbing or drainage connections. The AES Series is a plug-and-play equipment and only requires an electrical connection for operation.

Additional installation and usability features include:

  • Operation without a dedicated drain
  • Casters for easy mobility
  • Optional embedded or external printer
  • Optional software for sterilization data management

Safety features

The AES Series incorporates multiple operator safety systems, including:

  • Overpressure safety valve
  • Thermally insulated door
  • Overtemperature safety thermostat
  • Open door detection system
  • Pneumatic safety system that locks the door while pressure remains inside the chamber

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, read this blogpost.

A vertical laboratory autoclave without drying is used for routine sterilization of solid and liquid laboratory materials. These systems provide reliable steam sterilization for general laboratory workflows where active post‑cycle drying is not required.
These autoclaves are suitable for sterilizing culture media and liquids, glassware, plastics, metal utensils, laboratory waste bags, and general laboratory items. They are designed for everyday sterilization tasks in educational, research, and industrial laboratories.
PID control maintains precise temperature regulation throughout the sterilization cycle. Stable temperature control is essential to ensure effective microbial inactivation while preventing overheating or inconsistent processing.
Liquid sterilization can be enhanced using an optional flexible temperature probe placed inside a reference container. This allows the system to monitor the actual liquid temperature rather than relying only on chamber temperature, improving accuracy.
Agar mode allows controlled temperature holding between 40 °C and 80 °C after sterilization. This prevents culture media from solidifying prematurely and supports safe handling and preparation of agar‑based media.
