Digitimer supply a large range of pipette fabrication tools and accessories (such as heater elements and glass) provided by Narishige and HEKA Elektronik, two highly respected manufacturers of electrophysiological equipment. We can offer two stage micropipette pullers/needle pullers for production of patch or sharp pipettes, as well as electrode grinders and micro-forges or fire polishers for subsequent procedures.
Microforges & Grinders
Microelectrode Grinders allow glass micropipettes to be beveled in order to produce sharper tips. Such tips can facilitate cell penetration in studies which require intracellular recording or injection. Microforges use a heated element to melt the glass at the end of individual microelectrodes. This procedure can be carried out to produce specialist tools for cell handling during injection or be applied gently to tips to “fire polish” them prior to patch clamping experiments.
