Sterilizers for the pharmaceutical industry, research and laboratories Flexible solutions for unique applications MMM. Protecting human health.

MMM sterilizers – individual in design, equipment and processes Each application area of a sterilizer is unique – be it in the microbiological laboratory, in animal houses or the development and production of the pharmaceutical industry. This is why MMM equipment is individually adapted to the special requirements of our customers and offers maximum safety, reliability and convenience. In personal consultations, we develop solutions in which every detail is the perfect response to the special needs of our customers. MMM sterilizers have a highly modular design so that each piece of the...

The perfect process for each application The following processes are primarily used in the laboratory and industrial area: Saturated steam process • Pre-vacuum process with drying (for solid products) • Fractional vacuum process with drying (for porous products) • Pre-vacuum process without drying (for liquids in open or loosely closed receptacles) Steam-air mixture process for liquids in sealed receptacles Pre-vacuum process without drying for liquids in sealed receptacles Solid load, e.g. heat-resistant items with plain surface, such as glassware, cages, ... Porous load / items that are...

Absolute pressure (mbar) Solids with simple surfaces (such as instruments, cages, glassware etc.) are efficiently and effectively sterilized with pre-vacuum processes. Firstly, the air is removed from the chamber and then the saturated steam is fed in until a specified sterilizing pressure has been reached. After the sterilization phase, the treated product is dried by vacuum. The temperature range for the sterilizing phase can be set between 105 °C and 134 °C. Pre-vacuum process with drying Absolute pressure (mbar) For products with porous surfaces (such as laboratory clothing, filters,...

Absolute pressure (mbar) One particular challenge for the process control is posed by sterilizing liquids in sealed receptacles. The pressure inside tightly sealed receptacles rises significantly due to the liquid expanding in the heating phase. To prevent the receptacle from distorting or rupturing, compressed air is used to build up a cushioning pressure in the chamber corresponding to the pressure inside the container. A mixture of steam and air is used as a heat transfer medium. To improve the heat transfer and achieve an even temperature distribution, the mixture of steam and air is...

Sophisticated concepts – from start to finish Convincing construction design All the functional benefits are evident once the sterilizer has been installed in the workflow at the place of operation. However, it is often the transport which presents the first hurdle. This is why we at MMM have also considered the transport, assembly and the workflow on-site. The frame of MMM sterilizers can be transported in single parts through narrow corridors and gangways and assembled at the place of operation. Its compact Simple installation design is content with an installation width of just 1600 mm,...

Customized sterilizing chamber The central component of every steam sterilizer is the sterilizing chamber. The interior walls of the cubic pressure vessel from MMM are made of stainless steel (1.4404 / AISI 316L) with peripheral ring channels as jacket (1.4571 / AISI 316Ti). MMM designs their own pressure vessels and manufactures them in their own production plants. as manufacturing sterile products in the pharmaceutical industry, all the chamber components, or only those requested by you, are designed in accordance with the HDConcept by MMM (hygienic design). This means that the chamber...

Doors and locking mechanism The automatic doors are equipped with a safety system of double pressure sensors and position switches which prevent the electrically driven sliding doors from opening while the program is in operation or under pressure. The touch-sensitive safety bar provides protection from clamping – whether it is the operator or a product to be treated obstructing the door track. compressed air used for liquids programs increases the service life of the seal due to the lower thermal load, while the steam applied for vacuum programs offers more safety in the procedure if there...

SANIcirc - pipes that make a difference Pipes, valves, connectors, seals etc. with direct contact to the sterilizer medium have an immediate impact on the outcome of the sterilization. The more valuable and sensitive the treated product is, the more important the quality of the components in the model. This is why we at MMM first make a distinction between the area which comes into contact with the product and the area which does not. The area in contact with the product includes all areas of the unit that are either directly or indirectly in contact with the product via the media, such as...

Effective cooling For reasons of safety, sterilized liquids may only be removed from the chamber once their temperature has fallen down to below 80 °C. Various methods are available to do this depending on the application. Passive cooling - natural cooling If you only sterilize liquids occasionally it is preferable to leave it overnight, without using any other medium to cool it down to the required temperature. This takes time but not resources. Active cooling - jacket cooling If the cooling process needs to be accelerated, softened cold water is fed into the pressure vessel jacket during...
