Q: What is this constant temperature incubator mainly used for?
A: It is designed for controlled heating, warming, incubation, and temperature conditioning of laboratory materials and samples.

Q: Can it be used in a boar semen laboratory?
A: Yes. It can be used to pre-warm compatible semen collection materials, laboratory containers, slides, counting chambers, and other accessories before semen collection or analysis.

Q: What is the temperature range?
A: The listed control range is approximately 5°C above ambient temperature up to 65°C.

Q: What is the listed temperature stability?
A: Temperature fluctuation is listed as ≤±0.5°C, with temperature uniformity of ≤±1°C under the specified operating conditions.

Q: Can this incubator store liquid boar semen at 17°C?
A: It is not recommended for this purpose because the unit is a heating incubator with a minimum operating temperature approximately 5°C above ambient temperature. A dedicated heating-and-cooling semen storage cabinet should be used for controlled 16–18°C liquid semen storage.

Q: Can it pre-warm semen collection materials to approximately 37°C?
A: Yes. A setpoint around 37°C is within the operating range and is commonly used for pre-warming compatible boar semen collection materials, subject to the laboratory procedure.

Q: What chamber sizes are available?
A: The listed models include working chambers of 250 × 250 × 250 mm, 420 × 360 × 360 mm, and 500 × 400 × 400 mm.

Q: How much weight can each shelf support?
A: The listed maximum load is approximately 15 kg per shelf.

Q: Should the temperature be independently verified?
A: Yes. For temperature-sensitive laboratory procedures, periodic verification with a calibrated thermometer is recommended.

Q: Where is this incubator typically used?
A: It is suitable for boar studs, pig AI laboratories, veterinary laboratories, animal breeding research facilities, biological laboratories, universities, and other scientific research environments.
