金屬電極的差分應用
在此配置中，金屬電極搭配差分放大器使用，下圖使用DAM80，但是您也可以簡單換成DAM50(搭配#5489)、ISO-DAM8A(搭配#74040)或ISO-80。
Mutliple applications are available with a variety of options. Here you can see two setups.
Differential Applications for Metal Electrodes
In this setup, metal electrodes are used with a differential amplifier. In this setup, a DAM80 is shown, but you could easily substitute a DAM50 (with 5489), ISO-DAM8A (with 74040) or ISO-80.
利用玻璃為電極的細胞外應用
在罕見情 形下當使用細胞外放大器搭配玻璃，你可以採用下圖所示配置。在此設置中採用DAM80，但您也可以簡單的替換成ISO-DAM8A(搭配#74040)或 ISO-80。同樣的，此設置採用#2505握柄 (1/4″-6.3mm)，但是若您的顯微操縱器較小，可能需要使用#5444握柄(3/16″-4.8mm)。圖中配置採用MEH7W-10，但是任何玻璃尺寸的MEH7W均可使用。(MEH7W-10是1.0mm玻璃、MEH7W-12為1.2mm玻璃、MEH7W-15為1.5mm玻璃、MEH7W-20為2.0mm玻璃) 圖中的EP2用於接地。
單端型應用時，在黑色連接器插座上的#2033線纜適配器可連接至#3294電纜。尖端依您的需求而定。圖中建議使用#TIP1TW1。注意，下圖未顯示出玻璃。
Extracellular Applications Utilizing Glass Microelectrodes
For rare instances when using extracellular amplifiers with glass, you could use the setup shown below. In this setup, a DAM80 is shown, but you could easily substitute an ISO-DAM8A (with 74040) or ISO-80. Likewise, this setup shows the 2505 handle (1/4″ – 6.3mm), but if you have a smaller micromanipulator, you may need the 5444 handle (3/16″ – 4.8mm). In this illustration, MEH7W-10 is used, but any glass-size MEH7W could be used. (MEH7W-10 is 1.0mm glass, MEH7W-12 is 1.2mm glass, MEH7W-15 is 1.5mm glass and MEH7W-20 is 2.0mm glass.) EP2 is used for grounding in the illustration.
For single-ended applications, however, a 2033 wire adapter on the black connector socket can be connected to the 3294 cable. The tip used depends on your specific needs. In the illustration, TIP1TW1 was suggested. NOTE that the glass is not shown in the illustration below.
