Retort Ring, Funnel Support Ring with Bosshead - Open Ring

Retort Ring also known as, Funnel Ring, Open-Ring, Support Extension Rings (60mm – 140mm). The professional-grade Top Wire Opening Support Rings feature a specialized open-front slot geometry designed for fast, seamless side-entry placement of glassware. Unlike traditional closed retort rings, these retort rings allow technicians and students to insert or remove filtering funnels, separatory funnels, and liquid-level columns horizontally without disrupting overhead tubing, condensers, or complex chemical distillation setups.

Specifications

• Comprehensive Multi-Size Fleet: Engineered to snugly hold a massive variety of round-bottom flasks, separation funnels, and filtering columns:
• 60mm Ring: Ideal for small funnels and micro-chemistry flasks.
• 80mm Ring: Perfectly sized for standard 125ml to 250ml separatory funnels.
• 100mm Ring: Optimized for medium 500ml vessels and filter holders.
• 120mm Ring: Built for larger 1000ml volumetric glassware profiles.
• 140mm Ring: 2000mL to 5000mL Heavy-duty capacity for high-volume lab containers.
• Premium Open-Side Layout: A rigid open ring design that removes the hassle of lifting tall or fragile glassware vertically out of closed loops, significantly reducing accidental breakage.
• High-Grade Metal Composition: Forged from thick, industrial-grade steel wire designed to resist bending, sag, and heavy mechanical weight under load.
• Corrosion and Heat Resistant Coating: Finished with a protective layer that withstands high lab temperatures, corrosive chemical splashes, acids, and alkaline vapor exposure.
• Integrated Support Stem and Bosshead: Each opening ring features a durable extension rod that easily clamps onto standard laboratory upright retort stands.
