How to test insulation quality of the vacuum flask?
• Check the inside (that is, the suction mouth) is intact, if there is a break between layers is damaged inside the vacuum, lost heat preservation ability.
• Look inside presence of blowout trace.
• See if bottle is round. If you don't round bottle, bottle stopper can't seal, will reduce the heat preservation ability.
•Fill it with boiling water and cap it.
•Measure its temperature with a thermometer every hour or two and see what the temperature graph looks like

What is a vacuum flask glass refill&thermos flask
A vacuum flask (also known as a Dewar flask, Dewar bottle or Thermos) is an insulating storage vessel that greatly lengthens the time over which its contents remain hotter or cooler than the flask's surroundings. Invented by Sir James Dewar in 1892, the vacuum flask consists of two flasks, placed one within the other and joined at the neck. The gap between the two flasks is partially evacuated of air, creating a near-vacuum which prevents heat transfer by conduction or convection.
Vacuum flasks are used domestically to keep beverages hot or cold for extended periods of time and for many purposes in industry.
Vacuum flask is made up of the bladder, the shell and the additional parts.
1. Vacuum flask by both inside and outside the glass bottle.
Bottle in connection between the two as a body, two into a vacuum bottle wall clearance in order to weaken the heat convection, the glass bottle wall surface bright silver plating film reflection infrared thermal radiation. Bottle in high temperature, content of heat energy is not outward radiation; Outside the bottle when in low temperature, heat radiation from the bottle, vacuum flask and effectively control the conduction, convection and radiation heat transfer.
There is have three vacuum processes that cause heat transfer .
Conduction
Radiation -Another side effect of atomic motion is vibration, and vibration leads to the unexpected phenomenon of infrared radiation.
Convection - Convection is a property of liquids and gases. It occurs because when a liquid or gas gets hot, it tends to rise above the rest of the body of liquid or gas
2. Shell
The shell has a certain strength, in order to protect the tank and increase the decorative effect. Shell is made of tin sheet steel, brass, aluminum alloy, stainless steel and plastic, etc.
3. Additional parts
According to the water with different parts. Ordinary thermos to portable shell and handle, pour bottles of water, need to be equipped with cork, such as a cork, soft rubber expansion plug, ball cavity water control plastic plug, screw thread out of the cistern gyration plastic plug, etc.
It is made with two layers of glass bottles, while vacuum bottle, cut off from the air to heat transfer; Second, bottle wall coated with mercury, like a mirror reflects light, can put the heat radiation reflected back to the bottle; cover bottle cork, prevents the heat from the bottle slipped out, if used to hold water, also became a thermos.
The vacuum flask consists of two flasks, placed one within the other and joined at the neck. The gap between the two flasks is partially evacuated of air, creating a near-vacuum which prevents heat transfer by conduction or convection. Heat transfer by thermal radiation may be minimized by silvering flask surfaces facing the gap but can become problematic if the flask's contents or surroundings are very hot; hence vacuum flasks usually hold contents below the boiling point of water. Most heat transfer occurs through the neck and opening of the flask, where there is no vacuum. Vacuum flasks are usually made of metal, borosilicate glass, foam or plastic and have their opening stoppered with cork or polyethylene plastic. Vacuum flasks are often used as insulated shipping containers.
