Similar to our larger units but is designed for carrying out reactions on a small scale, volumes of 5-15mL. Reactor body is fabricated of borosilicate glass with #25 Ace-Thred at top, 14/10 outer side joint externally threaded to allow an O-RING-CAP-SEAL connection with mating inner joint, and porosity E (4-8m) filter disc at bottom for use as a gas inlet to remove oxygen from the solution and/or for agitation (mixing). Bottom hose connection is size E. Immersion well is either quartz or borosilicate, 11mm I.D., with water jacket.
