Options for Autoclaves:

Steam Generation

The Top Loading range autoclaves comes with 'Heaters in the Chamber' as standard, however autoclaves in this range are also available in two other derivatives.

  1. Integral Steam Generator Option: The standard heaters in chamber are replaced with a 12kw integral steam generator. This option includes automatic water filling as standard (mains water supply required).
  2. Direct Steam Option - The heaters are removed from the chamber and connections are fitted enabling connection to an external on site steam supply.

 

Advanced and Simple Vacuum

A vacuum option is essential for porous loads (e.g wrapped instruments and fabrics) or other cycles where air pockets could easily become trapped within the load. Available in 2 derivatives, the AVC001s option is Astell’s advanced pulsar vacuum, which when used in conjunction with the integral steam generator and a heated jacket enables the dry output of all loads. Alternatively, the AVC002s vacuum utilizes the standard heaters in the base of the chamber with simple pre-vacuum air removal and post vacuum cooling to efficiently sterilize porous loads, but without any drying capability.

 

External Jacket Heating

Requiring the steam generator (or direct steam supply) option (and normally in conjunction with the vacuum option), external jacket heating effectively adds an additional layer to the outside of the autoclave chamber. This can then be independently heated by the steam supply to allow drying to take place at the end of a cycle, or can be flooded with water during cooling to aid cooling times.

 

Integral Data Printer

This printer provides a permanent and traceable record of: ¨Time ¨Temperature ¨Pressure ¨Batch No. ¨Cycle Name. There is also provision for operator signature; the printer also provides reports of cycle settings and servicing information. See example here: Example printout

 

Load Sensed Process timing

Load Sensed Process Timing allows the sterilization cycle to be controlled via the temperature achieved in the centre of the load. The operation of load sensed process timing is controlled via the ‘Logi’ touch screen controller. A ‘wandering’ probe, situated within the chamber is inserted into the load, or load simulator, and initiates the sterilization period once the probe reaches the programmed threshold temperature.

 

RS232 Interface

The addition of the RS232 option allows cycle progress to be monitored (via HyperTerminal) on an external computer equipped with suitable software.

 

Ethernet Interface

The addition of the Ethernet interface allows the visual display of the colour touch screen controller on another device. This works by using a VNC Viewer (not supplied) and a PC or other hardware capable of running VNC.

 

IQ/OQ Documentation

The IQ/OQ documents package 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 9001:2008 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)

 

Air Ballast

Air ballast is especially useful for fluid cycles as it provides controlled reduction of the chamber pressure during the cooling phase. Effectively this prevents the ‘boiling over’ of bottled fluids that is frequently associated with rapid cooling systems.

 

Assisted Air Cooling

A powerful external fan helps to reduce cool down time. The operation of the assisted air cooling system is controlled via the ‘Logi’ colour touch screen and is available on all models as an additional option, except for those fitted with a vacuum.

 

Advanced Water Cooling

Water is circulated through cooling coils in direct contact with the outside of the autoclave chamber, resulting in the rapid decrease of the internal chamber temperature. Advanced water cooling offers substantial time saving and is ideal for the busy Laboratory.

 

Autofill Option

The ‘Autofill’ option automatically 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).

 

 

Autodrain Option

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 the advanced water cooling or assisted air cooling (as detailed above). 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. 100°C we would highly recommend that the ‘exhaust heat exchange system’ (AVC100) is ordered in conjunction with this option as well as the ‘Autofill’ (AAP019) to avoid having to manually refill the chamber with water at the end of each cycle.

 

Morrison Discard Containers

Morrison Discard Containers are available in two sizes as follows:

  • 390mm diameter x 355mm high
  • 390mm diameter x 500mm high

Please note: The image shown may refer to a different Morrison Discard Container to that supplied

 

Stainless Steel Basket

Stainless Steel Baskets are available in two sizes as follows:

  • 400mm diameter x 220mm high
  • 400mm diameter x 400mm high

Note: Image refers to a different Stainless Steel Basket

 

Water Softener

Recommended to reduce the build-up of limescale on heaters and pipework etc, 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)

 

Exhaust Heat Exchange System

The exhaust heat exchange system is only for standard units with the heaters in the chamber, due to the fact it's primary purpose is to reduce the temperature of fluid leaving the chamber rather than steam. This option to significantly reduce the temperature of the exhaust/waste in situations where heat resistant drains are not present. N.B. Requires a mains water supply.

 

Category 3 Compliance

Category 3 compliance is often required when dealing with high risk sterilization requirements. A bacterial retentive filter fitted onto the exhaust ensuring nothing leaves the chamber without being sterilized.

Note: Filter may vary from that pictured.

 

 

Condensate Bottle (63L Classic Models Only)

The condensate bottle can be connected to any of the ‘Classic’ compact units to allow up to 4 litres 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 ‘Autofill’ version(s).
