Leading Pharmaceutical Company double checks Incubator CO2 with Portable G100

Using a G100, Pfizer found some variations in the conditions of their 25 incubators, with some up to 3% in CO₂ concentration, mainly as a result of frequent opening and closing of incubator doors. Identifying this led to fine-tuning and ensured target CO₂ and O₂ concentrations were maintained.

"Now we can double check and every month we do a QC check to be sure the CO₂ is at 5%," said Tim Stroud, Associate Scientist at Pfizer in the UK. "Checking an incubator by attaching the G100 to a sample port only takes a couple of minutes so we can do all 25 within an hour. What prompted us to buy the G100 was some variable data we had been getting from an experiment, which we thought could be due to fluctuating CO₂ concentrations and we wanted to determine if that was the case,” he added.
