Product Description
RELIGLAS three neck round bottom flasks offer maximum versatility for laboratory chemical synthesis, distillation, reflux, and multiphase or multi-inlet operations. Select between Parallel (02.355P) or Angle (02.355A) neck orientations to suit your exact lab setup and equipment needs. The center and two side necks accommodate common glass socket joint sizes (e.g., 14/23, 19/26, 24/29, 34/35, 55/44) for easy, leak-proof assembly of condensers, feed lines, gas inlets, thermometers, or other apparatus.
Available from 50 mL for analytical work up to 20000 mL for batch and pilot processes. Challenging workflows—such as those requiring simultaneous addition, distillation, temperature control, or inert gas blanketing—are simplified with these high-strength borosilicate vessels.
