- Double-wall insulated for daily beverages
- Permanent laser-engraved calibration markings
- Leak-resistant lid with carry strap
Available in five matte finishes: Ionic White, Carbon Black, Chlorophyll Green, Quantum Blue, and Cryo Cyan. Optional name or logo engraving available. Ordering for a team, lab, or event? See our custom science corporate gifts — with dedicated programs for biotech, pharma, healthcare, and laboratory teams — or request a bulk quote. Minimum order 25 units.
Frequently asked questions
Can I personalize it?
Yes. Name or logo engraving is available from $12 and is laser-engraved into the powder coat — permanent, not printed.
Is it insulated and leak-resistant?
Yes. It is double-wall vacuum-insulated 304 stainless steel with a leak-resistant lid and carry strap, built for daily use.
Can I order in bulk for a team or event?
Yes. Bulk orders start at a 25-unit minimum with one laser-engraved logo included. Request a quote, or order a $25 spec sample first (credited toward your order).
How long does shipping take?
Standard orders ship promptly; domestic laser-engraved bulk runs ship in about 7–10 days, with longer timelines for large custom programs.

THE OBJECT
The Erlenmeyer flask, rebuilt in stainless steel.
The Flask Vessel adapts the Erlenmeyer silhouette into a durable everyday drink vessel. The familiar laboratory profile remains, but the material system changes: stainless steel instead of glass, insulation instead of exposure, portability instead of fragility.

AGAINST DISPOSABLE SCIENCE SWAG
Not another catalog object with a science graphic printed on it.
Most science merchandise starts with a generic product and adds a periodic table, molecule, or lab joke. The result is often disposable, forgettable, and disconnected from the material culture of science.
