Overview

Swirling and storing small samples is the job of this Pyrex narrow mouth flask, with a conical body and a rim designed to reduce chipping. Even wall thickness balances mechanical strength with thermal shock resistance.

The reason to buy is the sturdy rim and even walls in a small, common flask size. The limitation is shipping: Texas orders need a permit that the seller verifies by email, and graduations are only approximate.

Who it's for

Teaching and small research labs that mix, heat gently or hold small samples. Texas addresses must supply a permit, and users who add solids often should choose a wide mouth flask.

Pros and cons

Pros
  • Heavy duty rim resists chipping
  • Uniform wall thickness
  • 25 ml graduation steps
Cons
  • Texas permit required

Performance notes

A uniform wall gives balanced strength against thermal shock, and the heavy rim guards the lip during handling. Graduations are for reading rough volumes, not for measurement.
