Class B Volumetric Flasks with Snap Cap
Manufacturer: United Scientific
The United Scientific Class B Volumetric Flasks are the ideal choice for general laboratory procedures, educational settings, and large-scale industrial applications where the extreme precision of Class A is not required. While Class B flasks have a slightly larger tolerance than Class A, they provide an exceptionally durable and cost-effective solution for everyday reagent preparation and buffer mixing. Constructed from machine-blown borosilicate glass, these flasks feature a heavy beaded tubing neck for increased mechanical strength and a sharp, permanent white graduation line for clear volume verification. Each flask comes with a polyethylene snap cap, facilitating quick sealing and efficient mixing.

Key Functional Benefits:
- Cost-Efficient Bulk Packs: Optimized for high-traffic environments like undergraduate chemistry labs, allowing for easy inventory replacement.
- Rugged Construction: The machine-blown body ensures uniform wall thickness, while the beaded neck reduces the frequency of breakage during heavy use.
- Effortless Sealing: The snap cap design eliminates the need for expensive ground glass stoppers and prevents the hassle of stuck or "frozen" joints.
- Thermal & Chemical Resistance: High-quality borosilicate glass protects against thermal shock and resists reaction with most laboratory acids and solvents.
Laboratory Management Tips:
- Class B Application: Use Class B glassware for preparing solutions where a slightly higher tolerance (typically twice that of Class A) is acceptable, such as mobile phases for chromatography or general titration reagents.
- Storage Safety: When storing solutions long-term, ensure the snap cap is fully pressed down. If the contents are sensitive to light, consider storing the flasks in a dark cabinet or choosing amber-coated versions.
- Cleaning: These flasks are fully dishwasher safe and autoclavable (remove the plastic snap cap before autoclaving to prevent warping).
