The LEEC IR CO2 sensor offers the latest technology and is completely drift free. T.C. CO2 sensors only measure accurately at the desired 88-92% relative humidity (%RH). After the inner glass door is opened the T.C. sensor is measuring inaccurately up to a period of 1 hour after the door closure. TC technology is much older technology and its huge disadvantage is that accurate % CO2 can only be achieved once the relative humidity (%RH) has recovered back to 88-92%RH, which is typically up to 1 hour. For very important samples and cell lines this is simply not acceptable. The pH level of the culture media will not recover and cell desiccation may result as a consequence.
All LEEC Culture Safe CO2 incubators are fitted with a premium quality state of the art drift free infra red CO2 sensor. This ensures accurate CO2 measurement at all instances in time and total peace of mind that your samples are culturing at the correct %CO2 level all the time. This eradicates the need for any additional auto-referencing / zeroing of the CO2 sensor which is sometimes necessary on other manufacturers incubators to stop drifting of CO2 calibration and carries the heavy the risk of contamination introduction into the incubator each time the auto-referencing / zeroing is performed.
LEEC has developed a clever six sided heating system controlled by using a state of the art PID controller. There is also independent control of both the door and the base (located under the water tray) allowing for extremely accurate and precise control of temperature inside the inner chamber. This precise control eliminates the need for a fan (refer to benefits of fanless) and is accurately achieved by the most gentle convection of air movement inside the chamber. This prevents any turbulence and possible rapid spreading of contamination introduced into the chamber by the higher turbulent air flow created by fan assisted incubators.
Another great benefit is a much larger internal chamber capacity against rivals with fans fitted with considerably smaller external dimensions. The LEEC Culture Safe CO2 range with its very compact external dimensions will comfortably sit on a laboratory bench or even under the laboratory bench if more convenient, many other brands are simply too large to fit in either location.
