Profile: Sutter Instrument offers precision electromechanical devices to form the fundamental tools necessary to perform biological research at a cellular level. Our Model P-97 micropipette puller is the latest generation of the Flaming/Brown type puller for fabrication of micropipettes, patch pipettes and microinjection needles. Our Model P-30 vertical micropipette puller is designed for the fabrication of basic micropipettes and patch-type pipettes. Our Lambda DG-4 offers speed & versatility for experiments requiring rapid light wavelength switching, and all the advantages of interference filter based systems, yet eliminates the temporal constraints imposed by filter switching devices.
