※應用特色※
  • 消除錯誤並減少實驗處理時間
  • 自動數據記錄，無需手動記錄數據
  • 數據以USB方式保存，並且可以CSV格式導出，以便在電子表格和其他數據分析程序中輕鬆使用
  • 佔地面積小，可提供更多的工作台空間
  • 易於校準和驗證，自動20倍採樣平均值和低噪聲設計
  • 腳踏板可免用手紀錄數據-腳踏開關還可以最大程度地減少細胞培養樣品中可能引入的污染物
  • 電池電量低時通過自動保存和數據恢復來防止數據丟失
  • 通過將單位面積公式應用於電阻可以輕鬆計算TEER
  • 具空白處理(Blank Handling)功能，可以自動刪除背景電壓或電位差值
  • 若採樣電阻值低於200歐姆，則EVOM3的測量分辨率為歐姆解析度的1/10
  • 新的STX4電極更加精確。為增重自立式電極可垂直位於孔板的頂部，因此測量時無需握住電極
  • STX4電極具屏蔽電極可最大程度地減少電器干擾並更易於維護，可替換式刀片式電極。

※應用領域※
  • 測量上皮或內皮組織的融合，TEER和電位差
  • 細胞毒性
  • 滲透性，電導和藥物研究
  • 血腦屏障運輸(Blood–Brain Barrier，BBB)
  • 肺上皮組織研究、肺病毒感染
  • 腸道組織研究
