Systec DX-Series

Steam generation by steam generator
The steam generator is integrated into the autoclave housing but separated from the sterilization chamber.

This has numerous advantages:

• No heating elements and no reservoir for dirty water in the chamber
• In conjunction with the stand-by pre-heating function, only 10 min. heating time to 121 °C with an empty chamber is required
• Improved air removal by suppressing the air to the bottom with its natural gravitation
• Quicker cooling as neither the hot water in the chamber nor the separate steam generator need to be cooled
• After cooling, steam is immediately available for the next sterilization run

Operation by Touch-Screen technology
Operation is easy and rapid via a large (5.7 inch) touch screen interface for direct reading. This innovation oers additional options and increased flexibility when working with the autoclave. For example, process data can be displayed numerically or graphically. 7 programs are pre-defined but can be expanded (up to 100) as required by the user. To create a new program, the user is guided through the process by a menu dialog. Every new program is automatically assigned to a permanent, unalterable name and can also be given an individual designation by the user. All process parameters can be individually altered.

Pre-defined programs
1 Solids
2 Waste bags
3 Liquid waste
4 Liquids
5 Cleaning
6 Vacuum test*
7 Bowie-Dick test*

These can be expanded to 100 sterilization programs.
* Only in combination with a vacuum device.

Automatic door-opening system

Easy but safe – on closing, the door is automatically locked by a circumferential ring system. A special lip seal made of heatresistant silicone provides reliable tightness; the more the steam pressure increases, the tighter the seal becomes – without the need for additional compressed air or other media! The door-locking system is temperature-controlled according to the safety requirements for electrical equipment for measurement, control, and laboratory use (DIN EN (IEC) 61010-2-040). The door remains locked as long as there is excess pressure in the chamber. The door and other parts of the pressure vessel and housing are made of stainless steel. The attractively designed front cover, which also incorporates the control panel, display and parts of the control processing system, is made of heatresistant, insulating plastic. There is no risk for the operator of coming into contact with hot components.

Automatic door opening
The autoclave door-opening works autonomously – either by pressing a button or automatically at the end of a program. A simple system but most useful in practice. Residual steam is exhausted automatically without intermission. Residual heat is used to dry the items being sterilized during a final short phase in the autoclave. Automatic door-opening is restricted to an angle of approx. 15°; this avoids possible contamination from the outside. This is especially useful when sterilized items have to remain in the autoclave for cooling and drying. Subsequently, for removing the sterilized items, the door can be completely opened manually.

Vacuum system
Typical solids are pipette tips (in boxes), empty glassware and porous materials such as filters or fabrics. The vacuum device effectively removes the air from solids, tubing, porous materials, and fabrics, allowing the steam to penetrate completely. The process includes a fractionated pre-vacuum phase in combination with the standard steam generator.

Superdry – for drying solids
This optional accessory increases the drying efficiency for solids and porous materials such as filters and fabrics. Heat energy from the standard steam generator is transferred to the heating coils around the body of the sterilization chamber and is used for drying. Deep-vacuum drying using the optional vacuum device in conjuction with Superdry avoids the necessity for subsequent drying in a separate drying cabinet.

Vacuum system
For waste in bags, it is important to completely remove the air present in the sterilization load in order to ensure accurate, reproducible, and validatable sterilization.

The vacuum device is used for the highly effective removal of air from disposal bags so that the steam can also penetrate the items to be sterilized. This is achieved by means of a fractionated pre-vacuum in conjunction with the standard steam generator. This is the only way to achieve validatable sterilization of waste in disposal bags.

Exhaust air filtration with condensate inactivation
For the sterilization of hazardous biological substances, Systec autoclaves can be fitted with an optional air exhaust filtration system. The autoclavable sterile filter, consisting of a filter cartridge with PTFE membrane of pore size 0.2 μm, is installed in a presure-proof housing and can be quickly changed at any time.

The filter is also automatically sterilized inline during the sterilization process, monitored by the PT-100 temperature sensor. The condensate is retained inside the pressure vessel during the heating and sterilization phases and thus also sterilized. Through air exhaust filtration and condensate inactivation, it is ensured that no microorganisms can escape before end of the sterilization phase.

Optional integrated printer for documentation of program type, batch number, date / time, temperature / pressure progress and sterilization phase.

Systec ADS documentation software package

Via RS-232 interface for direct connection to a PC or for connecting to an Ethernet network via converters.

Extensive documentation on up to 10,000 sterilization cycles* via an (optional) integrated card slot and a 1024 MB SD memory card (included).
* only in conjunction with optional Systec ADS software.

Mantle cooling with cooling water and support pressure
During the entire sterilization process a flexible PT-100 temperature sensor monitors the temperature in a reference vessel. It is guaranteed that the sterilization period begins only once the sterilization temperature has been attained in the liquid to be sterilized. The cooling temperature is also constantly monitored. In accordance with relevant standards to prevent delayed boiling, the lid can only be opened once the temperature of the liquid has been reduced to at least 80 °C.

Radial Ventilator 
In conjunction with optional mantle cooling with cooling water and support pressure, the radial ventilator ensures accelerated removal of heat from the sterilization items to the cooled chamber mantle.

• Reduction of cooling time by up to 70 %

Ultracooler
In conjunction with optional mantle cooling with cooling water, support pressure and radial ventilator, it is possible to significantly reduce the recooling time and the entire sterilization process by integrating of the additional ultracooler heat exchanger.

• Reduction of cooling time by up to 90 %
• Depending on the load, cooling times between 15 and 60 minutes can be achieved

Stainless steel wire mesh baskets and other accesories available upon request. All components are made of stainless steel and are cleanly welded.

To fully utilize the available space in the chamber, especially when sterilizing small items, the autoclaves can be fitted with a rack system. The entire rack system or individual trays can be removed.

There is a suitable loading table for every Systec DX-series autoclave. Precisely tailored to fit to the centimeter. With a standard loading table height of 72 cm (other heights available on request at no extra charge), the autoclave is in the right position for convenient handling. The lower shelf is practical and can be used, for example, to store the loading baskets.

Large autoclaves in particular can be easily and securely loaded using special transport and transfer carts. The items to be sterilized can either be placed directly on the transfer cart with rails or using a basket. The transport cart can be moved and docked to the autoclave and fixed in position. The handle can then be loosened to allow the transfer cart to slide into the autoclave on fixed rails.
