Functionalities and technical specifications

Specification	More info
Porous solids and enveloped objects	The mechanical purge of air using the vacuum pimp facilitates the posterior penetration of steam, facilitating the sterilization of bagged items.
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.
Complex geometries	The multiple initial prevacuum pulses, in conjunction with the steam generator, ensure deep steam penetration across all surfaces.
Laboratory waste bags	The mechanical purge of air using the vacuum pump facilitates the posterior penetration of steam, facilitating the sterilization of bagged items.

Font-loading benchtop autoclaves with prevacuums and drying

The AHS-B Series benchtop autoclaves with prevacuums and drying by Raypa are particularly suitable for loads that require deep steam penetration and complete drying. These include porous solids, packaged goods, cavity-containing objects, liquids, and items with complex geometries.

They meet all the sterilization needs of industrial, educational, medical, and research laboratories to increase productivity and process all types of loads.

Waste water discharge system to reduce contamination and scaling
Optional automatic mains water connection
Programmable preheating and auto-start functions
Optional sterilization data management software
Plug-and-play installation with no plumbing required
User management with administrator control
Sterilization chamber and door are made of AISI-316L stainless steel for high corrosion resistance
In compliance with applicable EU safety and quality standards

Designed for complex and demanding sterilization loads

The system is ideal for sterilizing materials that require deep and uniform steam penetration, including:

Porous solids and textiles
Wrapped or packaged loads
Hollow objects and complex geometries
Plastics, metal instruments, and glassware
Liquids and culture media
Laboratory waste bags

Thanks to the combination of an integrated steam generator, prevacuum phase, and vacuum drying system, the AHS-B Series can handle both routine and highly complex sterilization applications.

Fast sterilizations with deep steam penetration

An integrated independent steam generator produces saturated steam rapidly, reducing cycle times. Before sterilization, multiple prevacuum pulses remove air from the chamber, eliminating cold spots and improving steam access to all surfaces.

Complete drying for solid loads

For solid cycles, a vacuum drying phase ensures that materials are fully dry at the end of the process. This is achieved through a combination of a heating jacket and a vacuum pump, removing residual moisture without the need for external drying equipment.

Operating cycle

Preheating phase: optional preheating up to 70°C can be used to reduce total cycle time
Prevacuum phase: vacuum pulses remove air down to -0.75 bar, improving steam penetration for complex loads
Heating phase: the external steam generator injects saturated steam until the sterilization temperature is reached
Sterilization phase: it maintains temperature precisely under PID control using a PT-100 Class A probe. Optional flexible probe control is available for liquid loads
Vacuum drying phase (solids only): multiple vacuum pulses in combination with a heating jacket ensure complete drying of solid loads
Cooling phase: the chamber cools naturally until it reaches a safe opening temperature, confirmed by an acoustic signal

Water and steam management

The AHS-B Series uses an integrated steam generator fed by an independent clean water tank. Sensors monitor water levels, and the system can automate filling. An optional mains water connection is available.

All cycle discharge is directed to a separate waste water tank to reduce contamination, corrosion, and scaling inside the system.

Safety features

Safety is ensured through multiple integrated protections:

Safety thermostat and temperature monitoring
Water level sensors in both tanks
Open-door detection system
Pneumatic locking system preventing door opening under pressure

A benchtop autoclave with prevacuum and drying is used for sterilizing complex laboratory loads that require deep steam penetration and complete drying. These include porous materials, wrapped and packaged items, hollow instruments, liquids, and objects with complex geometries.

Benchtop autoclaves with prevacuums and drying are intended for industrial, educational, medical, and research laboratories that need to process a wide variety of demanding loads while ensuring consistent sterilization quality and dry end results.

The Raypa AHS‑B Series combines an integrated steam generator, adjustable prevacuum pulses, and an active vacuum drying system, enabling deep and uniform steam penetration as well as completely dry solid loads at the end of the cycle. This makes it suitable for complex and wrapped items that standard benchtop autoclaves cannot process effectively.

During the prevacuum phase, multiple vacuum pulses remove air from the chamber down to very low pressure levels, eliminating cold spots and allowing steam to reach all surfaces of complex and porous loads more effectively.

The AHS‑B Series can sterilize porous solids and textiles, wrapped and packaged loads, hollow and cavity‑containing objects, plastics, metal instruments, glassware, liquids, culture media, and laboratory waste bags.

An integrated independent steam generator produces saturated steam rapidly and consistently, reducing cycle times and ensuring stable sterilization conditions without relying on external steam sources.

Yes, the AHS‑B Series is specifically designed for wrapped, porous, and hollow loads, thanks to its adjustable prevacuum pulses and vacuum drying system, which ensure effective penetration and dry results.
