Description
The properties of borosilicate glass make it the most popular material among researchers for the fabrication of electrodes and micro-pipettes.
- Easy to fill
- Two channels in a single diameter
- High quality borosilicate glass
- Outside diameters in 1.5 and 2.0 mm
- 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.
Theta wall Clark borosilicate capillaries are offered with septum dimensions of 0.17 mm and 0.22 mm.
Micropipettes and microelectrodes manufactured from Clark glass are used primarily in intracellular and extracellular research. The end user can manufacture their own microelectrodes and micropipettes using standard pipette pulling and microforge techniques.
