Simple and safe handling
All of the Systec Mediaprep’s from 20 liters 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 fl exibility when working with the autoclave. For example, process data can be displayed numerically or graphically. 7 programs are pre-defi ned 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.

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 The prepared and sterile medium is dispensed via a flexible tube. The internal aspiration tube and the dispensing port are also automatically sterilized as part of each sterilization process via the inlet of steam. The tube separate to the vessel and the dispensing adapter connected to the tube must be pre-sterilized using a suitable steam sterilization process and must be connected to the dispensing port under sterile conditions.
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.
Commercial peristaltic pumps and dilutors can also be connected.
Optional integrated printer for documentation of program type, batch number, date / time, temperature / pressure progress and sterilization phase.
Systec ADS documentation software package
Via RS-232 interface for direct connection to a PC or for connecting to an Ethernet network via converters. Special software for Windows for documentation of all process flow data such as pressure, temperature, time, and sterilization phase including relevant diagrams. The Systec ADS documentation software processes documented data both graphically and numerically.
Extensive documentation on up to 10,000 sterilization cycles* via an (optional) integrated card slot and a 1024 MB SD memory card. All the recorded data is available, via the SD memory card, for processing with the Systec ADS documentation software.
*only in combination with the optional Systec ADS software.
Systec ADS CFR documentation software package with conformity to FDA 21 CFR Part 11
Optional documentation for the Systec Mediaprep models. Download of the process flow and audit trail data from the media preparators. This solution ensures documentation according to the provisions of the FDA 21 CFR Part 11. The Systec ADS documentation software with conformity to FDA 21 CFR Part 11 processes the documented data, both graphically and numerically.
AuditTrail allows you to set up and administer the users of the Systec Mediapreps. You can specify which user can perform which actions on five different authorization levels. In addition, the access rights for the stored sterilization programs can be specified individually. The user must log in with a username and password before each action. All the actions carried out (e.g. the changing of parameters, or the starting or stopping of sterilization programs) are documented and can be traced back to the user responsible, and can also be identified by a time-stamp (date and time). All the data generated by the user’s actions or by the documentation of a sterilization cycle are protected against manipulation and marked with the electronic signature of the respective user.
