Overview
Pyrex etches the capacity mark of this volumetric flask as a fine line through a narrow red band into clear glass. The heavy tubing neck is tooled for a polyethylene snap-cap, and the base is round.
The red band makes the line easy to find when bringing a solution up to volume. The data includes no tolerance, glass type or weight.
Who it's for
Teaching and analytical labs that make up liter scale standards. General mixing or heating tasks are better done in a beaker or conical flask.
Pros and cons
- Class A grade
- Etched capacity mark
- Red band for visibility
- Snap-cap fitting neck
- Round base needs support
Performance notes
The solution is brought up to the single etched line with the meniscus level at eye level. A snap-cap closes the neck for mixing by inversion.
