Best Thermos Flask – Buyer’s Guide
Now that you are ready to buy a thermos flask, we will ask you to stop. No, not forever, but for a few minutes and take a look at these buying tips. These guidance tips will help you out in knowing what exactly to look for.
Insulation
The major feature of any thermos is its insulation. You need to ensure that the thermos offers the right amount of insulation because the insulation is the reason why the liquid remains hot or cold.
But the insulation is also of two further types.
Foam insulation uses foam on the inner side to maintain the temperature. As the heat can’t pass through the foam, so the flask keeps the heat trapped inside. Or in the way around, no heat enters from outside.
The vacuum insulation works by creating a vacuum on the inner wall. So the heat neither enters nor leaves the flask.
Material
The thermos can be either made from plastic or steel. If you want to buy plastic, it would rather be a cheap option. But plastic is not reliable or durable. It can crack on slight mishandling.
Whereas stainless steel is a lot more reliable option. It is anti-corrosive and sturdy, so it lasts longer. Unlike plastic, it is not even toxic and is completely safe for hot food or liquids.
Capacity and Size
Now, this aspect somewhat depends on you only. The market will offer you a lot of different size ranges. The capacity decides how much will go into the bottle.
But it is your choice and final call. If you are out for a long day and need to carry a lot of coffee, go for a larger one.
