A laboratory incubator has one job, and it has to do it perfectly: hold a set temperature, without drift, for as long as your protocol runs. Whether you are growing a microbiological culture overnight, holding cell cultures for a fortnight or conditioning materials before testing, a variation of half a degree in the wrong part of the chamber can quietly undo weeks of work.
At Thermoline, we do not simply assemble incubators. We engineer them, in Australia, with precision, durability and everyday usability designed in from the first drawing. Every decision, from the grade of stainless steel in the liner to the placement of the temperature sensor, is made with one question in mind: will this still hold that same stable temperature on the thousandth day of use?
Here is a look behind the scenes at how that precision is built into every Thermoline laboratory incubator.
Temperature control is the foundation of every high-quality lab incubator. For microbiological research, cell culture, pharmaceutical testing or material conditioning, even a slight fluctuation can shift a result. Two specifications matter, and they are not the same thing.
Temperature stability describes how tightly the incubator holds its setpoint over time at a single point. Thermoline incubators control to ±0.1°C. Spatial uniformity describes how evenly that temperature is spread across the whole chamber, top shelf to bottom, front to back. Our benchtop and premium incubators achieve ±1.0°C uniformity in fan-forced mode and ±2.0°C in natural convection at 40°C. A cabinet can look accurate on the display and still be uneven inside, which is why we design and verify for both.
Thermoline benchtop incubators also offer something unusual in the Australian market: switchable fan-forced or natural convection. Fan-forced gives you the tightest uniformity for general microbiology and material conditioning. Natural convection avoids air movement across open plates and shallow media, which matters for delicate cultures. Most laboratories buy one incubator and end up needing both behaviours, so we built the choice into a single unit.
Not every laboratory needs the same cabinet. Capacity, temperature range and whether you need to hold below ambient are the three decisions that shape the specification. Thermoline manufactures three families of laboratory incubators to cover that spread.

A refrigerated incubator, sometimes called a cooled incubator, is the right answer whenever your setpoint sits near or under room temperature, or whenever an Australian summer means an unrefrigerated cabinet cannot reliably hold 20°C. Thermoline also builds a 200 L shaker refrigerated incubator, the TMLR-200, designed to house a laboratory shaker at a fixed +22°C with an independent external power outlet, for laboratories that need a shaking incubator arrangement without compromising uniform temperature control.
Reliability is not a goal we aim at, it is a specification we build to. A laboratory incubator that runs continuously for a decade is exposed to constant thermal cycling, daily door movement and routine chemical cleaning. The materials have to be chosen accordingly.
Because we design and manufacture at our Wetherill Park facility in Western Sydney, spare parts and service support come from the same team that built the unit. That matters more than any specification sheet when an incubator needs attention five years in.
Laboratory professionals need equipment that is reliable and easy to live with. Thermoline incubators are designed around the person operating them, not just the samples inside them.
Practical options are available too, including door locks, additional shelves and port hole modifications for probes and cabling, so the incubator fits your workflow rather than the other way around.
Quality control sits at the centre of our manufacturing process. Before any Thermoline laboratory incubator is packed for despatch, it goes through a full test sequence against our own performance standards.
Every incubator is evaluated under real operating conditions to confirm its accuracy, reliability and safety. That is the reason laboratories across Australia, including CSIRO, universities, NSW Health and government departments, specify Thermoline.
Thermoline has been designing and manufacturing laboratory equipment in Australia since 1970. When you choose a Thermoline incubator, you are investing in:
Choosing a laboratory incubator is easier when you can talk to the engineers behind it. Whether you need a compact benchtop unit for a teaching laboratory, a 1,100 L upright for a high-throughput clinical facility or a refrigerated incubator for BOD testing, the Thermoline team can help you match capacity, temperature range and convection type to the work you actually do.

Is a laboratory incubator the same as a CO2 incubator?
A standard laboratory incubator controls temperature only, and in some models humidity. A CO2 incubator adds regulated carbon dioxide to maintain the pH of bicarbonate-buffered media, which is required for many mammalian cell culture protocols. If your work does not depend on CO2 regulation, a conventional or refrigerated incubator is usually the more practical and more economical choice.
How often should a laboratory incubator be calibrated?
Most laboratories calibrate annually, though NATA-accredited facilities and those working to a quality system may calibrate every six months or align with their internal schedule. Between formal calibrations, an independent reference thermometer placed in the chamber is a simple way to confirm the controller and the actual chamber temperature still agree.
How much does a laboratory incubator cost in Australia?
Price is driven mainly by capacity, whether refrigeration is required and any customisation such as port holes or additional shelves. A small benchtop unit and a 1,100 L refrigerated cabinet sit at very different points. Thermoline quotes per configuration, so it is worth describing your application rather than shopping by list price alone.
What size laboratory incubator do I need?
Work backwards from the largest item you will incubate and how many you will run at once, then check the shelf spacing rather than the litre figure. Premium models take up to four shelves at 100 mm spacing, which suits stacked plates but not tall flasks. Allow headroom for peak workload, since an incubator packed wall to wall restricts airflow and degrades uniformity.
Can Thermoline incubators be customised?
Common modifications include door locks, extra or repositioned shelves, port holes for probes and cabling, and a choice of glass or solid doors. Because the cabinets are built in Sydney rather than imported to a fixed specification, non-standard requirements can often be accommodated during manufacture.
