Efficient liquid transfer and filtration are essential for maintaining precision in chemical and biological workflows. Professional laboratory funnels and specialized holders are engineered from high-grade polypropylene (PP) and stainless steel to ensure chemical compatibility and structural stability. As a core component of our vessels range within general laboratory consumables, these tools are foundational for sample preparation and organized liquid handling.
Why Choose Professional Laboratory Funnels and Holders?
Our curated collection of fluidic tools is designed for secure integration and optimized flow rates:
- Precision Funnel Holders: We stock LLG Funnel Holders in both polypropylene and stainless steel configurations, supporting diameters from 25 mm to 150 mm with or without integrated boss heads for secure mounting.
- Ribbed Laboratory Funnels: Utilize LLG Polypropylene Funnels featuring internal ribs to prevent filter paper from sticking and ensure a consistent stem length (80 mm) for rapid liquid transfer.
- Advanced Filtration Inserts: Explore VITLAB Filter Inserts specifically designed for barrel funnels (50 mm), enhancing your ability to remove particulates during bulk transfers.
- Durable Material Construction: Find holders and funnels crafted to withstand frequent chemical exposure and sterilization cycles in demanding research environments.

Frequently Asked Questions
1. Why use a ribbed funnel design?
The internal ribs in LLG polypropylene funnels prevent filter paper from sealing against the glass, allowing air to escape and ensuring a faster, more consistent filtration rate.
2. What is the advantage of a funnel holder with a boss head?
LLG funnel holders with integrated boss heads allow you to attach the holder directly to a retort stand without needing additional clamps, simplifying your filtration assembly.
3. Are these funnels suitable for corrosive chemicals?
Polypropylene funnels from LLG and VITLAB offer excellent resistance to many acids and bases; however, for highly aggressive solvents, a DWK Duran glass or Bohlender PTFE funnel may be required.
4. Can VITLAB filter inserts be reused?
VITLAB filter inserts are designed for durability and can typically be cleaned and reused, but they should be inspected for particulate buildup to maintain flow efficiency.
