Why consider the LEEC Culture Safe versus other brands?
LEEC has almost 60 years experience of manufacturing laboratory incubators. LEEC developed the first CO2 incubator that automatically injected and controlled CO2 by the use of a thermal conductivity (T.C.) CO2 detector. LEEC developed and patented this world leading technology at this period in time, hence manufacturing the world’s 1st automatic CO2 incubator. As you would expect from such a forward thinking innovative company, LEEC has continued its relentless R&D programme and now offers world class leading CO2 incubators with many more built-in inherent features and advantages, whilst still remaining competitively priced. Through continued R&D development, LEEC now offers as standard, state of the art drift free infra red (IR) CO2 sensors across the complete range of ALL its culture safe models.
Why consider Drift Free Infra-Red instead of conventional thermal conductivity (T.C.) CO2 Sensors?
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.
