Quartz Glass

Quartz glass has great electrical and mechanical properties. It offers the lowest dielectric constant, the lowest loss factor and the highest volume resistivity making it ideal for patch clamp recording.

Quartz Glass Capillaries (Heraeus HSQ300)

The finest and purest glass available is quartz. It is superior to all other glasses in its mechanical, electrical and optical qualities. It has the lowest dielectric constant, the lowest loss factor and the highest volume resistivity making it ideal for patch clamp recording. Its chemical purity virtually eliminates leakage of ions** and by using quartz in single channel patch clamp recordings the lowest background noise levels have been achieved***. Due to its high melting point, it cannot be pulled on conventional pullers. However, it can be pulled easily with the Sutter CO2 laser-based P-2000/G.
