Microelectrode puller requested for electrophysiologists at the university of waterloo

The University of Waterloo Neuroscience Research Group including Dr. David Spafford and Dr. Matthijs van der Meer (Department of Biology) requests a Zeitz Model DMZ Universal Microelectrode Puller produced by Zeitz-Instruments Vertriebs GmbH in Germany. The Zeitz puller is available in North America through Dagan Corporation of Minneapolis, Minnesota for $21,560 CAD. The fabrication of microelectrodes for electrophysiological recording is an essential tool for neurophysiologists. A microelectrode puller is in use every day with research associates, post-doctoral fellows, graduate students and undergraduate students. There is only one micropipette puller at the University of Waterloo. It is a twelve year old, P-97 Flaming/Brown Micropipette Puller that has stopped functioning properly. It is imperative that a second puller be available because there is no other puller available for crafting microelectrodes at the University of Waterloo. We are looking to replace the old micropipette puller with a Zeitz Model DMZ Universal Microelectrode Puller. The Zeitz model is a new generation puller that will pull electrodes from glass and also automatically polish the tips for electrophyiological recording. There are vertical micropipette pullers which make less precise tips (Sutter P-30 / Kopf) and more expensive Laser-Based machines (Sutter P-2000), but neither of these suited to our needs. We include only one quote for the Zeitz Model puller because there is no other equivalent puller on the market.
