P-2000是美国Sutter公司最新推出的高精度微电极拉制仪，主要特点是是可以拉制熔点很高的石英玻璃。由于石英玻璃有着优异的低噪声电学性能，同时电极坚硬，因此适合于脑片膜片钳记录。

While the P-2000 is suitable for working with most conventional glasses, its primary advantage is the ability to work with quartz glass (fused silica). Quartz offers superior material properties for a variety of research applications. Quartz is stronger than other glasses and can facilitate penetration through tough tissues which would normally break conventional pipettes⁽¹⁾ . For applications requiring a low noise glass, users will find that quartz is the lowest noise glass available^(2,4). Quartz contains none of the metals used in conventional glasses⁽³⁾. Optically, quartz is virtually free from fluorescence when illuminated.
