What is steam sterilization?
Steam sterilization uses a steam sterilizer, or autoclave, to eliminate all forms of microbial life — including fungi, bacteria, viruses and spores. It can sterilize surfaces, fluids, medications and compounds such as biological culture media.
The process runs under set conditions: steam pressure of 1 to 5 bar and a sterilization temperature between 100 and 150 °C.
Common sterilization parameters:
- 121 °C for 15 to 20 minutes
- 134 °C for 3 to 5 minutes
These standardized parameters ensure effective elimination of microbial life and meet strict sterilization requirements across applications.

SYSTEC D SERIES
Horizontal bench-top autoclaves (front-loading), chamber volume from 23 to 200 liters


SYSTEC H & H-2 SERIES
H Series: horizontal high capacity autoclaves (front-loading) from 65 zo 1580 liters chamber volume
H-2 Series: double-door (pass through) autoclaves from 90 to 1580 liters chamber volume
What are the advantages of a steam generator outside the pressure chamber?
Steam can be generated by heating elements either inside or outside the autoclave's pressure vessel. When the steam generator is outside the pressure vessel, it remains integrated in the autoclave housing. Placing it outside offers several advantages:
- Much better process control
- Faster heat-up time
- Vacuum can be pulled to ensure 100% air removal, especially when sterilizing hollow items and waste
- The external steam generator has a smaller volume and often does not require a third party for yearly validation
- Easier to clean the pressure vessel
What is a media preparator?
A mediaprep, or media preparator, is a device very similar to an autoclave but designed specifically for media preparation. The medium is prepared directly in the pressure vessel (with an integrated stirrer) and can be pumped straight to a filling station. Advantages of using a mediaprep:
- Mediapreps are optimized for fast, safe media sterilization
- Preparation and sterilization are done in a single process
- Culture media filling can be automated
- Reduced risk of re-contamination of the culture media after sterilization
Systec Mediaprep & Systec Mediafill Solutions

Watch this video of a culture media sterilizer and automated petri-dish plate-pourer: the Systec Mediaprep agar preparator and sterilizer and the Systec Mediafill automated plate-pourer for petri dishes, bi-plates, tri-plates and test tubes. It automatically doses and fills agar into petri dishes (Ø 90, 70, 60 or 35 mm) and test tubes.
