Adapter Fractionation Connecting 75° with socket

Adapter Fractionation Connecting 75° with Socket

Fractionation setups demand precise angular connections between column assemblies and receiving flasks. A 75° angled adapter with socket joint solves this by directing vapor flow at the optimal trajectory for efficient condensation. Borosilicate glass construction handles thermal shock from -80°C to +500°C without cracking.

Optimizing Fractional Distillation with 75° Angled Connectors

The socket joint accepts standard ground glass connections from distillation columns, thermometer adapters, or vacuum takeoff assemblies. Vapor travels through the angled pathway with minimal turbulence, maintaining separation efficiency across multiple fractionation stages. Unlike straight connectors that force awkward apparatus positioning, the 75° bend keeps your setup compact on limited bench space.

Socket Integration for Column Systems

• Direct column mounting: Socket accepts fractionation column tops with precision ground joints from 14/20 to 29/42 sizes
• Claisen adapter compatibility: Connects below Claisen adapter outlets for dual-arm distillation configurations
• Thermometer well integration: Socket depth accommodates thermometer adapters for real-time vapor temperature monitoring
• Vacuum-tight seals: Ground glass taper maintains integrity down to 10⁻³ torr pressure

Thermal Efficiency in Angled Connections

The 75° geometry reduces condensation inside the adapter body compared to the sharper angles in an Adapter Bent 75° without socket. Smooth internal bore eliminates dead volume where fractions could mix. When running Rotary evaporators or complex distillations, pair with Circulating chillers and heaters to maintain precise temperature gradients. Pro tip: Pre-heat the adapter with a heat gun before distillation to prevent premature condensation that ruins separation.

Standard Ground Joint Specifications

Available joint sizes match common laboratory standards: 14/20, 19/22, 24/40, and 29/42 configurations. The socket depth follows ASTM E676 specifications for interchangeability across manufacturers. Works seamlessly with Glass Reactors requiring angled takeoff ports for continuous distillation. Borosilicate 3.3 glass meets ISO 3585 standards with 3.3 × 10⁻⁶ K⁻¹ thermal expansion coefficient. Clean with chromic acid or piranha solution between runs to prevent cross-contamination.
