• Temperature and pressure range (standard): up to 140 °C, 4 bar absolute pressure
• Touch screen control (large 5.7-inch interface) for operation, numeric and graphical process display
• Number of sterilization programs: up to 100 (7 pre-defined)
• Code-secured access rights for parameter changes and safety-relevant interventions
• Internal memory capacity for storing data backups for at least 10 years
• Timer for programmable start time
• Additional temperature sensor in condensate exhaust
• Flexible PT-100 temperature sensor (class A) for reference vessel monitoring
• Special program for Durham tubes
• Special program for destructive sterilization with fractional heating for improved venting
• Calculation of F0 value
• Waste water temperature is water-cooled and thermostatically controlled
• Adjustable automatic opening of the door at end of program (approx. 15° automatic opening restricted for safe cooling/drying)
• User account control (standard: three pre-configured user groups: Administrator, Operator, Supervisor)
• Validation port for introducing measuring equipment
• Integrated batch documentation with export as PDF and CSV
• Time synchronization with time server via network/internet

Available options (selection)

• Extension of temperature and pressure ranges to 150 °C / 5 bar absolute pressure (can be retrofitted)
• Rapid cooling systems for efficient and safe cooling of liquids
• Radial ventilator and Ultracooler to speed up cooling (mounted in chamber door so usable space not reduced)
• Mantle cooling with cooling water and support pressure (to reduce recooling times)
• Vacuum system for validated sterilization of solids and waste in disposal bags (fractionated pre-vacuum)
• Superdry for drying solids (only in combination with vacuum system)
• Exhaust air filtration including condensate deactivation for sterilization of hazardous biological substances
• Exhaust air filtration and condensate inactivation (autoclave sterile filter with PTFE 0.2 μm membrane)
• Integrated printer for batch documentation (optional)
• Save to Folder (automatic export to FTP/SFTP/FTPS) and network documentation options
• Advanced CFR 21 Part 11 solution including AuditTrail, electronic signatures and extended user account control (optional)

Technology & Operation

• Steam generation: integrated steam generator separated from the chamber. Advantages include no heating elements/reservoir in chamber, short heating time (with stand-by pre-heating: approx. 10 min to 121 °C with empty chamber), improved air removal, quicker cooling and immediate availability of steam after cooling.
• Condensation of exhaust steam via PT-100-regulated cooling system to protect waste water piping and prevent odors.
• Operation by touch-screen allows creation and naming of programs, graphical/numerical display of process data, and full parameter control.
• Pre-defined standard programs: Solids, Waste bags, Liquid waste, Liquids, Cleaning, Vacuum test*, Bowie-Dick test* (*in combination with vacuum device). Expandable up to 100 programs.

Sterilization of liquids - cooling

• Combined temperature and pressure regulation reduces heat-up times for liquids (up to 50% shorter heat-up as standard).
• Optional rapid cooling systems (ambient air ventilation, mantle cooling with cooling water, mantle cooling + support pressure, radial ventilator, Ultracooler, spray cooling with recirculated sterile water) significantly reduce cooling times and prevent boiling/loss of culture media by using sterile-filtered support pressure during cooling.
• PT-100 reference vessel monitoring ensures the sterilization period begins only when liquid reaches target temperature; lid opening is restricted until liquid cools to safe temperature (≥ 80 °C) to prevent delayed boiling.
