Five Neck Bottom Outlet Spherical Vessels

Five Neck Bottom Outlet Spherical Vessels

Five Neck Bottom Outlet Spherical Vessels are high-configuration borosilicate glass process vessels designed for advanced chemical operations that require multiple simultaneous connections. With five top necks and a central bottom outlet, these vessels offer maximum process flexibility, making them ideal for multi-input reactions, complex distillation setups, instrumentation-heavy processes, and pilot-scale production.

The spherical geometry ensures uniform stress distribution, excellent vacuum resistance, and enhanced thermal stability, while the bottom outlet enables complete and controlled product discharge.

Construction & Manufacturing

• Manufacturing technique: Precision manual flame-working
• Body geometry: True spherical form for mechanical balance
• Neck configuration:
• One central main neck (agitator / column / condenser)
• Four auxiliary necks for multiple process functions
• Bottom outlet: Centrally positioned for total drainage
• Annealing: Controlled annealing cycle to relieve internal stress
• Surface finish: Smooth, non-porous internal walls

Material of Construction
