COMFORT FOR YOUR CULTURES IS GUARANTEED... A NUMBER OF FEATURES DESIGNED TO EASE YOUR WORK Precise control and recovery of set temperature The accurate and precise temperature is maintained by means of a 4 sections independently controlled and validated Direct Heater system. A total of 73 meters of heating elements ensure even heating of all internal surfaces (chamber, front frame and door inner side); on top of this, a seven RT curve matched thermistors control system can measure and control temperature within to 0.1°C of the set value. Over-temperature protection is independent of the controls and inhibits all heaters when the temperature raises by 1 degree above the programmed value. The recovery of set temperature, after 15 seconds door opening, occurs within 5 minutes, thus protecting cultures against thermal shocks ( see Graph) The direct heated, single door, magnetic closure S@feGrow CO2 incubator (Italian design) assures to the users an easy and quick access, without any loss of operational stability and performance. Choosing the double door design, with fully sealed inner glass door and outer heated door, the CO2 incubator can be equipped with an optional 4 or 8 inner glass door system to give you unmatched choice. Left opening door option, factory installed, allows for optimal placement of the CO2 incubator in an expensive and crowded lab space. Optional multi-position shelf rack set, allows up to 8 shelves to be used, optimizing the area available for culture vessels. Solid shelves are supplied as standard to provide even surface for the culture vessels however, at no extra cost, the traditional perforated shelves can be supplied. Fanless construction, with gentlest possible air movement by thermal convection, ensures low contamination risk, simplifies cleaning and decontamination and allows for long life of incubator components. Seamless, electro-polished, Stainless Steel 304 internal chamber (with fully rounded corners and no internal projections or holes) makes it easy to clean, corrosion resistant and minimize contamination risk. Large 27.5 mm access port allows user to supply power to small instruments placed on the interior, or allows any other utilities access to the incubator chamber. Precise control and recovery of set CO2 percentage The CO2 percentage is maintained within the chamber, thanks to a stateof-the-art controller, with a solid state infrared sensor with atmospheric auto zeroing of CO2. Mixing of air with inlet CO2 gas is gently achieved, thanks to the complete absence of a forced air fan circulation system, enhancing a fast recovery of set CO2 percentage within 5 minutes, following a 15 seconds long door opening (see Graph) Fully automatic 12 hours decontamination cycle A fully tested “on demand” automatic decontamination cycle, heating up to 125°C, is a standard feature assuring your peace of mind when you start your culturing cycle. The beauty of the system is that there is no need to remove any parts or fixtures whatsoever. The total decontamination cycle is run overnight, with a 1.5-2.5 hour temperature ramp up time, a 4 hour exposure time and a 5-7 hour temperature ramp down time, totalling between 11-12 hours in average, depending upon the room temperature. At the end of the cycle, normal control of the CO2 is automatically resumed, and the only action to be performed is the addition of sterile water into the humidity tray before start up. High temperature uniformity during decontamination cycle Uniform heating to 125 ° C for 4 hours, ensures a reduction in bacterial load equal to 12* log, applied for substantially the same surgical instruments (* Bacillus subtilis var. Niger ATCC # 9372). The graph shows data from the sensor inside the chamber. Standard results in normal working conditions The graph shows data from the sensor inside the chamber.
