The LEXO travel mug was initially released last year and became so popular that ThermAvant had trouble keeping it in stock.
This year, the company — founded by University of Missouri C.W. LaPierre Professor of Mechanical and Aerospace Engineering Bill Ma — has made the popular mug even better.
The original version of the LEXO mug used one of Ma’s four patents developed at MU to rapidly cool hot beverages such as coffee or tea to an optimal drinking temperature, then keep it warm for hours. It also keeps cold beverages nice and cool for hours on end.

The LEXO absorbs the extra heat of a beverage, cooling it to the ideal drinking temperature within minutes. It then releases that heat back into the coffee as it begins to cool, extending the optimal temperature for much longer than a standard vacuum-sealed travel mug. The LEXO is able to do all this without the need for complex electronics or batteries.
The original LEXO keeps beverages at the optimal drinking temperature for up to 8 hours. The new 16-ounce mug can keep hot beverages warm for upwards of 12 hours and absorbs the heat to bring your beverage to a drinkable temperature much quicker thanks to a few enhancements made by Ma and his team at their headquarters here in Columbia.
“Inside, we have modified some of the design from the heat-transfer point of view,” said Ma.
“We also changed the color options available for LEXO. Initially, we only had a metallic finish available,” Ma explained. “This year, we added powder coat and paint options in a variety of colors. Now, the newly designed mugs include glossy, matte, and extra durable ‘GRIT’ colors, which gives the mugs a contemporary look.”
ThermAvant also addressed early feedback about the weight of the LEXO. The new version of LEXO weighs approximately 140 grams less than its predecessor. New lid designs have also been incorporated into the latest revision —the older LEXO utilized a hinged flip-top lid that was less than optimal. The new lid revision allows users to choose between a revised flip-top lid and a luxury Slide Seal lid. The Slide Seal lid has a button that slides back and forth to open and close, creating a leak-proof seal.
“Since the price of our mug is a little bit higher (than a standard travel mug), so we wanted to play with everything to make sure the LEXO is perfect,” Ma said.
