Operation requires a stable ambient temperature between +5 and 35°C and a dedicated AC220V 50Hz power supply. The stainless steel chamber with rounded corners should be cleaned with non-abrasive agents to prevent corrosion and maintain hygienic conditions.
- Temperature Fluctuation Limits: The incubator maintains temperature fluctuation within ±0.5°C at high temperature and ±1.0°C at low temperature, requiring minimal door openings during operation.
- Power Supply Requirements: Connect the unit to a grounded AC220V 50Hz power outlet capable of supplying 1600W continuously.
- Ambient Temperature Constraints: The ambient temperature must be maintained between +5 and 35°C to ensure proper cooling and heating performance.
- Chamber Cleaning Protocol: Clean the mirror stainless steel chamber using non-abrasive, mild cleaning agents and soft cloths to prevent surface damage.
- Timer Operation Limit: The built-in timer allows programming from 0 to 5999 minutes for timed incubation or holding cycles.
This incubator provides controlled temperature from -20 to 65°C for cultivation and preservation. Follow these steps to set up and run a typical incubation cycle.
Required Equipment:
- Place Incubator
Verify that the incubator is placed on a level surface within the ambient temperature range of +5 to 35°C. - Connect Power
Connect the power cord to a grounded AC220V 50Hz electrical outlet. - Set Temperature
Set the desired temperature setpoint using the microcomputer liquid-crystal controller interface. - Load Samples
Arrange the included shelves to accommodate sample containers and load the samples. - Program Timer
Program the timer for the required incubation duration, up to 5999 minutes, and start the cycle.
What is the temperature fluctuation tolerance for the 250L low-temperature incubator at high versus low setpoints?
The incubator specifies a temperature fluctuation of ±0.5°C at high temperatures and ±1.0°C at low temperatures, with a resolution of 0.1°C. This asymmetry reflects the greater thermal control challenge when operating below ambient, particularly during compressor cycling at sub-zero setpoints.
Can the 250L low-temperature incubator be integrated with external data logging or remote monitoring systems?
Yes, optional RS485 communication and USB data transfer interfaces are available for selected configurations, enabling external recording of temperature changes. An embedded printer accessory is also offered for on-site logging. These options require lead time and should be confirmed before ordering.
What are the electrical and footprint requirements for installing this 250L low-temperature incubator?
The unit requires an AC220V 50Hz power supply with 1600 W input power. Overall dimensions are 740×900×1580 mm, and the chamber measures 600×500×830 mm. The ambient operating temperature range is +5 to 35°C, so the unit should be placed in a climate-controlled laboratory space to maintain rated performance.
The 250L low-temperature incubator (SKU AF-LE-E-LTIN-0250-2CA5) provides a -20 °C to 65 °C range and 0.1 °C resolution, with temperature fluctuation of ±0.5 °C at high setpoints and ±1.0 °C at low setpoints, making it suitable for sub-ambient cultivation, preservation, and stability testing; however, its 1600 W power draw and required AC220V 50 Hz supply impose specific electrical infrastructure needs, and the 600×500×830 mm chamber with 3 standard shelves limits scalable throughput without accessory reconfiguration.
Positive
- Sub-ambient temperature control range: The -20 °C to 65 °C range extends usability into low-temperature incubation, sample preservation, and stability testing tasks that typical constant-temperature incubators cannot support, broadening application scope beyond near-ambient-only operation.
- 0.1 °C temperature resolution with bidirectional fluctuation: The 0.1 °C resolution and published fluctuation of ±0.5 °C (high temp) and ±1.0 °C (low temp) provide finer setpoint granularity and repeatable chamber conditions for routine cultivation and method development, enabling tighter experimental control across the full range.
Trade-offs
- High continuous power draw and single-phase supply dependency: The 1600 W input power and AC220V 50 Hz power supply requirement demand dedicated electrical infrastructure; facilities without compatible 220 V circuits at 50 Hz may need additional line conditioning or transformer installations, increasing deployment complexity.
- Time-limited operation and ambient temperature sensitivity: The built-in timer operates only to 5999 min, restricting unattended long-duration incubations without manual reinitiation; the specified +5 to 35°C ambient temperature range limits placement in unconditioned or hot laboratory environments, potentially requiring climate-controlled room space.
