Clark Borosilicate Thin Wall with Filament

Product Summary

The properties of borosilicate glass make it the most popular material among researchers for the fabrication of electrodes and micro-pipettes.

  • High quality borosilicate glass
  • Easy filling due to filament
  • Available in outside diameters from 1.0 to 2.0mm
  • Exceptionally low tip impedance (less than 50 MΩ)
  • Excellent for patch clamp pipettes and microinjection needles
  • Ratio of outside to inside diameters preserved up to the pipette tip after pulling
  • Economical

The low softening temperature of this glass combined with its mechanical strength, chemical resistance, high electrical resistivity, and ability to withstand thermal stress make these capillaries the most widely used in the world.

Thin wall wall Clark borosilicate capillaries with filament are offered in a variety of outer and inner diameters all without an inner filament.

Micropipettes and microelectrodes manufactured from Clark glass are used primarily in intracellular and extracellular research. The end user can also manufacture their own microelectrodes and micropipettes using standard pipette pulling and microforge techniques.
