Insulated Stainless Steel Erlenmeyer Flask Water Bottle · 500 mL
A scientific form, rebuilt for daily use.
The Flask Vessel is a science flask water bottle — the Erlenmeyer flask reborn in 304 stainless steel. Double-wall insulated, leak-resistant, and built to be kept rather than discarded: a drink vessel shaped from the 500 mL Erlenmeyer flask silhouette, finished in matte powder coat, and marked with permanent laser-engraved calibration graphics.
- Modeled on the 500 mL Erlenmeyer flask — holds about 440 mL to a comfortable fill line
- 304 stainless steel interior and exterior
- Double-wall insulated for daily beverages
- Permanent laser-engraved calibration markings
- Leak-resistant lid with carry strap

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.
Where is it personalized?
The primary position for laser engraving is on the back side of the flask with the name or logo oriented vertically (see customization guide). The volume markings always remain on the front of the Flask Vessel.
What else may be customized?
For individual customers, customization is limited to the primary engraving location. For bulk orders, we offer additional logo engraving on the top of the lid, as well as customized fabric wrist straps.
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?
In-stock, non-engraved orders ship within 1–2 business days from our Georgia facility, and you'll receive tracking when it's on the way. Personalized (engraved) orders take a little longer to allow for engraving, and 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.
