Magnetic Glass Microelectrode Horizontal Needle Puller

PN-31:  $4,162.16 - Discontinued
Narishige's PN-31 is nearly identical to the discontinued PN-30 puller and is used for producing long, thin, sharp microneedles.

This puller uses a pulling method by which a glass capillary is fine-drawn using electromagnetic force. The long draw-out volume and employment of a strong electromagnetic solenoid enable the production of long, sharp microcapillary needles. The pulling tension can be adjusted over a wide range, from weak tension for gradual pulling of the glass capillary at the beginning to strong tension for the single-stretch draw-out required to make a long, thin microneedle. The heater uses a platinum plate which heats up quickly, so pulling can begin immediately, with minimal time-lag. Digital values, with the maximum output of the electromagnet and heater represented as 100, are shown on the display, making it easier to mass-produce large quantities of identical glass needles of uniform quality.

The PN-31 can run on any AC voltage from 100 - 240 and uses approximately 250 watts.
