Retort Ring, Funnel Support Ring with Bosshead - Open Ring

This retort ring with a bosshead is an open funnel support ring (also called a funnel ring, open ring or support extension ring), available from 60mm to 140mm. The open-front slot lets you slide glassware in from the side. Unlike closed retort rings, you can insert or remove filter funnels, separating funnels and columns sideways without disturbing overhead tubing, condensers or distillation setups.

Specifications

• Sizes: Made to hold a wide range of round-bottom flasks, separating funnels and filter columns:
  • 60mm ring: For small funnels and micro-chemistry flasks.
  • 80mm ring: Sized for standard 125ml to 250ml separating funnels.
  • 100mm ring: For medium 500ml vessels and filter holders.
  • 120mm ring: For larger 1000ml glassware.
  • 140mm ring: Heavy-duty, for 2000ml to 5000ml high-volume containers.
• Open-side design: A rigid open ring means you don't have to lift tall or fragile glassware up and out of a closed loop, which cuts down on breakages.
• Metal construction: Made from thick, industrial-grade steel wire that resists bending and sagging under load.
• Corrosion- and heat-resistant coating: A protective finish that stands up to high lab temperatures, corrosive chemical splashes, acids and alkaline vapours.
• Support stem and bosshead: Each ring has a durable extension rod that clamps easily onto a standard laboratory retort stand.
• Product of China

Recommended Applications

• Supporting separating funnels during liquid-liquid extractions, with easy access to the stopcock and quick side removal.
• Holding Buchner or Hirsch funnels during vacuum filtration.
• Keeping fragile volumetric glassware and vertical columns secure in more complex university or research distillation setups.
