UV 304 Stainless Steel Vacuum Cup

Drink at your exact preferred temperature with the UV 304 Stainless Steel Vacuum Cup. This 500 mL smart insulated tumbler combines double-wall vacuum engineering with real-time digital temperature monitoring and optional ultraviolet disinfection, eliminating guesswork while keeping beverages hot or cold for 12 to 24 hours.

The dual-layer construction uses food-contact-safe 304 stainless steel for the interior reservoir and a rugged 201 alloy exterior, delivering reliable thermal retention without transferring heat to the outer shell. An integrated LED sensor tracks liquid temperature continuously, allowing you to pour safely and adjust ice ratios without visual estimation. Selected configurations include active UV-C purification cycles that neutralize bacteria inside the chamber between refills, maintaining clean drinking water during extended travel, desk use, or athletic training.
