Buying Guide

Material and thermal resistance

Choose borosilicate glass for higher chemical resistance and better thermal shock performance compared with soda-lime glass

Capacity and classroom needs

Match flask size to the demonstration—small volumes (125 mL) for individual labs, mid sizes (250–500 mL) for bench demos, and liter-scale (5000 mL) for larger mixing or display

Pack size for group activities

Consider multi-packs when teaching groups to ensure consistent glassware and reduce per-unit cost; 8–12 packs are common for lab sets

Graduations and rim design

Look for graduated markings for rough volume estimation and heavy or rolled rims for improved durability and safer handling

Compatibility with accessories

Verify neck size and shape if you need stoppers, clamps, or heating equipment to ensure a proper fit and safe use during demonstrations
