Laboratory Autoclave Sterilizers (109 - 430 Liters)
The Laboratory SQUARE autoclave sterilizers include a powered sliding door, liquid ring vacuum pump and ASME ‘U’ stamped jacketed pressure vessel as standard. With a temperature range of 219°F to 275°F, they are particularly suited to the decontamination and sterilization of laboratory products.
Astell’s square section autoclaves are regularly used in scientific research labs, production process manufacturing, veterinary, healthcare, food and beverage industries and more.
Overview
The Astell SQUARE laboratory autoclave sterilizers range is available in 109, 249 and 430 liter capacities. Each is ready to accept a site steam supply (50 – 80 psi). If site steam is not available then an optional steam generator can be added. All units feature Astell’s standard color touchscreen controller with digital temperature and pressure displays, cycle selection, password security, and continuous data archived up to 5,000 cycles.
This laboratory autoclave range is designed with flexibility in mind – the inclusion of a jacketed pressure vessel and vacuum system means each autoclave is capable of sterilizing a wide variety of load types.
Applications may include the sterilization of:
- Wrapped and unwrapped hard goods
- Porous and non-porous hard goods
- Liquids in unsealed open containers
- Biohazardous waste
- Animal feed
- Animal bedding
- Bowie Dick
- Leak test
📄 Model: U-AVS109D (109 liters – chamber (W)16″ x (H)16″ x (D)26″)
📄 Model: U-AVS249D (249 liters – chamber (W)20″ x (H)20″ x (D)38″)
📄 Model: U-AVS430D (430 liters – chamber (W)26″ x (H)26″ x (D)39″)
Options & Accessories:
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.
5-Position Shelf Rack
Allows the user to vary what they are sterilizing in the autoclave by moving the positioning of internal shelves.
Spare individual shelves also available separately.
Condensate Bottle (for classic models only):
A condensate bottle can be connected to any of the ‘Classic’ compact units to allow up to 4 liters of water collection during the freesteaming stage. This option is useful in situations where no easy drainage is available, as a lower cost alternative to the ‘Ecofill’ version(s).
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.
Morrison Discard Container:
Allows the user to easily load batches of normally awkward shaped items, ideal for discard loads.
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).
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.
