Capsel

Robust temperature-stabilized
medication cases

Coming soon to Kickstarter

Medication cases for adventures and everyday

Capsel™ is a system of medication cases that protects your medications from physical and thermal shock so you can focus on life’s adventures.

Capsel™ keeps your meds cool

High temperatures can degrade critical medications, such as:

  • Epinephrine for severe anaphylactic allergic reactions

  • Insulin for diabetes

  • Injectable medications like semaglutide (Ozempic/Wegovy)

Keep your medications protected and with you so they are ready when you need them.

Built from your upcycled tumbler

Premium tumblers and bottles you know and trust provide unbeatable thermal insulation.

Capsel is a system of custom insulated caps and advanced heat-absorbing materials that transforms select Stanley and Yeti tumblers and bottles into robust cases for your medications.

Fits most pen-style medications

Tested with epinephrine autoinjectors (Viatris/Mylan, Teva, Amneal), insulin pens, Ozempic, and other injectables. Also fits vials, eyedrops and pills!

Even if your prescription changes, your case doesn’t have to.

No refrigeration, ice, or electricity needed

Capsel protects against high temperatures with precision-calibrated and custom-fit packets that soak up heat so your medications don’t. When the environment drops back to room temperature, Capsel self-recharges.

No dealing with condensation, chilling ice packs, or finding a power outlet.

Never lose your medications again

Capsel is compatible with popular location trackers such as AirTags and Tile Sticker. Keep track of your medications, whether on the neighborhood soccer field or backpacking across a continent.

Best-in-class temperature management

The first version of Capsel is designed to maintain Controlled Room Temperature (excursions <86ºF).

Data based on preliminary testing with Capsel SQ1 prototypes.

Keeps medications cool for

  • 15 hours in 102ºF heat

  • 6 hours in 127ºF heat

Customizable

Identify your medications or match your style. Capsel has interchangeable badges - make your own or support an artist via future collaborations.

Designed and manufactured in the USA

Carbon-fiber polymer resins produced in Indiana. Phase-change material from Ohio. Designed, manufactured, and shipped from Cambridge, Massachusetts. Capsel is safe, traceable, and ethically-made.

Designed for sustainability

Capsel creates an upcycling pathway for tens of millions of stainless-steel tumblers and bottles, using domestic small-batch additive manufacturing to reduce inventory and transportation waste.

Created by a physician-engineer

Capsel is the product of hundreds of hours of design work, thousands of hours of manufacturing validation, and built on years of engineering and medical training and practice.

Co-designed with patients and their families, Capsel is dedicated to creating the very best protection for your medications.

Innovations are protected by pending patent.

    Compatibility for additional containers is in development. Share your favorite container for consideration!

  • Some do. particularly epinephrine auto-injectors, insulin, and injectable oligopeptides like Ozempic and Wegovy. This first version of Capsel targets the USP Controlled Room Temperature specification of 20-25ºC with excursions permitted up to 30ºC (86ºF).

    Each manufacturer has a specific requirement, and often temperatures for long-term storage and medium-term preservation. Please refer to your medication manufacturer’s documentation.

  • Future swappable heat-absorbing/releasing packets for Capsel will allow for other temperature ranges for even more situations.
