STERILAB - detailed description

STERILAB, a steam sterilizer with a chamber volume of 25 liters and gravitation deaeration of the chamber (without an air pump), represents a completely new generation of small steam sterilizers for laboratories.


The unit has been designed for the sterilization of solutions in open and closed bottles, unwrapped solid non-porous items made out of metal and glass; for the sterilization and thermal preparation of laboratory matters – agars, solutions, and the like. The unit is standardly fitted with a flexible PT 100 sensor; the unit can also be optionally fitted with forced cooling of solutions after sterilization. A wide range of software and the possibility of individual program modifications allows for extensive application of the unit. Thanks to how small they are, a big sterilization chamber, their top quality and wide range of use, STERILAB units are suitable for use at all those workplaces, where top quality, speed, reliability and the highest level of sterilization safety are required.

Basic design elements

The pressure chamber, door panel and steam generator are made out of first-rate stainless steel (ČSN 17 347, DIN 1.4571, AISI 316 Ti). In order to save energy and minimize heat radiation, the chamber is perfectly insulated with ecological insulating material. Sensors, valves, and other important design elements are manufactured by leading world producers. The unit is fitted with a pump to fill the distilled water supply tank and it does not need to be connected to water discharge piping. 


Right of change of construction and design reserved.


Saves time and water consumption and provides for comfortable operation

  • Compact dimensions and low weight
  • Optimal effective output
  • Quick steam generation system
  • Several sterilization programs that can be selected depending on the type of sterilized material
  • Users can set-up the programs
  • User programs are saved and made easy to use thanks to chip cards
  • Flexible temperature sensor for measuring the temperature in the solution • The switching-on and starting of the unit program can be time-delayed
  • In what concerns programs with controlled cooling: Material can be removed any time during the tempering phase after a of temperature 50 – 60°C has been reached.

Ergonomics and quality at the highest level

  • Sterilization chamber with a heated jacket and a separate steam generator made out of first-rate stainless steel (DIN 1.4571, AISI 316Ti)
  • Automatic door closure
  • Touch display (graphic LCD)
  • Heat is removed away from the sterilizer with the help of a powerful cooling system that does not need to be connected to a water source
  • Automatic microprocessor control through two microprocessors
  • Built-in separate tanks (6.5 liters) for demi-water and waste water big enough for at least 5 sterilization cycles with maximum possible load
  • Indication of maximum / minimum supply water level and maximum waste water level
  • Batch counter
  • RS 232 interface; an external printer can be connected for documentation of sterilization processes
  • An external computer can be connected for documentation of sterilization processes with the help of communication software
  • Communication software for PC under Windows for documentation of operating parameters
  • The configuration of sterilization program parameters can be changed with software


Safety equipment

  • two microprocessor control system (Master-Slave) of sterilization
  • Mechanical and electric door blocking system with micro-switches
  • Door blocking system controlled by the value of overpressure, temperature and by the presence of the solution in the sterilization chamber
  • If the program is turned off, the system will automatically go into safe mode
  • Warning and error reporting is controlled by a microprocessor
  • Anti-bacterial filter safely secures the quality of chamber aeration after the under-pressure cooling phase
  • Safety valve protection against surpassing maximum operation over-pressure, thermal fuse protection against non-permissible overheating of the chamber jacket electric heating and against non-permissible operation of the steam generator without water


Conformity with European standards

  • The STERILAB small steam sterilizer – complies, without exception, with the technical and legislative regulations of the Czech Republic and the EU.
