The connection between the sprayer head and the flask is made with a special screw thread ground joint, connecting cap and loosening ring. If the joint ever "freezes" from reagent crystallization or residue formation, simply unscrew the connecting cap back onto the unique loosening ring and the joint will easily come apart. These sprayers will operate on as little as 1 psi (0.07 kg/cm?) air pressure with optimal results at 3-5 psi (0.21-0.35 kg/cm?). The connecting cap, loosening ring and o-ring should be removed before autoclaving.
