Keep your neurons alert all day long, whether you're running around the neurology department or studying for exams with this stainless steel vacuum flask.
Fill it with your favorite mulled hot cider or cold brew, and even if you don't get around to drinking it for hours, you can expect to find your beverage ready and waiting for you at the right temperature. The BPA-free flip cap seals tightly, so it won't leak all over your bag, and you don't have to take the lid off in order to enjoy your drink.
Built with superior grade stainless steel, these double-walled vacuum flasks use science to keep your drink hot - or cold - for hours!
Here's how it works: the space between the inner and outer flask wall is evacuated, creating a vacuum (well, a partial vacuum anyway...). In order for heat transfer to take place from the outside world into your cold drink, or from your hot drink to the outside world, it needs nearby molecules to excite. If there aren't many molecules nearby, as is the case in a vacuum, the heat's energy can't easily be passed along, so your drink stays close to the temperature it was when you put it into the flask for a really long time.
Simply stated, vacuums make great insulation!
The International Museum of Surgical Science, a division of the International College of Surgeons (ICS), maintains over 10,000 square feet of public galleries committed to the history of surgery, and an exquisite permanent collection of art and artifacts from the history of Medicine. The Museum supports its Mission through medically themed exhibitions and programs, in addition to a strong contemporary art exhibition program.
