An Ibex Sciences Adapter Recovery Bend is a specialized laboratory glassware component used in organic chemistry and distillation setups. It serves as a structural link that redirects hot vapors or condensed liquids out of a boiling flask or distillation column and channels them smoothly down into a cooling condenser. [1, 2, 3]
Key Specifications & Configurations
- Material Composition: Hand-blown from premium Borosilicate 3.3 Glass, providing high thermal shock resistance and maximum protection against corrosive chemicals. [1, 2]
- Quick-Fit Joint Profiles: Designed with standardized, frosted ground glass joints to build airtight, leak-proof connections. [1, 2]
- Sloping End Style: Features an angled bend (often at a standard 75° or 105° slope) to direct the pathway downward. [1, 2, 3, 4]
- Vertical End Style: A completely vertical drop profile that keeps the collection setup compact and saves bench space. [1, 2]
- Standard Joint Sizes: Available in interchangeable industrial/educational sizes like 14/23, 19/26, and 24/29 (where the numbers denote the joint diameter and length in millimeters). [1]
Core Laboratory Functions
- Vapor Routing: Connects the heating flask directly to the upper entry point of a Liebig or West condenser during fractional or simple distillation. [1]
- Solvent Recovery: Acts as a collection bridge during solvent evaporation, reclaiming expensive chemicals for safe reuse. [1, 2, 3]
- Drip-Tip Efficiency: Many variants feature an internal drip-tip design at the bottom cone to prevent liquid from spreading backward or splashing outside the receiving vessel. [1, 2]
Critical Safety & Cleaning Tips
- Never Apply Grease Excessively: Use only a minimal smear of joint grease (like vacuum grease). Excess grease will liquefy under high heat, run down the glass, and contaminate your pure distillate sample.
- Support the Weight: Distillation setups exert high physical stress on angled joints. Always place an adjustable lab bosshead and clamp directly beneath the recovery bend assembly to prevent the glass joints from snapping under pressure.
- Check for Hairline Cracks: Thoroughly hold the adapter up to the light before heating. High chemical vapors escaping a cracked joint present a severe fire and inhalation hazard. [1, 2]
