There are many types of bottle sterilizers, but electric steam sterilizers and microwave steam sterilizers are the most common ones in specialized stores. Each can take different number of bottles and accessories like nipples or rings.
With the electric steam sterilizer the items for sterilizing are stacked inside with a specified amount of water without any chemicals and it takes a few minutes to sterilize. The bottles remain sterile for several hours as long as the lid isn't lifted.
Microwave steam sterilizers work in the same way except that it must be placed in the microwave. They are usually cheaper than the electric products, but you must check that all items you sterilize with this unit are microwave safe.
There are other types of sterilizers on the market like cold water sterilizers and disposable sterilizing bags. The cold water sterilizer is simply a container with a holding rack and a lid. They work by mixing a sterilizing solution or tablet with water and then fully immerse all the items in it. The disposable sterilizing bags are useful when you're traveling, as you can sterilize things very fast by adding a tablet and water. They are not as reliable as an electric or microwave steam sterilizer.
