This bulb condenser is made from heavy-duty borosilicate 3.3 glass and features a 200mm condenser section with screw thread connections. The socket and cone sizes are both 14/23, and the total length measures 13". The bulb design increases the condensation surface area for improved vapor recovery in distillation setups. The borosilicate glass is autoclavable with heat tolerances including a Strain Point of 515°C, Annealing Point of 565°C, and Softening Point of 820°C.
