Mediaprep Media Preparators

Automatic media preparators (nutrient media preparators and nutrient media sterilizers) optimized for the preparation, sterilization and sterile filling of liquids, such as agar culture media, peptone water and buffer solutions or other sterile liquid media.

Available in seven different sizes for 10 to 120 litres of media. Featuring an improved heating performance, rapid recooling, a magnetic stirrer, an inner container, temperature-interlocked dispensing nozzles and bushings for filling and supplying additives.

The optimized automation regulates process times and ensures that the sterile media are of high quality.

Design

Simple and safe handling
All of the Systec Mediaprep’s from 20 litres are on rollers with locking brakes for transportable use, and can be positioned ideally anywhere within the laboratory. The touch display for operation, positioned at the top on the door, is clearly legible and easy to reach.

Highly effective heating and cooling Powerful heating elements ensure fast heating. The rapid cooling is effected through water circulation at the external walls of the media vessel with sterile demineralized water that is cooled with external water via a heat exchanger. The total cycle time including heating, sterilizing and cooling is between 60 and 120 minutes, depending on the vessel size, the amount of medium and the temperature of the cooling water. The sterile-filtered support pressure prevents the medium from foaming or over-boiling. A compressor is installed as standard in all Mediaprep models.

Fully programmable microprocessor control unit The fully programmable microprocessor control unit is a unique feature of the Systec Mediaprep. The automatic process ensures that the prepared and sterilized media is of a consistently high- and repeatable quality. During the process, the medium is mixed thoroughly, heated, sterilized and cooled down to the selected filling temperature. The medium is maintained at the filling temperature for the filling process.

Easy to operate Control of the door and loading hatches is temperatureand pressure dependent. Inadvertent opening is impossible. The media vessels are exchangeable, and thanks to the integrated handle grip, easy to remove and clean.

Operation by Touch Screen technology for all media preparators

Operation is easy and rapid via a large (5.7 inch), highly visible touch screen interface. This innovation offers additional options and increased flexibility when working with the autoclave. For example, process data can be displayed numerically or graphically. 7 programs are pre-defined but can be expanded (up to 100) as required by the user. To initiate a new program, the user is guided through the process by menu dialog. Every new program is automatically allocated a permanent, unalterable name and can also be given an individual designation by the user. All process parameters can be individually altered.

Safe Media Dispensing

Sterile addition of additives
It is possible to add controlled amounts of additives after sterilization via the filling port. The filling port is generously dimensioned and has a safety lock. The additives can be introduced with sterility maintained by using a bottle into the open port or with a syringe through a silicone septum embedded in the locking cap.

Sterile dispensing
The dispensing port can be opened for the sterile dispensing of the medium from the media preparator. A silicone tube is connected to the dispensing port using a dispensing lance. To ensure the sterile dispensing of the medium, the dispensing lance and the silicone tube must be pre-sterilized in an autoclave. The medium can either be dispensed using the Systec Mediavalve via sterile-filtered air pressure generated by the integrated compressor, or by connecting any commercially available peristaltic pump or a device that is equipped with an integrated pump.

Dispensing Alternatives

Systec Mediavalve – automatic tube valve
An economical method for dispensing uniform quantities. Pre-selectable constant slight overpressure in the media vessel ensures that the medium flows. Enter the desired quantity once, the vessel calibrates itself according to the viscosity of the medium via a sample dosing.

Systec Mediapump – peristaltic pump
High precision and high speed are a hallmark of this system. The dispensing volume can be set from between 0.1 ml to 99999.9 ml. The system works at a tolerance of ± 0.5% and ensures reproducible results thanks to the automatic calibration. Alongside simple manual dispensing, also individually configurable programmes are available.

Systec Mediafill – plate pourer and tube filler
The Systec Mediafill plate pourer and tube filler dispenses culture media automatically, safely and effi ciently into Petri dishes. It can be configured as an option for the most diverse of applications and, for example, be converted to a tube filler.

Other systems
Commercial peristaltic pumps and dilutors can also be connected.

Waste-water sterilizer
The Systec Mediaprep can also be used as waste-water sterilizer for the inactivation of liquids.
