CO₂ sensor drift
The most common cause of results that quietly stop being reproducible.
+4 °C to +60 °C
CO₂ & laboratory incubator service
Temperature, gas concentration and humidity all have to be right at once — and a culture will tell you when one of them is not.
Why us for this
Specialised, not general
Dustin is certified across Thermo Fisher and PHCbi product lines including incubators, which covers most of what runs in Manitoba research and clinical labs.
Brands serviced
Thermo Fisher Scientific, PHCbi (factory trained and authorized) and NuAire CO₂ incubators.
Common faults
What usually goes wrong
Most of these are progressive. Caught early they are maintenance items; caught late they are emergencies.
Humidity control problems
Too little and cultures dry at the edges; too much and you invite contamination.
Contamination recurrence
When contamination keeps returning after cleaning, the cause is usually mechanical rather than procedural.
Temperature uniformity
Shelf-to-shelf variation matters more in an incubator than almost anywhere else.
Door seal and heater faults
Condensation at the door is an early sign worth acting on.
Decontamination cycle failures
A cycle that does not complete correctly leaves you with confidence you have not earned.
Service scope
What a visit covers
- CO₂ sensor calibration and gas control verification
- Temperature calibration and uniformity checks
- Humidity system inspection and service
- Decontamination cycle verification
- Door seal, gasket and heater service
- Airflow and filtration inspection
Included with plans
Put this on a schedule
Reactive service means every fault arrives as an emergency. A preventive maintenance plan turns most of them into a line item on a calendar instead.

Questions
About co2 & lab incubators
That is a classic sensor drift presentation. Independent verification of temperature and CO₂ against the display is the fastest way to confirm or rule it out.
Yes. Dustin is listed with NuAire and has extensive experience across their product range.
Yes — a cycle that has run is not the same as a cycle that has worked.
