Designed to provide a stable and convenient environment for cell and tissue culture, taking the most stringent needs of the cell biologist, for both continuous and batch cultures, into account. The S@feGrow 188 maintains an accurate CO2 gas concentration, uniform temperature and a consistently high level of humidity providing a stable culturing environment, even for most critical applications like IVF and Hybridoma cultures.
Accurate and precise temperature is maintained by 4 independently controlled and validated “Direct Heating” elements located on all 6 sides of the chamber which are able to control temperature down to 0.1 degree of set value.
Easy to clean: solid shelves and a seamless electro-polished 304 grade stainless steel internal chamber with large radius corners.
State of the art C02 controller, with a solid state infrared sensor with atmospheric auto zeroing of C02. Recovery of C02 concentration is achieved within 5 minutes following a 15 second long door opening.
Fanless construction, with air movement by thermal convection only, ensures a low contamination risk, simpliﬁes cleaning and decontamination and prolongs the life of the incubator components.
The optional double door design, (sealed inner glass door and outer heated door), enables the C02 incubator to be specified with a 4 or 8 inner glass door system giving users flexible access options to the chamber.
Large 27.5 mm access port allows the user to provide electrical power to small pieces of equipment inside the chamber and also provides access to the chamber for other services.
Humidity is passively maintained at 95%, thanks to a 2.5 litres stainless steel humidity tray, heated by the base heater.
Built-in “on-demand” decontamination cycle programme, for absolute safety.
A fully tested “on demand” automatic decontamination cycle, heating up to 125°C, is a standard feature assuring peace of mind when starting a culturing cycle. One advantage of the system is that there is no need to remove any of the fixtures or fittings from within the chamber. 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 concentration is automatically resumed, with the only action to be performed by the user prior to start up is the addition of sterile water into the humidity tray.
Programmable audio-visual alarm, warning “parameter out of range”. Autoreset after chamber condition recovery.
Large 2 x 24 message centre, with alpha numeric display for setup and status information
Temperature display in steps of 0.1°C.
CO2 concentration display in steps of 0.1%.
The accurate and precise temperature is maintained by means of a 4 section independently controlled and validated direct heater system. A total of 73 metres of heating elements ensures the even heating of all internal surfaces (chamber, front frame and door inner side) within the CO2 incubator. In addition, a multi R-T curve matched thermistor control system can measure and control temperature to within to 0.1°C of the set value. Over-temperature protection is independent of the controls and inhibits all heaters when the temperature rises by 1 degree above the programmed value. The recovery of set temperature (following the door being open for 15 seconds), occurs within 5 minutes, thus protecting cultures against thermal shocks (see Graph below)
