High-temperature Sterilizer with Adjustable Temperature Details

【High-temperature Sterilizer with Adjustable Temperature】FAQ

Q1: Can I use a High-temperature Sterilizer with Adjustable Temperature for silicone baby products like pacifiers and teething rings?


A: Yes, you can safely sterilize silicone baby products using a High-temperature Sterilizer with Adjustable Temperature. Set the temperature between 100°C and 120°C.


Silicone generally withstands dry heat up to 200°C, but staying below 120°C extends product life. Avoid exceeding 150°C, as higher temperatures may cause discoloration or hardening over time.


Recommended settings for baby items:

Item Type Temperature Time
Silicone pacifiers 100-110°C 15-20 min
Glass baby bottles 120°C 20 min
Plastic bottle parts (heat-resistant) 100-110°C 15 min
Teething rings (silicone) 100-110°C 15-20 min


Always check the manufacturer's heat tolerance label on each item before sterilizing.


Q2: How does a High-temperature Sterilizer with Adjustable Temperature differ from UV or steam sterilizers?


A: A High-temperature Sterilizer with Adjustable Temperature uses dry heat, not water or UV light.


Key differences:

Aspect Dry Heat (This Model) UV Sterilizer Steam Sterilizer
Sterilization method Hot air circulation Ultraviolet light Moist heat/steam
Temperature 100-180°C Room temperature ~100°C
Penetration Deep (air circulates) Surface only Deep (steam penetrates)
Rust risk None None High
Spore kill Yes (at 170°C+) No No
Cycle time 20-40 min 5-10 min 6-10 min


Choose dry heat for:

- Metal instruments (scalpels, scissors, forceps)

- Glass items

- Items that cannot get wet

- Heat-resistant plastics and silicone


Choose UV for:

- Heat-sensitive electronics

- Items that cannot tolerate any heat


Choose steam for:

- Quick cycles on baby bottles (moisture okay)


Q3: Can a High-temperature Sterilizer with Adjustable Temperature kill all bacteria, including spores?


A: Yes, a High-temperature Sterilizer with Adjustable Temperature can eliminate bacterial spores, but only when set correctly.


Most vegetative bacteria die at 70-80°C. Spores (such as Bacillus or Clostridium species) require 160°C or higher for at least 30 minutes.


Temperature-time guide for spore kill:

Target Temperature Time Result
Vegetative bacteria 100-120°C 15 min 99.9% kill
Most viruses 120°C 20 min 99.99% kill
Bacterial spores 160°C 30 min 99.99% kill
Bacterial spores (full) 170°C 45 min 99.9999% kill (6-log)
Fungal spores 140°C 30 min 99.99% kill


For routine disinfection:

- Baby bottles or utensils: 120°C for 20 minutes

- Medical/dental instruments: 170°C for 45 minutes


Always refer to the temperature-time guide provided with the device.
