Make The Most Of Your Drinks With Vacuum Flasks

There's nothing better than a hot drink on a cold day, and an icy cold drink on a hot day. And with a thermos flask, you can have the best of both worlds. If you're shopping for vacuum flasks and mugs, eBay has plenty of variety on offer.

About the vacuum flask

The vacuum flask was designed in 1892 by Sir James Dewar, an Oxford University professor who worked in cryogenics (liquefied gases) - he needed to keep the chemicals at the lowest possible temperature. It didn't take time for households to start taking advantage of this technology, finding it not only kept liquid cold, but also hot. Today vacuum flasks are used for everything from tea and coffee to soup, milk and ice water.

A vacuum flask has an inner chamber, as well as an outside plastic or metal case - usually separated by two layers of glass that have a vacuum in between. If the flask is an unbreakable design, the glass won't be there – instead the flask will have two layers of stainless steel separated by a vacuum layer and reflective layer. The top has a tight, screw-down stopper that prevents air from getting in.

Shopping online for vacuum flasks

When you're shopping for vacuum flasks online, check to see what they are made of. Stainless steel is more traditional, and it can keep drinks chilled for up to 24 hours and warm for up to 8 hours. Modern versions are also made from plastic and polypropylene – these have an induction bottom and can be microwaved.

There are many different flask types to choose from and various sizes and capacities are available. You'll find two litre options, one litre and 500mls, while vacuum mugs are great for carrying your coffee while you're heading to work.
