  1. Why Buy a PUL-1000 Research Puller for Making Micropipettes?
    February 25, 2021
    PUL-1000 is a microprocessor controlled, four-stage, horizontal puller for making glass micropipettes or microelectrodes used in intracellular recording, patch clamp, microperfusion and microinjection. The PUL-1000 is capable of producing a vast array of pipette shapes, such as a long graduated taper, a short graduated taper and a short taper bee stingers. Here's a quick introduction the PUL-1000 research puller. The PUL-1000 puller was designed with tight mechanical specifications and precision electronics for complete control of the pulling process and accurate reproducibility. It offers programmable sequences of up
  2. Five Factors That Affect the Pulling of Glass Micropipettes
    February 22, 2021
    Pulling micropipettes or microelectrodes is a science and an art, requiring some finesse. Here we discuss the five major factors which can affect the shape of a pulled glass micropipette or microelectrode. The PUL-1000 is a microprocessor controlled, four-stage, horizontal puller for making glass micropipettes or microelectrodes. Here we will look at factors that affect the pulling of glass.  As the temperature of glass increases, the glass transitions gradually from a hard and relatively brittle solid state into a soft and viscous state. To form glass into certain shapes using a puller, heat is applied through a filament. Many factors affect the heat transferred from a filament to a glass capillary. The filament holders heat up when current passes through the filament, which
  3. Using WPI's PUL-1000 Micropipette Puller
    March 06, 2015
    World Precision Instruments' PUL-1000 is a microprocessor controlled, four-stage, horizontal puller for making glass micropipettes or microelectrodes used in intracellular recording, microperfusion and microinjection. It offers programmable sequences of up to four steps with complete control over the heating, force, movement and cooling time. This allows graduated cycles for a variety of applications. PUL-1000 can produce pipettes with tip diameters from less than 0.1µm to 10+ µm.
