Long Stem Glass Funnels. These are designed with an approximate 60° angle for efficient filtration and a significantly longer stem compared to the 1504 short-stem series.
Key Features
- Material: High-quality Borosilicate 3.3 glass, which is durable, autoclavable, and resistant to thermal shock.
- Design: Features a conical body with a 60° slope for optimal fit with filter paper.
- Stem Type: Long stem (typically 150 mm), which helps create a liquid seal during filtration and prevents gas escape in closed systems.
- Optical Quality: High transparency, free from bubbles or scratches.

Key Applications
- Filtration: Specifically designed to work with filter paper to remove sediments from liquids.
- Liquid Seal: In school experiments, the long stem is often inserted below a liquid level to prevent gas from escaping through the funnel.
- Safe Transfer: Ideal for filling narrow-neck containers like pharmaceutical vials or bottles with minimal spillage.
