he Model P-30 vertical micropipette puller is designed for the fabrication of basic micropipettes and patch-type pipettes. It will pull micropipettes with tip diameters as small as 0.3um and moderate taper lengths (10 to 15mm). By using an included patching attachment, the P-30 will pull the standard double pull patch-type pipette. Used with thin wall glass capillaries, it will generate pipettes or needles suitable for microinjection studies. The P-30 is ideal for student laboratories and other situations which call for an economical, reliable pipette pulling device.
