Media preparators of the Mediaprep-Series for preparation and sterilization of microbiological media. 10 to 120 Liters nominal volume.
Designed for preparation and sterilization of agar-containing nutrient media and other sterile liquids, with microprocessor-controlled fully automatic program sequence. The Systec Mediaprep-Series includes stronger heating elements, rapid cooling, magnetic stirring, inner vessel, temperature controlled door lock, dispensing outlet and inlet port for adding additives.

Characteristics:

Fully automatic microprocessor control incorporating 12 programs
Sterilization temperature pre-selectable up to 138°C / 3.8 bar
Novel automatic door closure with safety-lock system, lip-gasket out of silicone and opening at the push of a button
Temperature- and pressure dependent interlock for the door, inlet port and dispensing port
Thermal door lock, controlled by pressure and medium temperature according to Pressure Vessel Regulations
Pressure vessel made out of high quality pharmaceutical grade Titanium-stabilized stainless steel 1.4571 (V4A, AISI 316 Ti), electro polished, resistant against chemicals, easy to clean
Housing and basic frame construction out of corrosion resistant stainless steel
All sterilization programs with pre-selectable sterilization parameters and automatic program sequence
Rapid cooling with recirculating sterile water, heat exchanger and recirculation pump
Flexible PT-100 temperature load sensor
Sterilization time activation based on medium temperature
Electronic pressure transducer for pressure and temperature regulation
Autofill - automatic de-mineralized water feed for steam generation
Steam exhaust condensation - water-cooled with thermostatic control
Validation port
Start by clock / timer for programmable start-time
Prepared for subsequent printer connection
RS 232 interface for data transfer
Temperature holding program for keeping agar solutions warm
Base plate for vessels, baskets etc. when used as autoclave
Wheels with stop breaks for portable use
Thermal insulation out of Hanno-Tect, no risk of particle dissociation
Support frame and housing out of stainless steel
Safety pressure release valve
Safety cut off at low water level
Safety cut off at excess temperature
Additionally usable as a normal autoclave
Direct electrical heated through strong heating elements for fast heat-up
Fast cooling through recirculation of in-line sterilized de-mineralized water, cooled by a plate heat exchanger with cooling water connection
Continuous mixing through a stirrer on the bottom of the media-vessel, contact free driven by a strong magnetic motor
Permanent temperature control with a PT-100 temperature load sensor, directly inside the media
RS 232 Interface for printer connection
Inlet-nozzle with safety screw-closure for filling of additives after sterilization
Media removal through a flexible silicone tubing (either by selectable internal pressure inside the chamber and an electronically controlled pinch valve or with an optional peristaltic pump). Furthermore all filling lines for petri-dishes available on the market or other dispensing devices can be connected, without any exception. The inner filling tube and the dispensing nozzle are sterilized in-line, during the sterilization cycle
Easy cleaning and operational readiness through exchangeable, removable inner vessel. Thereby no risk of cross-contamination between the different batches
