Difference of glass liner

When we bought glass liner flask, we found some inner is white, some inner is black. Do you know what's the difference? Let's see together.

White and pink linings refer to the color of the inner lining of the thermos bottle, while three-point and no-three-point refer to whether the vacuum insulation layer of the thermos bottle has three supporting points.

White and pink linings mainly refer to the color of the stainless steel bottle liner. White lining generally refers to the silver or stainless steel color of the bottle liner, while the pink lining refers to the pink or other colors of the bottle liner. These two colors of thermos bottle linings have no essential difference in function and performance, only in appearance, and can be selected according to personal preferences.

Three-point and no-three-point refer to whether the vacuum insulation layer of the thermos bottle has three supporting points inside. Three supporting points can form three small protrusions inside the thermos bottle liner, which can ensure the pressure balance inside the vacuum insulation layer and improve the insulation effect. Thermos bottles without three points refer to vacuum insulation layers without such supporting points inside, but they can also use other technologies to ensure vacuum insulation effects. Generally speaking, thermos bottles with three points have better insulation effects, but they are relatively more expensive than those without three points.

In summary, white and pink linings, as well as three-point and no-three-point, are different characteristics of the thermos bottle liner. Consumers can choose the thermos bottle that suits them according to their actual needs and preferences.
