Square Eco Autoclaves
(125 - 360 Liters)
The SQUARE ECO Range is the entry level of Square chambered autoclaves offered by Astell. The range is ideal where you are looking to sterilize basic items and is suitable for most labs sterilizing items like glassware, plastics and media etc.
Overview
This range is designed with price and economy in mind – the ECO range offers all the functionality of Astell’s standard circular range of autoclaves, but with an increased usable capacity due to a square chamber design.
The ECO range is designed to be water efficient, with Autofill and Autodrain options fitted as standard, and low in power consumption by utilising heaters in chamber across the range, all managed by the advanced color touchscreen controller.
Astell can custom build the SQUARE ECO range to your specifications. Please note the 360 litre SQUARE ECO unit is only suitable for fluid loads.

Options & Accessories:
Assisted Air Cooling
Addition of a powerful external fan to help reduce cool down times. The operation of the assisted air cooling system is controlled via the color touchscreen and is available on all models as an additional option, except for those fitted with a vacuum.
Autodrain
For use in ‘heaters in chamber’ autoclaves only. This feature can be selected on any cycle and will substantially decrease the time required to cool the chamber to a temperature where the door can be safely opened, especially when used in conjunction with Advanced Water Cooling or Assisted Air Cooling (see relevant options). At a pre-selected pressure during the cooling phase of the cycle, any remaining water in the chamber is evacuated to the drain. As the discharge water will be approx. 212F we would highly recommend that the ‘exhaust heat exchange system’ (AVC100) is ordered in conjunction with this option as well as ‘Autofill’ (AAP019) to avoid having to manually refill the chamber with water at the end of each cycle.
Autofill:
Maintains adequate water level within the chamber (for heaters in chamber models only). The water inlet is controlled by a level switch and complies with water bylaw regulations. The unit is readily connected to the water supply via a 1.5m flexible hose (supplied).
Load Sensed Process Timing
Allows the sterilization cycle to be controlled via the temperature in the center of the load (needed for liquids). A probe within the chamber is inserted into the load, and initiates the sterilization period once the probe reaches the programmed threshold temperature.
Exhaust Heat Exchange System:
For non-vacuum steam generator autoclaves and standard autoclaves with heaters in the chamber, due to the fact its primary purpose is to reduce the temperature of fluid leaving the chamber rather than steam. This option aims to significantly reduce the temperature of the exhaust/waste in situations where heat resistant drains are not present. Requires a mains water supply.
BSL-3 Compliance
Required when dealing with high-risk pathogens. A bacterial retentive filter is fitted to the exhaust ensuring nothing leaves the chamber without being sterilized (filter may vary from that pictured).
Simple Vacuum
The cycle begins with a pre vacuum, reducing the chamber pressure and removing the majority of air. A freesteaming/air purge stage then begins. After the sterilizing stage is complete, water in the bottom of the chamber is expelled and then a post vacuum takes place, removing any remaining steam from the chamber and cooling the load.
Pulsar Free Steaming
An effective method of driving air from the chamber during the preparation phase of a sterilization cycle, and offers cycle time improvements over traditional methods of air purging.
Discard Container:
Allows the user to easily load batches of normally awkward shaped items, ideal for discard loads.
Loading System Trolley
Allows the easy loading of the unit using a trolley and a truck.
Ethernet Port
Allows the visual display of the color touchscreen controller on another device. This works by using a VNC Viewer (not supplied) and a PC or other hardware capable of running VNC. It also offers the ability to save cycle logs to a server or over FTP for backup.
Integral Data Printer:
Provides a permanent and traceable record of ‘Time, Temperature, Pressure, Batch No., Cycle Name’ etc. A cycle report print-out includes provision for operator signatures. The printer can also be used to provide reports of cycle settings and servicing information.
IQ/OQ Documentation
Provides the user with blank documents for them to complete. The IQ section includes details of calibration equipment, an order acknowledgement, PED (Pressure Equipment Directive) compliance, a Declaration of Conformity, FAT (Factory Acceptance Test), a drawing schedule, ISO 9001:2015 certification, pressure vessel specification and door safety checks. The OQ documentation includes an Automatic Control Test sheet (per cycle) and Chamber Temperature Distribution (per cycle).
Remote Maintenance, Diagnostics
Enables network connection by ethernet or Wi-Fi or 3G/4G (SIM card required). Allows an Astell Service Engineer remote access to the unit’s touchscreen controller, e.g. for settings and software updates or troubleshooting.
21 CFR 11:
Enables the autoclave to comply with Data Security, Data Integrity, Traceability/Audit Trails and Electronic Signature rules. Essentially this means any change made to a cycle, option, or device parameter will require an electronic user signature. All device changes and signatures are electronically logged and saved in a file format that cannot be altered in any way.
Water Softener
Recommended in hard water areas to reduce the build-up of limescale on heaters and pipework, and particularly recommended for units with steam generators. Unit includes a separate brine tank, allowing installation in difficult or restricted positions. Requires salt. (full details, including service requirements are available upon request).
Castor Wheels:
Provide the flexibility to move the unit more freely.
Stainless Steel Fascia:
Supplied with external stainless steel panels.
