Vertical pull type with automated double mode for improved versatility.
The method used by this puller is to pull the glass capillary vertically, using the gravitational force of its own weight. For more versatility, two modes are provided: a single pull, which pulls at one stretch, and a double pull in which the setting is change in mid-process. The PC-10 can therefore produce long, thin micro needles for injection purposes, and firm microelectrodes for patch clamping. The change of setting in the double pull mode can be preset and then performed automatically, which represents a drastic saving of labour over conventional methods. Digital values, with the maximum output of the electromagnet and heater represented as 100, are shown on the display and the heater output is continually increased, making accurate mass production easier. This puller has several simple features to enhance ease of use, such as the employment of two weights (light and heavy) for tension adjustment.
