Overview
A chemist preparing a large standard solution gets a machine-blown Pyrex flask with a long neck and a sharp, permanent graduation line. The neck is tooled for a polyethylene snap-cap, and large white block letters make the inscription easy to read.
The reason to buy is certified accuracy at a large volume, made to the ASTM standards for volumetric ware. The limitation is the cap: the flask uses a snap-cap rather than a glass stopper, and the listing shows both flat and round for bottom shape.
Who it's for
Quality control and teaching labs that make up bulk standards and reagents to a stated tolerance. Work needing a glass stopper for aggressive solvents, or just rough mixing, should use a different flask.
Pros and cons
- Class A tolerance
- Sharp permanent graduation line
- Heavy beaded neck
- Snap-cap included in the listing title
- Snap-cap instead of glass stopper
- Heavy and tall when full
- Bottom shape fields conflict
- Not for direct heating
Performance notes
Accuracy depends on the manufacturing tolerance and on filling to the sharp graduation line on the long neck. The machine-blown body and heavy-tubing neck add strength, and the polyethylene cap seals the neck during mixing.

Frequently asked questions
How does the snap-cap fit the Pyrex 5580-2L flask?
The neck is tooled for a No. 2000 polyethylene snap-cap and the description lists the stopper style as no stopper. The cap is described as blue high density polyethylene.
What standards does this flask meet?
The description names ASTM E-694 for volumetric ware, ASTM E-542 for calibration and ASTM E-288 for volumetric flasks, at Class A tolerances.
Can I heat a volumetric flask?
The listing gives no heating rating. Volumetric flasks are normally used for accurate measurement, not for heating.
