Automated sterilization of media from small to large scale operations. Seven models available from 10 - 120 liters. Systec MediaPrep is capable of sterilizing agar and cooling the media in less than 90 minutes.
Powerfull heating elements enable particularly rapid heating to be carried out. Rapid cooling is performed 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 MediaPrep agar sterilizer system will automatically fill with the correct amount of distilled water (for steam generation) prior to start of each cycle. The stirrer at the bottom of the removable media vessel mixes continuously throughout the sterilization cycle ensuring homogenous media. Rapid cooling is achieved via a sterile water dispensing ring that cools the media vessel after sterilization. Thermo labile components may be added after sterilization by utilizing the addition port.
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.
Media can be dispensed utilizing one of Microbiology International’s peristaltic pumps. For high volume dispensing the MediaPrep can be pressurized and connected to the HFD dispenser allowing flow rates of 100 ml / second.
The prepared and sterile medium is withdrawn via a flexible tube, supported either by adjustable internal pressure in the chamber and dosed via a tube valve or by a separate peristaltic filling pump. Direct connection of a filling device for petri dishes is also possible.
The internal withdrawal tube and the dispensing port are automatically steam-sterilized during every sterilization run via a patented connecting device. The part of the tube outside the vessel has to be pre-sterilized separately and connected under sterile conditions.
The filling station for additives subsequent to sterilization is generously dimensioned and has a safety lock. A permanent screw connection guarantees safe and sterile withdrawal of the medium.
Custom pre-weighed dehydrated culture media foil pouches for easy media-making.
Designed specifically for use with Systec MediaPrep. This sturdy cover fits over the MediaPrep vessel opening to prevent the usual powder media dust cloud from escaping the vessel. Thereby, preserving the instrument’s electronics and keeping your workspace clean.
