The use of an (expensive) peristaltic pump or syringe pump overcomes these problems, but can introduce other complications. We have recently had oc-...
of a pressure-equalizing addition funnel, and a syringe needle was attached. Judicious selec- tion of needle length, bore size, and reactant volume can be used ...
The elimination of atmos- pheric contamination, containment of odors and controlled slow addition have led to im- proved yields and less complaints from fellow ...
