Systec Media preparators MediaPrep for up to 30 litres in Autoclaves

Systec Media preparators MediaPrep for up to 30 litres. Prepare and sterilize microbiological media. Fast, accurate and easy to handle.

Locking of the door and loading hatch is dependent on temperature and pressure. Accidental opening is not possible!
The inner vessel holder is exchangeable and easy to remove and clean.
Every MediaPrep is so equipped and controlled that it can be used as a normal autoclave.

Powerfull heating elements enable particularly rapid heating to be carried out. Rapid cooling is by water circulation and support presssure directly at the external walls of the media vessel using sterilized demineralized water. The water is brought to cooling temperature using a plate heat exchanger with a water connection. The total process time including heating, sterilizing and cooling to 50° C lasts from 60 - 120 minutes, depending on the size of the vessel, the quantity of media and the temperature of cooling water. The support pressure avoids an overboiling respectively foaming of the media. The air compressor is built-in.

An automatic process guarantees uniform, high and reproducible quality of the prepared and sterilized media. The entire process - from initial heating to mixing and sterilization at a set temperature to cooling - is microprocessor-controlled. In addition, the temperature to be maintained after sterilization can be pre-selected.

Operation is via a front panel with a large, easy-to-read display. Every Systec MediaPrep has an interface for a PC; special software enables comprehensive documentation to be prepared. MediaPrep can be optionally fitted with an integrated printer for recording process documentation or with a SD memory card.

The filling port for additives subsequent to sterilization is generously dimensioned and has a safety lock. Sterile additives can be added via the open port with the help of a Bunsen burner or via a silicone septum using a syringe.

A fixed screw connection guarantees safe and sterile dispensing of the media.

The processed and sterile medium is dispensed via a flexible tube. The inner aspiration tube and dispensing port are also sterilized by steam during each sterilization process. The part of the tube outside of the instrument and the connected dispensing adapter must be separately sterilized using a suitable steam-sterilization procedure and connected to the dispensing port under sterile conditions.

Multi-function pump Dosierfix. This system is characterized by a high degree of precision and high speed. The dosing volume can be selected from 0.1 up to 999 ml. The system operates accurately to ± 0.5 %. Its automatic calibration function by means of a sample dosing guarantees reproducible results.

Automatic tube valve. An economical method for dispensing. Whilst a pre-selectable constant slight excess pressure in the media vessel promotes flow, MediaPrep controls the opening and closing of the pinch valve. Once the desired volume has been entered, MediaPrep carries out a sample dosing operation and calibrates itself based on the viscosity of the media.
