Dewar containers are essentially special tanks for holding extremely cold liquids (think: liquid nitrogen) or gases (like elementary gases). These can help keep the liquids cold for a long period. Dewar containers are used by scientists in labs to store and transport materials that must be kept very cold. Let’s find out more about how Dewar containers function and why they’re used in research.
Insulated Dewar containers have an inner wall and outer wall with a space therebetween. And because the walls are a vacuum, there is no air. This vacuum discourages heat from entering, and helps to keep the inside cold longer. They are also made of things that are particularly good at keeping things cold: mostly stainless steel and glass.
A Dewar vessel includes an inner vessel and an outer vessel. The cold liquid is stored in the inner vessel, surrounded by the outer vessel. Usually the space between is a vacuum, which insulates against the heat. Certain Dewar containers are fitted with special lids to keep everything sealed. They vary in size, from small ones you can cradle in your hand to large tanks.
In laboratories, Dewar-type containers are crucial for transporting and storing samples that must be kept cold. For instance, scientists use them to store cells or tissues so that they remain viable for experiments. The cold does work to protect the samples so they don’t spoil. Dewar vessels are also used for experiments that require extremely low temperatures, colder than minus 150 degrees Celsius. It’s critical part of ensuring the samples will remain safe and that the research can proceed successfully.
Storage and transport in Dewar containers are well-established processes more than a century old. The first Dewar flask was developed by a Scottish scientist named James Dewar in the 1800s. He reached to store gases such as liquid oxygen and hydrogen. With the passage of time, dewar containers have evolved with newer materials and technology. And today, they’re better, safer and more insulated, too. Some even include digital temperature sensors or alarms to monitor the temperature.
