An embudo de vidrio is a laboratory glass funnel with a long stem and wide mouth, designed for precise liquid transfers in chemical processes. Unlike kitchen funnels, these are made of borosilicate glass to withstand high temperatures and harsh chemicals.
The wide mouth catches liquid efficiently while the narrow stem directs flow precisely. Most models include a ground glass joint for attaching to other lab glassware. The design prevents spills during filtration, distillation, or decanting.
| Type | Use Case | Key Feature |
|---|---|---|
| Standard | General liquid transfer | 200ml capacity |
| Separatory | Phase separation | Stopcock valve |
| Vacuum | Filtration under vacuum | Flat base |
Embudos de vidrio appear in:
Most university chemistry labs use them daily. I remember setting up a simple distillation in organic chemistry lab - the embudo de vidrio connected to the condenser was critical for controlling vapor flow rates.
Many confuse these with kitchen funnels. The key differences:
According to Sigma-Aldrich, improper funnel selection causes 12% of lab accidents annually.
