High quality medium for the cultivation of bacteria is at the core of various routine applications in today’s laboratories. Hence, many downstream tasks and results directly depend on the performance of media preparation. Furthermore, an efficient process flow is important. This not only allows laboratories to save labour costs, but also frees manpower for less repetitive tasks.

The MEDIACLAVE product range is designed to approach these needs. It allows the rapid and gentle sterilization of 1 – 30 L culture medium. Precise controlling and monitoring of temperature, time and pressure during the sterilization process guarantee constant high quality. The intuitive graphical user interface and the simple programming make it very easy for everyone to operate MEDIACLAVE.

MEDIACLAVE allows you to be flexible – culture medium of high quality is rapidly available whenever needed. This minimises the needed storage room, eliminates the management of shelf life time and therefore guarantees constant high medium quality.

Medium Formulation

MEDIACLAVE is quickly set up. Insert the cuvette (container for media), fill in the coupling water (water jacket between the cuvette and the vessel for efficient heat transfer) and you are ready to prepare your culture medium.

Culture medium can be suspended and dissolved directly within MEDIACLAVE. The strong magnetic stirrer guarantees homogeneous mixing within the vessel and prevents coagulation.

Alternatively, culture medium can be dissolved and pre-swelled using the WATER BATH operation mode prior to sterilization. The intuitive, multilingual graphical user interface makes it very easy for everyone to use MEDIACLAVE – no special training of the staff is required.

Up to 50 programs with user-defined parameter settings such as sterilization temperature, sterilization time or dispensing temperature can be saved and recalled.


High Operational Safety

An automatic tightness check at the beginning of each sterilization cycle prevents the instrument from starting if the system is not tight – avoiding incomplete sterilization and subsequent media rejection. Furthermore, MEDIACLAVE is equipped with several independent monitoring systems for pressure and temperature, guaranteeing highest safety standards for the user and the working environment. The vessel lid is equipped with an autonomous overpressure safety valve and a burst disc in case all other electronic monitoring systems fail.

Fast Heating

Powerful heating elements permit fast media processing. This minimises thermal stress and ensures high fertility of your culture medium. Pressure and temperature controlled deaeration guarantees saturated steam in the vessel.

Reliable Sterilisation

The large and strong magnetic stirrer with adjustable speed and reversing rotation direction ensures homogenous media preparation over a wide viscosity range. A Pt-1000 temperature probe and microprocessor control of process parameters allow reproducible and complete sterilization of culture media.

Rapid Cooling

Rapid cooling is enabled by an efficient plate heat exchanger. The separation of the cooling water system and the sterilization chamber makes it unlikely that culture media gets contaminated by cooling water. The built-in support pressure system prevents a delay in boiling during the rapid cool down phase, allowing an extraordinary fast and gentle cooling.
