软件控制：

ez-gSEAL控制软件：NBSController控制压力应用并测量压力。 常用的压力可以预先设定，因此用户可以点击几个按钮进行密封和破膜。

新！ iPod Touch Control

ez-gSEAL压力控制器可由iPod Touch，iPhone或iPAD控制。 iPod Touch通过WiFi连接到服务器软件NBSController，因此您可以使用iPod Touch作为遥控器来控制设备的设备。

与传统的密封方法相比，使用ez-gSEAL压力控制器有许多优点：

使用ez-gSEAL压力控制器，可以在实验期间设置非常小的压力，以使封接持续很长时间。

膜片钳实验变得精确且可重复。当您使用注射器或口腔式吸入细胞时，通常很难控制压力。使用ez-gSEAL压力控制器时，您可以定义吸入压力和破膜持续时间。结果一致且可靠。在破膜后，膜很难重新封接，但如果发生这种情况，可以在不接触微操的情况下施加更多的吸力。

它简单而无压力。无需亲自控制压力，只需点击几个按钮即可制作封接和破膜,提高工作效率。使用ez-gSEAL，只要记录密封参数，就可以轻松达到正常的密封成功率。成功率高。

自动密封算法类似于PatchXpress®自动膜片钳系统中使用的算法。 PatchXpress用户可以使用它在显微镜下测试其密封参数，以便更容易地解决问题并降低成本。

Figure 1 Recording obtained at the Marine Biological Laboratory using the ez-gSEAL 100A pressure controller. LNV clock neurons in female Drosophila were used for electrophysiological recordings. A 6-7 micrometer diameter pipette filled with protease XIV was first used to digest the tissue above the clock neurons. The pressure setting for applying the protease XIV was 20 - 30 mmHg. When making the seal, 40 mmHg pressure was applied during the time the patch pipette (polished. Resistance ~ 17 MOhms) approached the neuron, and then -20 mmHg suction was applied to make the seal. The breaking-in pressure for this cell was -200 to -250 mmHg for 0.5 s. The holding pressure was _ 1 mmHg to keep the seal stable during the recording. This recording was obtained 3.5 hours after making the seal, and the cell was still healthy.

Figure 3 Sample AMPAR-and NMDAR-mediated current recorded from VTA DA neuron of p80 and older mouse. When making the seal, 50 mmHg pressure was applied during the time the patch pipette (Resistance ~ 2 MOhms) approached the neuron, and then -20 to -40 mmHg suction was applied to make the seal. The breaking-in pressure for this cell was -150 for 0.5 s.
